Chizuru Tachibana

Some years ago he visited Japan. He happened to meet Yuuki and Yuuta in the process. Initially when he met Masaki Sato, he claimed that she was not cute because she was violent and always reject other people's kindness. However as the story developed, he began to fall in love with Masaki and even get jealous when Masaki only talks to Shun.

Chizuru is half-Japanese and used to live in Germany. When he was a child he came to Japan for a short time and became friends with Yuuki. Although at that time he didn't know any Japanese when he later moved to Japan during the second year of high school he was already fluent in Japanese. Chizuru has a very cheerful personality and is a bit of an idiot. He has a huge complex about his height and does not like his shortness to be pointed out. Chizuru has a crush on Masaki though he is well aware she likes Shun.
