I dropped this story for about half a year, and coming to read it again now I realized that I really was quite lazy with the execution of the story. I was planning for the mc to separate from rimuru and go on his own way after this fight, but I realized that the world of tensura is bigger that I thought when I watched a recap to volume 11 of the LN I didn't know how to complete the story. I started this as a fanfic thinking it is easier and I don't have to do much world building, but in the end the world building of the original became my downfall. Do you think this could still be saved or should I start over? and thanks for the comments.

I forgot that they are called kiijin In Ln, but thankfully it translates to oni people so it is not that far 0ff.

I will make an auxiliary chapter describing him and his STATUS when he gets his Zanpakutō back.

Soon, one of the ogres is a blacksmith specializing in Japanese swords, and he has the unique skill researcher to help make a asauchi.

I thought the same thing, I didn't come up with the name thou, he's an original character.

He doesn't know about Tensura, He transmigrated to bleach before it even came out, So after seeing a slime and magic he thought that he just in a RPG Fantasy themed world, He also doesn't know that rimuru is a protagonist although he will guess it later.

The MC just followed rimuru's soul when it was passing between realms in order to find a way out, He is not directly connected to rimuru at first as rimuru soul was guided by the world's system so it was reincarnated as a slime, while the MC unconsciously condescended a spiritual body by himself, he is a shinigami he has experience with spiritual bodies
