Daisuke

Daisuke is Mitsuo's best friend since childhood and classmate. He was a rather decent guy when the series started but when the journey started and he didn't take his medication he became a annoying idiot who became obsessed with food and acted like a baby and dog. He was useful at some parts like giving Zowie the fake sword even though he found out it was fake and he actually handed him the REAL sword! Also he did Zowie's impression to trick Ren into forfeiting the tough battle. And lastly he acted like a dog and bit Zowie's arm weakening him. Daisuke has a mother, father and a younger sister named Izumi. He's also been banned from several restaurants.
