Is she the FL? I feel like that would make sense because Blue Spirit is the only girl with the most screentime with him. And any other girl wouldn't amount to blue spirit at this point. But she is literally too old for him so if this new character (which also appears to have good Chemistry with mc) fuses with MC, I think it would make sense if they end up together
She and the blue spirit will fuse together or something? The thing is the girl will have blue spirit’s memory and all.. By the way.. I am so happy that this is not a harem like Nano machine.. Mc literally said to fl that he rather die than live without her.. (▰˘◡˘▰)
