In the 1960s manga and anime series "Vampire" (also known as "Banpaiya" or "The Vampires") by Osamu Tezuka, Chippei is a supporting character and the younger brother of the protagonist, Toppei Tachibana. He resides within a community of vampires, a species defined not by traditional traits like blood-drinking or immortality, but by their ability to transform into animals. Each member of this community has a unique and often peculiar trigger that causes their transformation. For Chippei, this trigger is the sight of anything round in shape. This specific condition leads to his involuntary transformation into a werewolf, an animal form he shares with his older brother, Toppei.

Chippei's personality is largely defined by his role as a loyal and helpful younger sibling. His primary motivation within the story is to support his brother Toppei. As a major conflict emerges from the vampire community's plans to incite a revolution against humanity, Chippei becomes an integral part of the effort to stop this threat. He works alongside both his brother and the manga artist Osamu Tezuka, who appears as a character within the narrative, to prevent the chaos that the vampire uprising would bring. He does not act as a lone hero but as a key member of a small group dedicated to preserving the peace between species.

Chippei possesses a notable ability beyond his lycanthropic transformation. He has a very keen sense of smell, a trait that proves to be of great practical use to his allies. This heightened olfaction allows him to track individuals or detect things that others cannot, making him an invaluable asset during their mission to stop the vampire revolution. While Chippei does not undergo a significant personal transformation arc in the available information, his character is consistently portrayed as a brave and capable figure who contributes his unique skills to the group effort. His loyalty to his brother and his courage in the face of a world-threatening conspiracy are the defining features of his role in the story.
