Eri Morita is the central female character in the adult OVA and CG collection Succubus Yondara Gibo ga Kita!? (also known as I Summoned a Succubus and My Stepmom Appeared!?).

• Double Life: By day, Eri lives a quiet, respectable life as a seemingly ordinary human housewife. In reality, she is a succubus who slipped into the human world years ago and has largely suppressed her demonic instincts to integrate into society.

• The Summoning: The core premise kicks off when her teenage stepson, Takashi, successfully completes a grueling 72-day abstinence challenge to perform a succubus summoning ritual he found online. To her utter shock, the ritual's magic binds Eri and pulls her straight into his bedroom.
