Miharu Ayase

Miharu Ayase is Haruto's (Rio's previous incarnation) 1st love and childhood friend. In volume 4, the reincarnated Haruto, Rio, found Miharu and company in the forest. Rio was confused on how to interact with her again as his moral values were different from those when he was Amakawa Haruto. He also detested the idea of involving Miharu and those he holds dear into his revenge towards Lucius. This stemmed from the fact that he felt guilty of killing people despite being necessary. Hence, he felt that he is not qualified to be close to her nor is he qualified to attain happiness. Later, Aisia bestowed a dream upon Miharu, a dream about Haruto after they separated and Rio before they reunited again. This spurred Mahiru to approach Rio more aggressively compared to her usual shy/timid personality. Aisia also warned Miharu that Rio is a kind yet cowardly person as he does not want the people he loves to enter his life because he may end up hurting them. She also says that if Miharu wants to come to Haruto's side once more then there is one opportunity to do so, when he revealed his true identity and told her to not run away if that opportunity came. Thanks to Satsuki who gave Haruto advice, he can now accept himself and Miharu once again. She later tells Sendou Takahisa that she is in love with Haruto as his past self and as Rio, Takahisa attempts to kidnap Miharu but Rio came and saved her.

Personality
Miharu is a soft and kindhearted girl, sometimes even too kind for her own good. She ranks #1 in her middle school's list of girls the boys want to marry, in addition to the list of housewife-type girlfriend. She's a caring person, honest and responsible, and seeing her still fulfilling her promises shows she's a really loyal girl. Aside from that, she's also very shy, not good at interacting with boys, and known to be too forgiving.
