Seiyuu

Ishiya’s path toward becoming a voice actor started with a setback in his life.

During middle school, he assisted backstage for a children’s theater troupe at a friend’s invitation and developed an interest in acting.

But at that time he was more invested in track and field, being active as an athlete. However, he ended up suffering an injury during a competition in his second year of high school.

According to Ishiya in an interview for ddnavi, the next day, the doctor told him, “You can’t do track and field anymore as a high school student“, so he had to give up.

While hospitalized, he was deeply moved by a line spoken by Hiroshi Nohara from “Crayon Shin-chan” and decided to pursue voice acting seriously.

He attended a university in Gunma Prefecture. During that time, he was working part-time to save money for the enrollment fee for a training school plus the expenses of traveling to Tokyo, starting from zero acting experience.

He graduated from the Pro-Fit Voice Actor Training School.

And in 2013 he was ready to debut.

2013 – 2016

Making a name for himself

He debuted as a voice actor in 2013, kicking off the year with several minor roles in tow. Some of his minor roles were in anime series such as Golden Time and Strike the Blood.

In 2014, he got minor roles in No Game No Life, Majimoji Rurumo, Gekkan Shoujo Nozaki-kun, Nobunaga the Fool and Ookami Shoujo to Kuro Ouji.

2015 would open the doors for the first-ever supporting role with a considerable amount of time on screen for Haruki Ishiya.

He was cast as Shuuichi Tsukamoto, calm and easy-going trombone player, in the music/drama anime series, Hibike! Euphonium.

In 2016, Ishiya continued to get minor and supporting roles with very few lines in anime series such as Saiki Kusuo no Ψ-nan and Mobile Suit Gundam: Iron-Blooded Orphans 2nd Season.

Still in the same year, he voiced Pyuma, one of the leading characters in the sci-fi animated movies, Cyborg 009: Call of Justice.

Other anime series in which he voiced characters include:

• Sekai de Ichiban Tsuyoku Naritai! (2013)

2017 – 2019

First leading role and new opportunities

In 2017, Haruki Ishiya finally got a chance to voice a main character in an anime series. He was cast as Tamotsu Denkigai in the action/ecchi anime series, Akiba’s Trip -The Animation-.

This was the very first time that people would get to listen to Ishiya’s acting for more than just a couple of seconds – like in many of the minor and supporting roles he’d gotten in the past.

And he did a solid job in this anime – despite it not having been quite the hit that some expected it’d be, seeing as it was based in a game.

In 2018, Ishiya was cast as Alex, a loyal member of Ash Lynx’s gang in the popular crime/action anime series, BANANA FISH.

A year later, he joined the main cast in the drama anime series, Kono Oto Tomare!.

He voiced Saneyasu Adachi, a second-year student at Tokise High School and a member of the Koto Club.

Still in the same year, he was cast as Masato Oosuki, one of the main characters in the comedy/fantasy anime series, Do You Love Your Mom and Her Two-Hit Multi-Target Attacks?.

Wrapping up the year, Ishiya was cast as Keisuke Sudou, the male main character in the romance/hentai anime series, XL Joushi.

This character has a double cast, with Ishiya voicing Keisuke only in the televised version.

Masahiro Yamanaka voiced the character in its hentai version.

2020 kicked off with a main role as the initially insensitive yet with a heart of gold Jin Mazama, in the anime series, Seton Academy: Join the Pack!.

The time arrived for Ishiya to reprise his role as Buster Bros!!!’s Jiro Yamada in the first anime season of Hypnosis Mic: Division Rap Battle – Rhyme Anima.

He ended up reprising his role in its 2nd season in 2023. For those that were not still familiar with his voice acting – and rapping – his performance in this series ended up putting a different spotlight on him.

From this point on, and seeing how popular the Hypnosis Mic franchise turned out to be, Ishiya started to have more eyes on him, opening the doors to new projects.

