Well, Havoc, there's your confession from Kanna. It didn't do much for her, other than relieve her of some tension. And now we have a new (and more potent) rival for Ichika: her own sister. I wonder if he can convince her to stay on Earth as well...
Tetsurou is stuck between two girls: one loves him, the other does not. He loves the one that doesn't love him, not the one that does. It's going to take a lot of effort to get that mess straightened up.
And Lemon is becoming more and more interesting. It was clear she was onto Ichika's game from the start, yet she still supported her.
