Momo also blames herself for not intervening given that she was already suspicious of Mea. Rito assures Momo by talking to Nana himself. He finds Nana inside a virtual space filled with her animal friends. Nana tells Rito how she wanted to help Mea as Mea was always alone. Despite her efforts, Nana feels that Mea never saw her as a friend and was only playing with her. Rito hugs Nana and assures that she can still make up.

She reminds herself that she is a weapon and only befriended Nana to bring Yami out. Nana finds Mea and confronts her. Mea, fixated on her identity, keeps Nana away by attacking her. Momo tries to intervene but Rito stops her. Nana dodges Mea's attacks until Mea activates her Psycho Dive. With the ability, Mea finds out that Nana consulted with Rito.

Mea is unsure about Nana's words but accepts her request to be friends again. Yami, who happened to be dealing with the alien assassins targeting Mea, arrives. Mea thanks Yami and admits she partially understands Yami's words on emotions and feelings. At night, Nana can't sleep and she remembers how warm Rito's hug was and decides to sneak into bed with him, but as usual, Momo was already there and Rito gets beat up by Nana.
