Danganronpa: Trigger Happy Havoc

Daiya Owada (大和田 大亜) is a minor character featured only in flashbacks during the end of the second chapter of Danganronpa: Trigger Happy Havoc. He was the founder and former leader of the Crazy Diamonds, Japan's largest motorcycle gang and the older brother of Mondo Owada.

Daiya has black hair and appears wearing a white coat, white pants, and white shoes. The back of the white coat has the symbol of the Crazy Diamonds, which is a diamond with the name of the gang, “Crazy Diamonds”, around it.

Daiya died on the night of his retirement party to save Mondo, who had been driving too recklessly in an attempt to win the race that Mondo himself challenged to, and he could have been ran over by a truck if not for the intervention of his big brother. Daiya's dying wish was for his little brother to lead the gang in his stead, and to not let it fall apart.


Mondo Owada:

Daiya was Mondo's older brother, who founded and led the Crazy Diamonds biker gang up until the day of his death. Mondo states that when he was younger, Daiya would always explain about a promise between two men. He and his little brother were participating in a motorcycle race, and Mondo became reckless while he was attempting to prove himself to the gang and Daiya. He sped into the wrong side of the road, and was about to crash into an oncoming car.

Just before he was struck, however, Daiya pushed him out of the way, knocking him to the side and taking the blow from the car himself. He died in Mondo's arms, telling him to not let the gang be broken up. It was a “promise between two men”, which Mondo did his best to keep.

When this secret is finally revealed, Mondo explains how guilty he feels for not only killing his brother, but for not being able to uphold the last promise he made to Daiya.


Danganronpa: Trigger Happy Havoc:

  • Daiya and Mondo's names, when put together in order of older brother, and then younger brother (in the gang, first leader, and then second leader), mean “diamond” (ダイヤモンド). This is connected to the name of their motorcycle gang, which is the "Crazy Diamonds".
  • The name of the gang ("Crazy Diamonds") is actually a reference to the character Josuke Higashikata from JoJo's Bizarre Adventure, whose stand name is "Crazy Diamond."
  • He is indirectly referenced in Mondo's Ultimate Talent Development Plan school festival seasonal event with Angie Yonaga. Mondo mentions that his brother taught him that people who snap at girls are trash, and Angie replies that no matter what, Atua will be watching over him like a "macho, reliable older brother".
  • Daiya along with Mondo both make an appearance in another Spike Chunsoft game, Kenka Banchou Bros: Tokyo Battle Royale. In this game, he is given the non-canon title of Super High School Level Souchou. The name 'Souchou' can be translated into 'President' or 'Secretary-General' in English.

Kyoko Kirigiri's Mother

Gender: Female.png Female / Status: Deceased / Voiced by: None
Kyoko Kirigiri's mother is a minor character mentioned in Danganronpa: Trigger Happy Havoc and Danganronpa Kirigiri. She was Jin Kirigiri's wife, whose death had a major impact in the lives of her daughter and husband.

Her full name is unknown, but in Danganronpa Kirigiri her maiden name is revealed to be Uzuchi, which means a "rabbit hammer". In the Japanese culture, there is a well-known story about a rabbit hammering mochi in the moon, and thus her maiden name could be a reference to her husband's space-related execution. Her father's name was Tōhachirō Uzuchi and he was a master of seven Japanese martial arts, who taught his granddaughter self-defense.

After Jin was kicked out of the Kirigiri family due to not wanting to become a detective, he and his wife had Kyoko. Jin's father Fuhito Kirigiri then wanted him back after finding out about his granddaughter, wanting to make Kyoko his heir. He started to train Kyoko, but her mother suddenly turned ill and had to be hospitalized. When Kyoko was only seven years old, her mother was close to dying while Fuhito and Kyoko were doing detective work abroad, but to Fuhito, being a detective was more important than a dying family member and he refused to let Kyoko see her dying mother. As a result, Kyoko's last memories of her mother were "a white face floating above a hospital bed".

According to Jin, his wife was the only thing holding his relationship with his father together and it all imploded after she died, with him leaving the family in anger after his father showed no care for his dying wife.

His shoulders are broad and in the English versions has the initials for "Robo Justice" and in the Japanese version it has kanji.

Robo Justice's Appearance in Japanese Versions

Robo Justice's Appearance in English Versions

It's possible the "Justice Hammers" used in Danganronpa: Trigger Happy Havoc 's Case 3 are what Robo Justice might use in his anime series. As such it can be speculated he delivers "justice" with them.



