After "shhhhh" joke in Namekawa I was hoping to see more 4th wall breaks from Atou-sensei. They are of highest quality.
I like how girls find each other cute. I bet they'll become besties in no time. Also, yes, brownie points to rival for indirectly helping our hapless MC. Rockets to start the fire is very good, but this knife thing stands out of place...like totally out of place, on a chapter level.
My fav still the teacher. He, like, reinforces his place in my heart with each chapter he appears in. How did he become the teacher? Obvious: he is the best.
