Broken sig

In Diary of Broken, he is a graduating college student in Kaizen University, of BS Information Technology. He makes a dark deal with his best friend Muji "Null" Noritaka to make sure that his girlfriend, Mato "Format" Shimizu doesn't fall into the hands of the best friend who betrayed him. Broken dies horribly, with a stab on his heart, his right arm cut, his mouth peeled off, and a stab in his left eye ultimately killing him. It was all part of Null's secret plan, which is somewhat unexplained.

After his death, he avenges Format in Zeryte form, killing his other executioners, Exit and Code. Unfortunately, a twist in the story occurs, making his reality twisted.



Broken as he appears in the EP (close-up).

He is sensitive, kind, yet psychotic when it comes to some tragic things. He is also extremely emotional. Before he died, he was afraid of bloody things and sharp knives. But he had overcome that fear and became obsessed with killing and looking at his bloody face. However, from time to time, he feels guilty about what he does, as he is still a faithful Roman Catholic. He says that he just needs support from his friends.

About his Nationality

Broken and his sister Miki actually have a Polish father, who settled in Japan as an orphan and was adopted by a Japanese family. This is why both of them have blue eyes.
