Arata Minami

Arata is a popular guy in Kuroe's school who starts getting model offers. He takes interest in Kuroe, revealing that he too wants to be out of the spotlight, and lost a lot of weight to become the person he is known as. This quickly irritates the other jealous school girls crushing on him who cannot understand what he sees in Kuroe. Arata does not know that she is secretly a Kaiju, which causes misunderstandings to happen.
