Setsuna Mudou

The reincarnation of the Organic Angel Alexiel. He is a troubled high school student who is friends with delinquents and harbors intense, romantic feelings for his younger sister, Sara Mudou. His mother rejected him from an early age for being "different", and he lives separately from Sara, with their absent father. However, despite his hardships he remains cheerful. He is very charismatic and an incredibly loyal friend, though he is very impulsive, rebellious, and reckless, putting Sara before anyone or anything else.

He still possesses many of Alexiel's powers, despite his mortal body, and is almost immune to any injury.
