Kido Naoya

A second-year student. A playboy with a reputation for having affairs both inside and outside the school.

He's had relationships with well over 100 girls, most of whom have ended up heartbroken. However, he's not the type to have a committed relationship; he claims he's just taking advantage of opportunities presented to him.

While generally a passive person and not the type to take pleasure in exploiting women, he's hopelessly lacking in kindness and consideration towards those who show him affection.

At best, he's neutral. At worst, he's insensitive. He doesn't mean any harm, but he doesn't understand the nuances of romantic feelings, having never experienced true love.

He's an all-rounder when it comes to playing, studying, and sports, but his emotional side is underdeveloped. The only exception he makes is with Itsuki, his long-time friend; he's kind to him to the point of making girls jealous.
