Senri Shioya

A Category D, like Mana, except his power is that he has the ability to shape-shift.
He refers to himself as "the pursuer of true love".

Finally understanding the truth of love he transforms into his true form, Nine Tails, and launches himself at the incoming alien bombardment. Sacrificing himself he takes out 90% of the incoming threat, saving the Earth.

Senri was able to survive his sacrificial act when his soul miraculously inhabited the doll Kuumi gave to him prior to his heroic deed.
