Sister Bomber!

Aoi (Eiko Koike), Yuuka (Mika Katsumura), and Misa (Eri Kitagawa), childhood friends from Kiraboshi Garden who were separated in their childhood, reunite after a long time. The reason for their reunion is to help save the church that has fallen into debt. Just then, it is revealed that the ex-boyfriend of a woman who came to confess is the same person as Yuuka's ex-boyfriend. It seems that he is a terrible man who has been deceiving many women using the same method and getting them to give him money. Yuuka decides to infiltrate her ex-boyfriend's place alone...

One day, a boy named Tokio, who seems to have a troubled past, wanders into Kiraboshi Kindergarten. Tokio is a mischievous boy who causes trouble repeatedly around the kindergarten. He claims that he has been kidnapped and is on the run. Suspicious, Aoi (Eiko Koike) and the others decide that it would be best to send Tokio home for the time being.

Toru then invites Aoi on a date, telling her that she needs a break once in a while. Aoi, who has never been on a date before, finds herself increasingly drawn to Toru. However, one day, men arrive with a promissory note stating that they will hand over the church as collateral for a debt, and the church is trashed...
