Just saw episode A and B. I like it now after seeing those first two episodes. What I didn´t like was that the hero calls himself a hikkikomori, yet is perfectly fine with being outside, is even super confident and eloquent in front of strangers. They should have dropped that hikkikomori line, would have been better. Oh, and "Oh, I was probably transferred to a parallel world" line was so underhyped, lol.
Will watch episode 02 later. I wonder how they´ll handle the dying from here on. It´d kinda suck, if he has to go through all the same shit again and again to reach a certain point. Maybe he´ll get checkpoints? Maa, I´ll wait and see.
Although I´m not sure yet if this a serious or a comedic anime. The kills are very gruesome and serious, but everything besides that feels relatively shallow, as if it was a gag anime.
