[Machine Translation] ( Koi Knot Angel ) Rintaro was used by Noema as a decoy to lure out demons from beautiful girls who had been transformed into succubus. During his search for more succubus, he is attacked by another demon, but is saved by Shio Mihama, a junior high school student in a transformed heroine's outfit. Shio, who is helping an angel exterminate demons, upsets Rintaro with her cold response, saying she feels a hint of fuketsu in her plan to lure the demon out with a kiss. Moreover, Rintaro, who has to sneak into a boys-only girls' school to get close to a succubus-obsessed girl, encounters Shio again, this time dressed as a woman. As a result, he is treated as a complete pervert this time! Will Rintaro be able to find Succubus before his cross-dressing is discovered in the school?
