Mondo Owada (大和田 紋土 Ōwada Mondo) is one of the characters featured in Danganronpa:Trigger Happy Havoc. He holds the title of Ultimate Biker Gang Leader (超高校級の「暴走族」chō kōkō kyū no “bōsōzoku). He was the second leader of The Crazy Diamonds, Japan’s fiercest and largest Biker gang.

He killed Chihiro Fujisaki in Chapter 2 in the boy's changing room in a fit of rage and jealousy. He was later executed after being voted guilty in the subsequent class trial.


Mondo Owada is a fairly tall and muscular young man with slightly tanned skin, defined facial features and purple irises. The eyelashes on the outer halves of his lower eyelids are distinctively long and he usually keeps a fierce expression. His natural hair color is dark brown. Mondo's overall appearance is very typical of a Japanese biker gang (a.k.a. 暴走族 bōsōzoku) member, starting with his very unusual hairstyle. The top of Mondo's hair is styled in a trademark bōsōzoku kind of perm that is a crossover between a pompadour and the late 20th century Japanese hairstyle known as the "punch perm" and is dyed a light reddish-brown. Other than that the rest of his hair is kept it's natural color and straight texture at medium length.

Mondo's attire consists of a black overcoat known in Japan as "tokkō-fuku" (特攻服), adorned with the symbol of "The Crazy Diamonds" along with Japanese text and dragon motifs in orange, worn open over a white A-shirt, baggy black pants held up by a belt and white loafers - all very distinct biker gang articles of clothing. The buckle of Mondo's belt is shaped like the face of a lion-dog.


Behaving like a stereotypical delinquent, Mondo is foul-mouthed and can come off as a rude individual. He is very easy to provoke, and will not hesitate to resort to violence if he starts to lose his patience. Just like Chihiro, he has a severe complex about being seen as weak, which he represses by constantly repeating in his mind that he is strong. This complex stems from the fact that his gang members tended to look down on him due to his status as the little brother of Daiya Owada, the first leader of The Crazy Diamonds.

Mondo states that he tends to be very nervous around girls that he likes, causing him to raise his voice and ultimately scare them away, something that has happened at least 10 times already. He also has a soft spot for dogs and had one named Chuck in the past. His final free-time event reveals his insecurity about his future. He believes that the only choice for him after high school is over is to get a job and decides that he would choose to become a carpenter, since he wants to start making things instead of breaking them.


[Warning: Several spoilers follow this section!]

Prior to the TragedyEdit

Before Mondo was the leader of the Crazy Diamonds, he was second in command to his brother, Daiya whom he revered and respected greatly. He called him the “best gang leader in Japan” and it was because of him that Mondo initially joined the gang. Intimidated by his brother's great charisma and success, and wanting to prove he was not inferior to him, Mondo challenged his brother to a street race the night of Daiya's retirement as leader.

During the race, Mondo's desperation caused him to be too reckless and he found himself in the way of a truck. Just as the truck came racing forward, his brother swerved in to push him out of the way, and consequently, Daiya was hit in lieu of Mondo. His dying request was a promise to keep the gang together.

High School Life of Mutual KillingEdit

Along with the other students, Mondo was trapped along with the other students by Monokuma in the academic coliseum. When Monokuma reveals the rules of the academic coliseum, Mondo becomes enraged. Makoto Naegi tries to calm him down, but Mondo ends up punching him. Later, Mondo apologizes for the way he behaved in the gym. 

After the murder of Sayaka Maizono in Chapter 1, Mondo is nominated (along with Sakura Ogami) to stand watch over the crime scene. When it is time for the Class Trial, Mondo begins to suspect Makoto, but is later persuaded to find another culprit. When the trial is over, Mondo is shocked and angered as he comes to terms with his new life.

In the start of Chapter 2, more details of Mondo's personal life surface. Later, Monokuma reveals his second incentive. After the breakdown of Chihiro, Mondo tries to help Chihiro calm down. Chihiro wishes to become strong, and thinks Mondo could help. Later, Chihiro reveals his secret to Mondo. Surprise, which later turns to extreme jealousy and rage, overcomes Mondo.

The strength that Chihiro possessed reminded Mondo of the strength he lost. In a fit of rage, he hits Chihiro with a dumbbell. He then disposed of Chihiro's bag and "switched" the crime scene by bringing Chihiro's body to the girls changing room and swapping the carpets and the posters of both changing rooms. Mondo also broke Chihiro's e-Handbook by throwing it into the sauna (as he learned firsthand after his sauna competition with Kiyotaka Ishimaru that extreme heat is one of the few things that can break the e-Handbook), in order to keep Chihiro's secret.

