Souta Suzuze is the leading role in this play. He is a middle school student, age 14. He is the key to the world of Adai and Van Dowley. His father was Adele Kaze Jun Tyrone, and his mother was originally from Van Dowley. Snow White often calls him "Mr. Caotai".

Mrs. Cao heard some voices, and he was lured into the alley of Akihabara by these voices. This is how Mrs. Cao met a man who called him "the key of Eldai". The man suddenly turned into a nightmare demon and attacked Cao Tai. At this time, a talking wolf saved him, and together with Little Red Riding Hood, he repelled the nightmare demon.

Souta Suzuze is not very old, but he is easy-going, kind and good-tempered, and he is really like a grass. She is gentle, slim and kind and takes good care of Little Red Riding Hood. In addition, Little Red Riding Hood is naive and free-spirited, and girls like considerate boys, so Little Red Riding Hood likes bluebells.