It is unknown where Robo Justice actually comes from in the Danganronpa universe, but similar to Hifumi Yamada's passion for an anime character named Princess Piggles, he has the same feelings towards Robo Justice. So it's very likely he is an anime character as well. This is further backed up by the fact Hifumi has merchandise modeled after Robo Justice, specifically a pair of underwear, and mentions him when bemoaning the lack of 2D at the beginning of Chapter 3.

Chapter 3 - A Next Generation Legend! Stand tall, Galactic Hero!:

Robo Justice is a cardboard suit created by Hifumi in order to frame Yasuhiro Hagakure for Kiyotaka Ishimaru's eventual murder. Celestia Ludenberg enlists Hifumi as her accomplice, by lying to him that Kiyotaka forced her to steal Alter Ego, and that he was planning to kill Hifumi. Later the two frame Hiro by putting him in the Robo Justice suit, and make it look like the robot was responsible for Hifumi's "kidnapping, both Hifumi's and Kiyotaka's "murders" and the "attack" on Celestia with the Justice Hammers.

Sayaka Maizono's Idol Group

Danganronpa 1 CG - Sayaka Maizono singing with her idol group.png Sayaka Maizono's Idol Group is a unnamed idol group in Japan that existed prior to The Tragedy. Consisting of five girls led by Sayaka Maizono, the group gained popularity and fame after having done exceptional performances across the country.

Although how exactly the idol group was formed is unknown, Sayaka stated that she had done many bad things in order to become an idol, so it is implied that this goes for the whole group. The girls became extremely popular, not only in Japan, but worldwide. They had so many fans and admirers that their own lead singer, Sayaka, was invited to Hope's Peak Academy and granted the title of Ultimate Pop Sensation.

Despite their success, the girls ended up disbanding the idol group when Sayaka was trapped in Hope's Peak Academy. The remaining four members later appeared in a video, in which they appeared to be dead. It is unknown whether the group was brought together and was either knocked unconscious or forced to cooperate in recording, as the video was meant to push Sayaka to commit murder as part of Monokuma's motive. The desperation that Sayaka held after watching the motive video drove her so far to carry out her plan to murder Leon Kuwata, which ended up backfiring herself as she was the one who was killed instead by Leon during the Killing School Life. Currently, it is unknown if the other idol members are aware of Sayaka's demise.

Following these events, it is revealed that Ayaka Haneyama, one of the member of Sayaka's idol group, was forced to participate in the Demon Hunting as a target of the Warriors of Hope. However she was revealed to have survived The Tragedy. The statuses of Satomi Aoba and the remaining two members are currently unknown.

Toranosuke Ishimaru

Gender: Male.png Male / Status: Deceased
Ishimaru's Grandfather in the manga.png Toranosuke Ishimaru is a minor character mentioned in Danganronpa: Trigger Happy Havoc.

He was the grandfather of Kiyotaka Ishimaru and the father of Takaaki Ishimaru. He was a genius and the former Prime Minister of Japan.

Toranosuke was very smart and he he climbed the ranks to be the Prime Minister of Japan due to being a genius.

Everything he did, he did without any actual effort, and he never knew failure. Because of this, he became more self-centered and arrogant over his talent, which lead to a corruption scandal. After only a few months in office, the public opinion of Toranosuke changed from high praise to widespread criticism and he was forced to step down. After that, Toranosuke's business collapsed and the Ishimaru family was left mistrusted and in huge debts. His family name shamed, Toranosuke allegedly spent the last years of his life in shamed silence.

Toranosuke died a few years before his grandson enrolled in Hope's Peak Academy and only his family members came to his funeral. Apparently, he had enrolled as the Ultimate Manager[4] as well during his school years.


Kiyotaka Ishimaru:

Toranosuke's grandson, Kiyotaka, considers his grandfather someone he both hates and respects. He is bitter at his grandfather, but also seems to feel sorry for him and feels that his grandfather's tragedy taught him an important lesson. One of Kiyotaka's main goals in life is to surpass his grandfather and reach greater accomplishments than anything he ever did, with pure effort.

Because of Toranosuke, Kiyotaka considers genius' fate a tragedy and he believes that effort is most important. He also hates the word "genius" and dislikes geniuses, considering them his enemies.

Toranosuke and his grandson both have the same favorite underwear brand. Considering that the underwear often symbolize close relationships in Danganronpa, this may imply that they were very close despite their conflicted relationship.
