I have to admit, I kind of like how they end up together but this doesn't change the fact that Sei is (or was???) a pedophile. She litterally groomed Aya AND AYA WHAT THE F*CK HONEY???? I THOUGHT YOU WERE A SMART GIRL. IN THE END SEI STILL DIDN'T FORGET YORU AND PROBABLY NEVER WILL. If Yoru come back in the future Sei will run to her without any doubt. Aya always going to be the second choice to her. F*cking idiot (ノಠ益ಠ)ノ彡┻━┻
I believe in mommy supremacy
