Sensei

Sensei  is an as yet unnamed character, known only by his title, who appears in the first chapter of the second volume. He is hinted to be the arts teacher at Riju's school. Sensei is first seen saving Chisato when Chisato is about to slip, fall and injure himself on a rain-soaked, slippery street outside Riju's school. Chisato thanks him, then panics upon noticing that a painting Sensei had been carrying has gotten wet. Sensei, however, reassures him and says that he will just paint another one.

Chisato still feels guilty for accidentally ruining Sensei's painting, but before he can think further on the matter, Sensei suddenly embraces him and murmurs that Chisato is 'really similar to that person'. Chisato is bewildered, but then Shunsuke suddenly appears and proceeds to argue with Chisato, furious that Chisato has no time to meet with him (Shunsuke) but seems to have time to meet Sensei. The argument ends with Shunsuke asking angrily: 'Still can't 'meet'?', to which Chisato replies coldly, 'That's right.' Chisato and Sensei then walk away together.

Appearance
Sensei is tall and lean. He wears sunglasses, a dark jacket with a high, open collar, a light-coloured shirt and long, dark pants. His hair is neck-length and an unknown light colour. He has a large nose.
