As an Isekai enjoyer, I've read a lot of shitty fantasy manga but this... This is exceptional!! I've never read something this painfully bad before... The worst version of every trope and cliches just came one after another like a conga line.
This guy survived and recovered from getting every organ in his body crushed within a week, her master is some kind of monster himself with how surprisingly durable he is.
A match made in heaven I'd say.
