Why watch after Overflow: Choose this if the 'borderline' nature of the relationships in Overflow was what kept you watching.

Is Overflow a Hentai or an Ecchi anime?
Overflow is technically part of the 'ComicFesta' (AnimeFesta) line, which produces short-form series that often have two versions: a censored 'On-Air' ecchi version and an uncensored 'Premium' version that contains explicit adult content.
How many episodes are in the Overflow anime?
The anime consists of 8 episodes, each roughly 6 to 7 minutes long. It follows a chronological watch order, starting from the sisters' unexpected visit to Kazushi’s apartment and escalating through their shared living situation.
Does Overflow have a manga I can read?
Yes, the anime is based on the manga by Kaiduka. The manga provides much more context regarding Kazushi's relationship with Ayane and Kotone and continues the story well beyond the events shown in the 8-episode anime adaptation.
Natsuo ends up in a complicated love triangle when his father remarries, making his crush and his first sexual partner his new stepsisters. It is a messy, high-stakes romantic drama.
