I read this, thinking the story would be around a teacher theme like LoHP. So, I was quite disappointed when the system just forced the student to like the MC and the MC didn't teach his other student besides this 'chosen one' student. Quite ironic, honestly. I won't read this if I have other books to read
The system has too many features that are too OP, which only became a plot hole. There's like a daily login where you can (+) attribute directly towards skills/weapon that will develop something like sword intent, saber intent, so you can basically learn anything but until 353 he was only a sword immortal.
