Firefighter: Omg he’s such a genius why couldn’t I think of that?
Literally all readers: Why aren’t you able to think of using the door?! Surely that room has a door?!!
Note: Firefighters carry compressed air, which is not pure oxygen.
It’s really a nice shoujo manga.
The rating on this is ridiculous. Based off the general ratings on Mangadex, I would expect this to be about 8/10. The art and design is better than average to be honest. The translation reads smoothly. The plot is shallow, just like what you would expect from...
What exactly does he plan to accomplish with that bucket of modestly-sized rocks, against the dude with a sword? Friendly match of improvised baseball? At least he can use the bucket to protect his head.
I think getting knocked out reduced his IQ by 20 or so points. Minus another 20 for receiving an attack with his head. If this guy gets hit another couple of times, he would become a vegetable from the accumulated brain damage. Maybe I'm not getting the point?
Let's just take a moment to appreciate an unconventional and novel first chapter. The plot, though simplified, appears logically sound and intelligent for an isekai. I wish I had the will to properly learn to read the Japanese LN!
I also really like how Kirei Cake translated this. It feels...
“Don’t tell me it’s unimplemented...”
“Then what about the OTHER TWO???”
This is literally the dumbest line of thought I have had the pleasure of reading in my entire life.
