Ґеро Акоя

Akoya Gero is a 2nd year at Binan High. He looks like an angel, and is as noble as an angel, but once he is made fun of, he turns into a snappy individual. It also appears that he doesn't seem to like Zaou too much.

He transforms into "The Pearl Chevalier, Perlite" (Hanasakikeru Shinju no Shuvarie, Peruraito).
