Pagachu

Pagachu is a Japanese Original Video Animation (OVA) series that was released from June 19, 2023 to the present.

Characters
Pagachu is a naughty but cute mouse alien who is the former spy of The Grand Yaka who came from planet Yaka to find the weaknesses of planet Earth so The Grand Yaka could use them to invade Earth. Whenever Pagachu reveals a weakness of Earth to The Grand Yaka, her enemy-turned-owner Chaniwa Rumina would always stop their invasion. She eventually became Chaniwa Rumina's pet in the 7th OVA after she found out that the leader of The Grand Yaka lied to her about the mission and that he sent her to Earth just to get rid of her. She is the older sister of Yumi and Hiroku (all three who are related to Chimpui).

Chaniwa Rumina is a 10 year old girl living with her mother and sister. She is the only one who knows that Pagachu is an alien but never really tells anyone about it since she knows that no one would believe her. She is in love with a boy named Kenichi and is constantly bullied by Einosuke and Arata. Chaniwa at first didn't got along with Pagachu but became nice to her after finding out that she was actually sent to Earth because The Grand Yaka wanted to get rid of her.

Junko Rumina is a 59 year old woman who is the single mother of Chaniwa and Machiko.

Machiko Rumina is a 2 year old baby who is the younger sister of Chaniwa.

Yumi and Hiroku are both alien Mice who are the younger sisters of Pagachu.

Eionsuke Toriyama is a 12 year old fat boy who attends the same School as Chaniwa. His way of bullying Chaniwa mostly involves sexual harrasment (ex. pulling up her skirt or slapping her butt). It is mostly implied that he bullies Chaniwa because he is secretly jealous of her being in love with Kenichi and that he secretly likes her.

Trivia

 * Pagachu stating that she and her sisters are related to Chimpui implies that Pagachu was originally meant to be from Planet Mahl but there were legal issues that prevented Waku OVAs from revealing that Pagachu is from Planet Mahl.
