Bonsai and androids have something in common. That means living for a much longer time than a person's lifetime. Kanna, an android, is being taught bonsai by a ``teacher'' at the bonsai shop Kifuen. Kanna looked at her teacher in wonder as she talked about the wonders of bonsai. Many years have passed, and at Kifuen, where Kanna is now the only one left, a new person comes to visit. This is a completely new human drama interwoven with androids living in eternity and bonsai.
