Atsuhiko Tachibana

is a main character in the PS2 version of Piyotan, and the Kazama family doctor.

Background
An elite doctor in the United States, Atsuhiko is also the family home doctor for the Kazama family. Although being raised far from them, he seems to have a decent relationship with the Kazama's, Satsuki calling him by the nickname 'Acchan'.

Appearance
Atsuhiko has neat, nape-length dark blue hair with a slight left parting and light blue eyes, and is of a fair height. He usually wears his doctors coat over a striped blue shirt with a pocket on the left breast, a black tie, a brown leather belt and beige/cream trousers. As they aren't seen in-game, it's impossible to discern what types of shoes he wears.
