Ryo is a charming and outgoing young man and he has a natural charisma that attracts others to him, making him popular with women. However, under the surface, he's manipulative and callous, using many of the women who fall in love with him for his own financial gain in one way or another with complete disregard for their well-being.
Kairi is Ryo's younger brother. The two don't particularly get along and Ryo has a track record of stealing Kairi's girlfriends, but whenever Kairi's in a pinch, Ryo usually lends a hand.

Sae is Ryo's ex-girlfriend. He never really has feelings for her and he abuses her naivete by coercing her into his pyramid scheme by threatening to cut off contact with her, along with convincing her that more distasteful things he gets her into are for her own good. Although for a moment he believes that he might be able to have a family with her, the moment he realizes that Sae's pregnancy wasn't real, he leaves without another word.
Ryo's ex-girlfriend. He initially steals her from Kairi and ropes her into his pyramid scheme, but later cuts off contact with her when she's in debt, eventually taking her car as payment. Although Ryo doesn't think of Morika at all, Morika is dead-set on bringing him physical pain.