Surprisingly, Byakuya Togami witnessed his entire ordeal and, wanting to "make the case more interesting", proceeded to further tamper with the crime scene by hanging Chihiro in a crucifix position with the extension cord from the library's desk lamp, and writing "Bloodbath Fever" on the wall using Chihiro's blood. Aside from providing himself with amusement for the upcoming class trial, Byakuya had another motive in tampering with Chihiro's murder scene in that particular way: to uncover Genocide Jill, a serial killer hiding amongst his classmates, by pinning the murder onto him.

After the events of the second class trial, Mondo is found guilty. Mondo truly feels bad for what he did, and much to the dismay of Taka, his dear best friend. Monokuma sends Mondo off to be executed.


Main Article: The Cage of Death


Daiya OwadaEdit

Daiya was Mondo's older brother, who founded and led the Crazy Diamonds biker gang up until the day of his death. He and his 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.

Kiyotaka IshimaruEdit

Mondo and Taka did not get along at first, which was not surprising, as Taka was the “Ultimate Moral Compass”, while Mondo was the “Ultimate Biker Gang Leader”. They formed a sort of rivalry, which quickly escalated to the two spending a prolonged period of time in a high-temperature sauna. This was to show a test of manliness, and whoever were to give up would be the lesser man. However, as soon as this event was over, the two acted as if they had been seemily inseperable. They would laugh together and have their arms around each other's shoulders in a “friendly” matter.

When Mondo was found guilty in the second trial, the only person who did not vote him as the culprit was Taka, who voted for himself instead. With this, it seemed like Taka was willing to have himself and everyone else die before he would let Mondo himself. He broke down, bawling and screaming, yelling and asking why he did it, clearly devastated that he was losing such a close friend.

During the third Chapter, when Taka was speaking with Alter Ego, the program changed its appearance and attitude to match that of Mondo's. Through Mondo's inspiring words, Taka then went through a self-proclaimed “transformation”, in which his and Mondo's “spirits” became one. He started addressing himself as Kiyondo, which is a culmination of both his and Mondo's names.

Chihiro FujisakiEdit

The first time they interacted, Mondo lunged at Byakuya for making Chihiro cry. Mondo seems to hold a protective side, especially when it comes to (since he thought Chihiro was a girl) girls, and stood up for him. The next day, he accidently shouted and caused Chihiro to cry. Mondo immediately apologizes and promises not to shout again. In hopes of gaining strength, Chihiro would later ask Mondo to train with him, revealing that he was male and wanting to change from being weak to strong.

Mondo, feeling jealousy of Chihiro's inner strength, kills him in blind rage, with the use of a dumbbell. Mondo soon regrets his actions and attempts to make it up to Chihiro by keeping his secret for as long as possible by switching the crime scene and broke his e-Handbook. Mondo later is executed willingly by Monokuma after being discovered as the culprit.

  • The kanji for "Mondo" (紋土) means “family crest” and “earth/soil”
  • "Owada" (大和田) is a combination of the kanji 大 - “big”, 和 - “peace”, and 田 - “rice field”, meaning it could be translated as “big rice field of peace”.
  • In the shack in the Greenhouse located on the 5th floor, there is a pickaxe with the name of Owada's biker gang on it, the "Crazy Diamonds". The origin of the pickaxe is yet to be revealed.
  • The name of Mondo's gang is most likely a reference to Josuke Higashikata's Stand 'Crazy Diamond' (written and pronounced in Japanese as 「クレイジー・ダイヤモンド」Kureijī Daiyamondo) from Jojo's Bizarre Adventure: Diamond is Unbreakable, which is in turn a reference to Pink Floyd's nine-part composition "Shine on You Crazy Diamond".
    • Mondo's hairstyle and clothing are likely to be references to Josuke Higashikata as well.
    • Incidentally, there is also a Daiya Higashikata. This character, however, is female and a distant relative of the aforementioned Josuke Higashikata.
  • The names of the Owada brothers, when put together (as DaiyaMondo), can be interpreted in Japanese as “diamond” as mentioned above. This is stated by Mondo to be where his bike gang's name, The Crazy Diamonds, comes from.