Other anime series in which he voiced characters include:

• Katsugeki/Touken Ranbu (2017)
• Youkai Apartment no Yuuga na Nichijou (2017)

In 2021, he joined the main cast as Tsurayuki Rokuonji in the romance anime series Bokutachi no Remake.

A year later, things quieted down a bit to the point that Ishiya was active voicing characters in anime series such as Youkoso Jitsuryoku Shijou Shugi no Kyoushitsu e 2nd Season, Eternal Boys and Kami Kuzu☆Idol.

In 2022, upon Pro-fit closing doors, Haruki Ishiya left the company and joined Office Osawa. Since then and at the time of first writing this Seiyuu Digest, Ishiya is represented by Office Osawa.

This change provided a breath of fresh air in his career.

2023 would bring back a couple of roles Ishiya had voiced in the past.

He reprised his roles as Shuuichi Tsukamoto in the movie Hibike! Euphonium: Ensemble Contest-hen and Jiro Yamada in Hypnosis Mic: Division Rap Battle – Rhyme Anima +.

In 2024, he was cast as Akiteru Ooboshi, the male protagonist in the My Friend’s Little Sister Has It In for Me!.

After that, he hosted his own radio shows and co-hosted shows tied to anime or 2D music projects.

Some of those shows include:

For this show, Ishiya talked a bit about his life and family as well as answered questions from his listeners.

As a bonus, he had a “Haruki Clinic” corner in which he listened to listeners’ recent episodes of anger and offered advice to calm their anger.

Haruki Ishiya Radio de Migaku (2020 – 2023)

From 2020 to 2023, Haruki Ishiya hosted the radio show “Radio de Migaku“. This was his first ever solo radio show – not part of the MONTH TWO MONTH special radio.

Games

His first steps in voicing characters in games were in 2014. He started off voicing minor characters in Sword Art Online’s tie-up game and from that point on, he started to branch out.

Fans can find him voicing characters in anime tie-up games, rhythm games, RPGs, action, fighting, otome (adventure and romance), and mecha games.

His first leading role as the protagonist (name is chosen by the player) in Pilgrim Saga (2015).

Some of the characters he’s best known for include (this list is not extensive):

Teppei Shirayuki in Band Yarouze! (2015 – 2019)

Band Yarouze! started to be distributed on October 12, 2016, after some hiccups that delayed its release, and easily turned into one of the most exciting rhythm games in the industry.

The game counted with an attention-grabbing story that followed the dealings of 4 different rock bands.

The game’s band lineup counted not only the main 4 bands – OSIRIS, BLAST, Fairy April, Cure2tron – but also the legends DesTIRARE and the rival bands CrystalCross and Freezing.

Ishiya voiced the passionate and caring Teppei Shirayuki, BLAST‘s drummer.

Although he is tough-looking, something that usually scares children and makes most people think he’s older than he is, Teppei is a 16-year-old with a heart of gold.

Despite the announcements of new bands joining the lineup and a new storyline kicking off in 2018, the reality was that Sony and Aniplex ended up putting Band Yarouze! in a weird “alive-but-not-really” situation.

Updates ceased to be delivered to the game, however, the game is still playable.

Jiro Yamada in Hypnosis Mic – Alternative Rap Battle – (2020 -)

Ishiya reprised his role as Buster Bros!!!‘s Jiro Yamada in the smartphone game, Hypnosis Mic – Alternative Rap Battle –.

Jiro is an easy-going and confident individual who’s not afraid of being rowdy with others to defend his brothers. Although he’s lived in the shadow of his older brother, Jiro slowly learns that he needs to treat him as an equal and carve his path.

The game features a short introductory story for each crew, with Ichiro’s love for his brothers and passion for hip-hop being highlighted in all story parts.

Sebek Zigvolt in Disney Twisted-Wonderland (2020 – )

In 2020, he joined the cast of Disney Twisted-Wonderland.

He voices Sebek Zigvolt, a first-year student at the Diasomnia dormitory. He is extremely pleased to have been admitted to the Night Raven College, the same school as his respected Malerus. He tends to argue with Silver due to differences in opinions.

