"Nooo Usato, you can't just use bloodline magic like that, you'll hurt yourself"
"Haha, mana go boom"
Leona seems to have forgotten she was talking to the madman who dislocated his own elbow to get out of a hold.
Calm down, the author literally just course corrected away from a pointless love triangle, turning the love rival into a wingwoman with a threesome agenda. No NTR here.
I think we're introducing too many major characters, too quickly. One per chapter is just way too fast, there's no time to develop the relationships between the existing ones.
Especially considering how few pages we get each week.
For fuck's sake, this here is the narrative equivalent to just half of a yonkoma, and we have to wait until next week for the punchline!
If all it took to take down the barrier was digging underneath the wall's foundations to cause it to collapse, wasn't there a more practical method to doing so than that magical Big Bertha?
Sir, this is an ecchi manga. There are no psychiatrists, and even if there were, they'd encourage that relationship for an absurd and contrived reason.
First the girl jealous of her younger sister stealing the hot bishop's attention, then this... it seems as though Sensey is on a quest to find the best, most harrowing NTR story.
Rough transcript of Sagami's thought process this chapter:
Awww, hug!
Oh no boob press! Retreat!
Oh no I can see boob! Need to hide boob! Tactical hug!
Wait, I'm pressing boob again! Wat do, Musubu?
Yeah, good idea.
How could I possibly say no to a harem of sexy teachers?
Side note, I think the author's style works much better in this than Renai Flops, it's a better fit for depicting adult women.
