I think Touka won't come alone too... it will be dangerous for her as well
What I'm hoping is... Satsuki already ready for another prey
and Shiinya will appear at the end of the teacher's life to deal a finishing blow... or at least just look at him with his sharp eyes
just recently read this manga... I hate the genre actually... but to think that there is a harem consist of yandere girls... I think it's a very good idea and plot