Louis in Fire Emblem Engage (2023)

In 2023, Ishiya joined the star-studded cast of the popular RPG, Fire Emblem Engage.

Music

Haruki Ishiya started to be active in the 2D music industry back in 2016 as he joined the powerpop band BLAST however he’s best known for being a member of the groovy rap trio, Buster Bros!!!.

He’s best known for being part of the following 2D music groups:

BLAST (2016 – 2019)

2016 welcomed an ambitious rock rhythm game, Band Yarouze!. The franchise introduced 4 main bands: OSIRIS, BLAST, Fairy April and Cure2tron.

BLAST‘s lineup counts with Youji Ikuta (vocals), Daiki Yamashita, Haruki Ishiya, and Toshiki Masuda.

The band has a youthful yet aggressive punk-rock/punk-pop sound that easily sets it apart from all other music within the franchise.

Since their debut, BLAST released a couple of insert songs for the game – that were later released in Duel Gig albums – and performed live twice.

Since for the Duel Gig live shows only the vocalists for OSIRIS and BLAST attended, Masuda never took part in any of the franchise’s live shows.

Aside from the group songs, Ishiya performed solo (as Sosuke Maki) on “heartbeat“, song later released on DUEL GIG EXTRA, Best Of album released in November 2018.

BUSTER BROS!!! (2017 -)

Known for their free and groovy rap style, Buster Bros!!! are a beloved crew within the Hypnosis Mic franchise.

With the cast including Subaru Kimura (as Ichiro), Haruki Ishiya (as Jiro) and Kouhei Amasaki (as Saburo), Buster Bros!!! have a fun take on rap, with 3 completely different vibes converging to creating their unique, bouncy hip-hop.

The voice actors have grown to be like a family, with Ishiya and Amasaki learning rapping skills from Kimura, which has vastly helped the crew improve their delivery for each new song they present to their fans.

The crew debuted in 2017 with the release of the imposing single, Buster Bros!!! Generation.

Buster Bros!!! were overflowing with energy for their debut release.

After the release of the introductory singles for each crew, Hypnosis Mic kicked off their 1st Battle Season series.

Buster Bros!!! faced MAD TRIGGER CREW in the first round in Buster Bros!!! VS MAD TRIGGER CREW.

The mini-album was a huge success much thanks to the voting system for the whole Battle Season that only made it possible to vote if you purchased the CD in physical or digital format.

Buster Bros!!! VS MAD TRIGGER CREW was certified Gold by RIAJ in 2018.

Buster Bros!!! ended up losing their battle against MAD TRIGGER CREW but it was still a tight one, only decided in the last days of voting.

In 2019, the crew released the playful おはようイケブクロ (Ohayou Ikebukuro), featured in the compilation album, Enter the Hypnosis Microphone.

The crew returned in 2020 with the release of Buster Bros!!! Before The 2nd D.R.B, a critically acclaimed album that brought plenty of cool, groovy songs exuding freedom and fun that is unique to this crew.

Ishiya performed the slow-paced, introspective, and unique School of IKB.

In 2021, the group participated in the 2nd Division Rap Battle series, first going head-to-head with Doutsuitare Hompo in “Dotsuitare Hompo vs Buster Bros!!!“.

Buster Bros!!! went on to beat Dotsuitare Hompo, advancing for the very first time to a final in the Division Rap Battle series.

On a live setting, Buster Bros!!! showcase impressive chemistry and coordination, with no one being left behind or outshining others. In that sense, Buster Bros!!! are as good live as Fling Posse are.

With Subaru Kimura leading the way, the live Buster Bros!!!, are a force to be reckoned with.

Their chemistry stands out, with members covering for each other in a pretty seamless way and rhymes flowing like it is second nature to all members.

Due to Subaru Kimura’s charismatic self overflowing with energy and never missing a beat, Haruki Ishiya and Kouhei Amasaki shine.

