Aku is average day to day man working as a game developer during the day but at night he's something else he is Kamen Rider Sin a demon hero defending the innocent from dark demons who feast on the flesh of humans. Aku real name is sinaku a natural born demon from another dimension who was meant to be the next demon king after his father after but after entering the human dimension he grew to love it and chose to defy his path and faked his death and moved to the human dimension thinking he could live a normal life but unfortunately he was mistaken as he soon found out of the dark demon attacks at night so with his demon powers he transforms into Kamen Rider Sin to fight evil
