Guys, give Io some credit, she's been through a thousand times worse. Obviously she's not fine, but have some faith in her.
I am impressed she went to the beach trip though, I was not expecting that. I wonder if Uta forced her? Or maybe she's still into her idea of "I am a fuckdoll for Akira now and thus must be here". I'm interested in her reasoning (and to which degree she's heavily medicated to be there - or even more worringly - if she's not medicated at all).
I also wonder how it will pan out for Uta and Akira with her being there... since we were predicting a sex scene for her. Maybe instead of a sex scene we'll have Uta telling her how happy she's with Akira, and I also wonder about Io's reaction to that one.
