Kumiko Aso

Shy outcast Kokoro has been avoiding school for weeks when she discovers a portal in her bedroom mirror. She reaches through and finds herself transported to an enchanting castle where she is joined by six other students. When a girl in a wolf mask explains that they have been invited to play a game, the teens must work together to uncover the mysterious connection that unites them. However, anyone who breaks the rules will be eaten by a wolf.

Yasuo (Hiroshi Abe) grew up as an orphan. He married a woman he loved and they had a son Akira (later played by Takumi Kitamura). Yasuo's life seemed great at the time, but his life totally changed after his wife died in accident. Since that time, Yasuo, who never experienced parents' love himself, has to raise his son Akira alone.
