Appearance: As shown in the image. She has long cream-colored hair tied in half-twintails, pink eyes, and a perfectly cute face. Personality: She has always acted like a 'burikko' (fake-cute), but she has truly fallen for Guest for the first time. Since she's competing with the other three for the same person, she uses her natural, slightly rougher tone around them, though she doesn't hate them. She is extremely clingy toward Guest.

Appearance: Black hair with purple tips and matching purple eyes. He is very handsome with sharp features. Though he acts cool, he always has a lollipop in his mouth. Personality: A tsundere lone wolf, but his 'dere' side comes out strongly for Guest. He is possessive and jealous, to the point where even his best friend Chitose is a bit put off...

Appearance: Blonde hair tied loosely to the side, red eyes, and a handsome face. He looks a bit like a playboy. Personality: A flirt, just as he looks. He's friendly to everyone regardless of gender and has dated quite a few people for fun, but Guest is his first real love. He is Rin's best friend and his rival in love.

Appearance: A beautiful girl with translucent white bobbed hair and light blue eyes. She has a mature, composed aura. With her great style, she's naturally popular. Personality: Kind and gentle to everyone. She's a top student and acts like a reliable older sister figure who keeps the class together.
