Ui's husband. He's high-spec, handsome, and brilliant. On the surface, he's polite and kind to everyone. However, his true motto is that only money and specs never betray you, and he calls himself trash. Despite that, he loves Ui more than anyone else and snaps if she's ever in danger. He understands Ui better than anyone.

A boy with heavy, devoted love. He originally came to Nanami Academy to become Ui's partner, but failed. He's willing to commit crimes for Ui's sake. (In the manga, he often says things like 'Let's kill that guy!' which is part of his charm!)

A small, cute girl. Her nicknames are Mei-chan or Mei-san. She loves Ui and is almost always with her. She speaks with a somewhat boyish/blunt tone. She often tells Shintaro he's annoying by saying things like 'Shut it!'

Mei's partner who absolutely adores her. He views Ui as a good ally. He calls Kon 'Smiley' and is quite harsh toward him.
