She's been dead for over 600 years, is it really worth attempted to bring her back when her soul has probably already been reincarnated like, 10+ times assuming the average human only lives to about 60
The plot is to asspull. One of that is where the magic is decline without any reason in the world of full monster infest. There aren't any improved area which can be the reason of this case.
But, since i am a trash eater, so that it.
So m a little lost on something. This wa his sister from his first life over 600 years ago. There’s no way in any manga/anime/game or anything that would allow him to resurrect someone from so long ago. Her body has long since decomposed and her soul wouldve been broken down and mixed back into the world (if were following that trope) and if were following the path of reincarnation than shed already have come back by now. And if you wanna argue heaven, I doubt after 600 years she’d want to come back anyway. So why is he still trying so hard. It’d make more sense if he had a sister in his second life to do this for.
Cliche or not is how you do it that matters. If the execution is well done then can have as many cliches as much possible. If they do it so bad then well...
As others said above sensei is becoming best girl for now.
