Kip. 7: After School at 14
Rika reaches her 15th birthday, and she asks her inattentive mother to reveal the identity of her missing father as she had promised. However, as her mother had engaged with numerous men at the time, even she is unsure who her real father is. When Rika enters the Egg World, she is tasked to protect Shino, a girl who had participated in a cult suicide. Shino defends the Wonder Killer form of her cult's leader, and, defeated, Rika questions her existence, allowing the Wonder Killer to attack her. However, she is protected by her Pomander, Mannen, and becomes motivated from its support as well as her friends. Rika defeats the Wonder Killer and comes to terms about her birth, admitting to her mother that she will leave her when the time is right. (Source: Wikipedia)
