Osamu Koekawa

Osamu Koekawa (越川理, Koekawa Osamu) is a student at Binan High School who admires the Student Council from afar. His outward appearance can be likened to that of an angel, but his voice is changing in accordance with the growth of his body. Therefore, his real voice is deep, making him sound like an old man. Because he feared his voice becoming "dirty and ugly" as he gets older, there was a gap in his heart which Furanui's Magic Knights, Edelstein, took advantage of, transforming him into the Voice Change Monster. Those that touched the beam he fired out of his mouth had their voices deepen considerably and all they could say was "Boeeeh".

Appearance
Osamu is a small boy with messy and short light brown hair and brown eyes. He wears an over-sized pink cardigan with a large red, school uniform tie over it. Along with the pink cardigan, he wears the standard black uniform pants and brown shoes.

Personality
A small and skittish boy, Osamu deeply admires that Student Council. He wants to stay young and angelic forever, but the deepness of his voice distorts his view of himself and allows Edelstein to turn him into a monster. Once he reverts back to his former self, he is still terrified of the idea of becoming an old man.
