Kazuichi Soda (左右田 和一 Sōda Kazuichi) is one of the characters featured in Danganronpa 2: Goodbye Despair.
He has the title Ultimate Mechanic (超高校級の「メカニック」chō kōkō kyū no mekanikku”).
Kazuichi returns in Danganronpa 3: The End of Hope's Peak Academy as one of the students from Class 77-B in Hope's Peak Academy with the other Remnants of Despair. Kazuichi succumbed to despair along with his classmates after being brainwashed by Junko Enoshima and became a part of Ultimate Despair.
Kazuichi managed to survive the final trial and escape back to the real world with the other survivors at the end of Danganronpa 2 and remained on Jabberwock Island. He and his classmates who awakened from their comas decide to atone their sins as the former members of Ultimate Despair.
In Danganronpa V3: Killing Harmony, it is revealed that he, the rest of the students of Hope's Peak, and Hope's Peak itself were actually fictional and were only part of the in-verse Danganronpa game and anime series.
He is voiced by Kyle Hebert, who also voiced Dorulumon, Ballistamon, Greymon from Digimon Fusion, Greymon from Digimon Adventure tri., Ryuji Suguro from Blue Exorcist and Kiba Inuzuka from the Naruto anime.
Kazuichi tries to put up a front of being a cool tough guy, but it's just a facade, and a very thin one at that. In actuality, Kazuichi is an easily-rattled coward who spends most of the Despair Game being completely terrified of everything he comes across, causing him to seem fickle and unreliable as a result.
Kazuichi also has a serious crush on his classmate Sonia Nevermind, but unfortunately, he has no idea how to express it. As a result, every time he attempts to flirt or get close to Sonia, he just winds up creeping her out, as well as everyone around him. When Sonia takes interest in Gundham Tanaka, Kazuichi is extremely jealous and has a very hard time accepting it.
However, despite all of his faults, Kazuichi still has a good side. When Akane is heartbroken over her friend Nekomaru's death, Kazuichi stays up all night and builds a mechanical Nekomaru doll for her. Also, after Gundham's death, he gives Sonia time to grieve, since despite his jealousy, he knew that she cared for him.
