Got to love the people talking about a 36 year old hooking up with a teenager. That's not even what's happening. The young girl has a massive crush on her teacher, the teacher still has feelings for her mother, quite frankly Kusanagi-sensei isn't interested in her student currently. Kuzuki just reminds Kusanagi-sensei of her mother, there isn't anything wrong with their relationship. You people act like Kusanagi-sensei is making advances and sleeping with her, yet the majority of the time she's lecturing the poor girl. Lmao.
Seriously, cool your jets the author has already clarified that they don't end up together until Kuzuki is old enough. Knowing Kusanagi-sensei and her serious personality, it's not happening until AFTER Kuzuki is out of College.
