@Lambdadelta_Umineko Oh no, don't say sorry, i'm the one who should offer you an apology, sorry, how could i forgot about real life problems... thank you very much for the chapter and if you are working with someone then thank you all for this.
Isekai usually implies another dimension unrelated to the protagonist's. In this case, it's "just" the netherworld, not a more exotic dimension with no connections to earth. I can see your point, though.