As a result, the crew is lively and intense on stage. So far the crew has performed live 7 times, although in different contexts.

The first franchise release on Blu-ray and DVD is Hypnosis mic- Division Rap Battle – 4th LIVE @ Osaka, massive live held in 2019 that counted with Buster Bros!!!, MAD TRIGGER CREW, Fling Posse, Matenro, and the, then recently announced, Dotsuitare Honpo and Bad Ass Temple.

In 2020, and due to issues with Coronavirus (COVID-19), Hypnosis Mic’s ambitious MetLife Dome live, SIX SHOTS TO THE DOME was cancelled.

Instead, all crews performed on 29/03/2020 on a special broadcast by AbemaTV, Hypnosis mic- Division Rap Battle – 5th LIVE @ AbemaTV – SIX SHOTS UNTIL THE DOME that counted with millions of live views.

In January 2021, the Hypnosis Mic held its 6th live “2nd D.R.B”, with the 3rd battle counting with Dotsuitare Hompo vs Buster Bros!!!.

Arriving like a wrecking ball of emotions, Buster Bros!!! battled Dotsuitare Hompo in “Dotsuitare Hompo vs Buster Bros!!!“.

The trio won the battle with the massive “Re:start!!!“.

During this live show, Buster Bros!!!, Matenro and Fling Posse premiered the final battle song “SHOWDOWN”.

Buster Bros!!! went against Matenro and Fling Posse in “Buster Bros!!! VS Matenro VS Fling Posse”.

The battle was fierce for the title of “Champion” but ultimately, it was Fling Posse that took the title with them, with Buster Bros!!! grabbing 2nd place and Matenro in 3rd.

Later in August 2021, the crew performed live at Hypnosis Mic 7th live “SUMMIT OF DIVISIONS”.

Kicking off the year, Buster Bros!!! participated in Hypnosis Mic’s 2nd full-length album “CROSS A LINE“.

The crew performed “IKEBUKURO WEST BLOCK PARTY”, song that channels good vibes right from the start.

At the time I reviewed this song I wrote “Fighting spirit and pride take over and lead the way for Buster Bros!!!’s “IKEBUKURO WEST BLOCK PARTY”, song that is, easily, the best the crew has released so far.“

Still in the same year, the crew was back on stage for Hypnosis Mic -Division Rap Battle- 8th LIVE《CONNECT THE LINE》.

In April 2023, the Hypnosis Mic franchise held a large-scale live show featuring all crews titled Hypnosis Mic -Division Rap Battle- 9th LIVE ≪ZERO OUT≫.

In August 2023, the group participated in the franchise’s 1st ever EPs.

This was the first time that members of all rap crews participated in shuffle groups, brought bands to the spotlight

As Jiro, Ishiya participated in “The Block Party – HOMIEs –”, performing “Get busy” alongside Kuko Harai (CV: Shota Hayama).

In January 2024, the Hypnosis Mic franchise released “Welcome 2 Rhyme Anima+”, album including all the songs featured in Hypnosis Mic -Division Rap Battle- Rhyme Anima +, the 2nd season of the franchise’s anime series.

The CD includes Buster Bros!!!’s new song “Bring it on“.

In April 2024, the franchise got together yet again for its 10th live show, Hypnosis Mic 10th LIVE “LIVE ANIMA”.

Division All Stars (2017 – )

Division All Stars‘ original lineup consisted of Buster Bros!!!, MAD TRIGGER CREW, Fling Posse and Matenro. In 2019, with the addition of Dotsuitare Honpo and Bad Ass Temple to the franchise, the group now houses all groups.

Their first release was Hypnosis Mic -Division Rap Battle- in 2017. This was the explosive start even before anyone knew how each crew would end up sounding.

The song was an instant hit and brought a massive following from overseas to the project.

In 2018, Division All Stars returned with the electrifying Hypnosis Mic Division Battle Anthem. The success it met was even more than on their debut song.

