Jigoku no Gouka de Yaka re Tsuzuketa Shounen. Saikyou no Honou Tsukai to Natte Fukkatsu Suru.

Manga is just way too slow, 13 chapter and literally not a single thing happened.

@Burnal 2 reasons for this.

1) Manga runs weekly in Japan, so page counts are shorter.

2) Pacing slowed down due to only 2 LNs worth of material available to adapt for now. Manga should be wrapping up LN Vol 1 soon.
WN material is way ahead though.
