Gundam Tanaka
Gundam has a eccentric and rather dark personality. He claims that he has been blessed with the evil powers of the underworld, and he refers to everyone else as “pathetic human beings.” Gundam is often lost in his own little world; he is often paying more attention to himself and his hamsters than the things that are going on around him. Gundam seriously cares about his animals, and he understands them better than he understands people. He has an informational website about breedings which he maintains carefully.
Gundam kills Nekomaru Nidai in Chapter 4, trying to save his friends from starvation. He is executed by Monokuma when he is found guilty by Hajime Hinata.