Now that the project was popular, it was a matter of a couple of days until it hit 1 million views.

In 2019, Hypnosis Mic released its first compilation album. Enter the Hypnosis Microphone featured all of Division All Stars‘ songs plus a new ensemble track, Hoodstar.

The release also included new songs for each group including the legendary The Dirty Dawg – from which Kimura’s character, Ichiro, was a part.

The song was quickly followed by Hypnosis Mic – Alternative Rap Battle-, song featured as the theme song for the smartphone game, Hypnosis Mic -Alternative Rap Battle-.

Still in the same year, Division All Stars returned with a new take on their debut song, Hypnosis Mic Division Battle Anthem.

After the franchise introduced 2 new units to the franchise, Dotsuitare Honpo and Bad Ass Temple, the classic track got a revamp, thus Hypnosis Mic -Division Rap Battle-+ was released.

In 2020, Division All Stars made their comeback and once again revamped one of their hit songs. Hypnosis Mic -Division Battle Anthem- was revamped, adding Dotsuitare Honpo and Bad Ass Temple into the mix, creating Hypnosis Mic -Division Battle Anthem-＋.

And in 2020, Division All Stars released the fan favorite, and up until July of the same year, ingame exclusive, Survival of the Illest.

Still in the same year, Division All Stars released the funky tune “SUMMIT OF DIVISIONS“. The song was included with the franchise’s Hypnosis Mic – Division Rap Battle – Official Guide Book.

A year later “Hypnosis Mic-Glory or Dust-“ was released.

The song featured a 3D CGI animated music video – the first one in the Hypnosis Mic -, going in line with the franchise’s recent bet in VR and CGI technology to improve the visibility of its contents.

A couple of months later and still in 2021, Division All Stars released an extended version of the groovy hit tune “Survival of the Illest“.

The reworked song was titled “Survival of the Illest+” and included Dotsuitare Hompo and Bad Ass Temple in the recording.

In the summer of 2021, Division All Stars released “Hang out!“, one of the funkiest songs so far released by the group.

Still in the same year, the group released a new – extended – version of “Hoodstar”. Now including the rapping by Bad Ass Temple and Dotsuitare Hompo, “Hoodstar+” was released.

In 2022, the Hypnosis Mic franchise released its 2nd full-length album “CROSS A LINE“.

In this album, which included new songs by all crews, there is the groovy self-titled all-star song.

With the premiere of the 2nd season of the anime series in 2023, Division All Stars released the digital single “RISE FROM DEAD”.

Alongside Makoto Furukawa, Yoshiki Nakajima, Kento Ito, Yoshiki Murakami, Kengo Kawanishi, Shun Horie, and Takeaki Masuyama, Haruki Ishiya is part of Hoshikuzu Ryodan, group that has a hybrid approach to jazz music.

The group released its first CD JAZZ-ON! Sessions 「Ryodan nakama wa shinjite mo, rakuda no himo wa shibatte oke」 in 2019.

Due to the franchise’s unusual organization of pair and group songs, in this CD, Kawanishi didn’t perform any song.

In 2020, the group released JAZZ-ON! Sessions 「星屑寄れば文殊の知恵」(Hoshikuzu Yoreba Monju no Chie).

In this CD, Ishiya showed his vocal chops by performing alongside Takeaaki Masuyama in “Tomorokoshi hata no numuhogu“.

At the time I reviewed the CD, I wrote “Out of both, I was only unaware of how Haruki Ishiya would sound like as a singer, but I must say that I am pleasantly surprised. Sweet mid-tones, good control over his vibrato, and knows how to harmonize.“

In 2021, the JAZZ-ON! franchise kicked off its very 1st shuffle CD series. The series would end up having a total of 4 CDs.

Haruki Ishiya participated in “Tone of Stars Beta”. He performed the self-titled song “Tone of Stars Beta” alongside Kent Ito, Yoshiki Nakajima and Kengo Kawanishi.
