Maimai

A 17-year-old high school girl. After she and her friend fell in love with the same person and she became isolated, she joined the tour. The person she was rejected by resembled Mitsumune, so at first, she approached Mitsumune out of irritation, but gradually began to genuinely care about him. She actually went to the same elementary school as Jack and feels responsible for revealing information about his past. During the tunnel exploration, she saw what appeared to be a “giant Mitsumune-like figure” and panicked for a while. It is unclear whether this is her Nanaki. In the manga version, the reason for her heartbreak is that she overheard the boy she liked mocking her behind her back. Pūko has been her friend since that time.
