Yami wakes up to Luna the AI who asks about her change of heart. Yami replies that it's due to life at Sainan. Rito also wakes up to Momo. Momo is curious to see Rito's development towards her harem plan. She confirms that Rito is the perfect centerpiece because many girls have fallen for him. She also notes that Yami has gotten softer towards him. Rito questions Momo's theory as he sees Yami uneasy with Tearju. Momo and Rito then ask Ryouko about Yami. Ryouko notes that Yami cannot recall memories of her first visit to her office. Momo remembers Nemesis talking about Yami being unaware of her Darkness ability. Later, while Momo thinks about her harem plan, Rito speaks to Yami about problems with Tearju and hiding her past. Yami questions Rito's interest and tells him to back off. The meeting ends when he accidentally falls onto Yami and gets unwanted attention. Later at the pool, while students examine Tearju's revealing swimsuit, Mea talks to Yami as sisters. Yami thanks Mea for inspiring her to start a new peaceful life on Earth. As Mea and Tearju agree, Yami feels a jolt as her body glows. Suddenly, Yami's transformation goes berserk. Mea is confused until Nemesis tells her that Yami is transforming into her true form: Darkness. Nemesis also possesses Mea and locks her away ensuring the inevitable rampage and their future as assassins. Tearju, shocked, confronts Nemesis regarding Yami. Nemesis answers that Yami was created to fight and cause destruction. Admitting peace triggers this backup mode to protect Yami's identity as a weapon. Nana also demands Nemesis to return Mea's body but Nemesis lies that Mea has always been a false personality of her. Once the transformation is complete, Nemesis greets Darkness.
