文月 海

Kai is most known for his bighearted, lively brotherliness, making him popular among and respected by other males. Being the eldest son among six siblings, Kai has developed a natural 'big-brother'-like personality, and has a habit of patting everyone on the head. He is naturally welcoming and accepting, although according to Haduki You, he can end up pampering others too much, especially Procellarum's leader Shimotsuki Shun.
