I love reading this manga. I would add this to my reading list hands down

I think the LN for this one ended / stalled at just the four volumes. Author in the Afterward suggests checking out the web novel.

@Terrence @Terabyte I can tell because the author said so in Twitter. The problem is, however, there is a teaser of Volume 19 via Amazon Japan and it seems Hiroto and his allies need more than miracles to survive another ordeal. It seems to me that

Here is a description based on a teaser itself, here goes.

Here is in my view based on the the teaser description itself and...yeah, Hiroto and others are in big pinch in this one and you know what else is a stinger? Volume 18 is only Part 1 of the new arc, and Volume 19 is going to be Part 2 for the said new saga and this could be either the conclusion or the climax of the new saga itself.

Man, if you ask me how I feel about this, I'd rather have that part 2 written in Volume 18 as well...

This could tide us over in the interim while waiting for new Realist Hero volumes to be published in Japan.
