Itadaki Kazuya

Itadaki Kazuya is a large Deadman in Deadman Wonderland. He is known for eating a lot. His nickname, "Masu", is a pun when combined with his given name; the word itadakimasu is the traditional Japanese expression used when beginning a meal. He has been shown to have a very large appetite, consuming masses of food over a short time.

Appearance
Masu is a very larger man, but not very long (about Ganta's height). He has black hear that he wears in a topknot. He has a round head and his mouth is ripped open through the sides, but it is stiched. He wears a dark blue overall over the standard prison uniform. The bottom part of the overall ends at his knees. At the height of his stomache, there is a zipper on his overall.

Personality
Masu is most known for his large appetite. He will eat anything that can fill up his stomach. It also seems that he is never satisfied and always wants more. If someone refuses that he can eat something, Masu will try everything to eat that thing in the end. He also says that he will go on a diet, but postpones it every time. This shows that he is aware of his abnormally appetite but doesn't have a strong resolve to do anything about it. He also does not seem concerned with the nature of the food he is eating as he has been shown eating plates, metal bars and other items most people would find impossible to consume.

He is also used to DW's insanity, as he was unmoved by Senji's penalty game.

Deadman arc
Masu first appears accompanying Chaplin, Minatsuki and Idaki Hitara to welcome Ganta into G Ward. Chaplin introduces him as an "ugly fatso". At the welcome party, Masu continues his eating habit and bites a large piece of a robot who came to deliver food. Then Chaplin turns on the tv and Senji's penalty game comes up. Just like the others (excluding Ganta of course), Masu doesn't seem phased at all by the horror of the operation and continues eating.

The day after the party, Masu was roaming the corridors of G Ward and encountered Minatsuki. He approached her and tried to eat her flowers. But then Ganta intervenes and offers him his breakfast Masu gladly accepts and Minatsuki and Ganta run away. After Masu ate Ganta's breakfast (including plate and cutlery), he still complains about being hungry.

Return to DW arc
After DW was closed, Masu had a retrial. He was sent to a normal prison together with Chaplin. He is seen there eating his cell walls and his urinal.
