Deep Feelings ~ Im Innersten.Yuka, who has been in love with Kohta since childhood, caught him in several awkward situations with Nyu (such as changing her clothes for her after the last episode because her other clothes are wet), causing her to become increasingly jealous of Kohta's concern for Nyu. Mayu, a 13-year-old girl and her dog Wanta, who witnessed the incidents in episode 2, return an umbrella left by Kohta on the beach to him, where she is interrogated about the events. Meanwhile, Nana, codenamed "No. 7", another diclonius who calls Kurama "papa," is released from her confinement to track down Lucy and bring her back to the facility.
