Honestly, it's not terrible. That doesn't mean that it's good, just not terrible. The art is ok, panels aren't overcrowded/too detailed to make out whats happening. The mc has kinda unique abilities, but isn't insanely overpowered. The fight choreography is bad, and gives the fights no sense of tension or danger, which causes boring awkward looking scuffles.
Oh, and to praise this manga for something that pretty much no other isekai does, THERE'S NO FUCKING LOLI HAREM!! FUCKING FINALLY NO GOD DAMN PEDO MC!!
