A bit random but, I just realized that the overall reception for this manga is much bigger than what I thought.
Everywhere you check the available volumes not only have a high amount of reviews (Especially Amazon, where it rivals and surpasses even popular Shounens) but the overall rating is also really positive. On top of that, the Kindle edition of the recently announced Vol 4 is frigging Top 2 in the
Graphic Novels Bestseller List, only surpassed by the also recently announced Made in Abyss Vol 12. (By the time I'm posting this)
Also, this keeps getting more and more popular on the YoungChampion website, where it has more than 80k likes (It seems the only manga that surpassed it is the ultra popular "The Dangers in My Heart", but I don't exactly use this site)
To be honest this comes as a surprise to me because the reception for the LN isn't even close to this.
It wouldn't surprise me if this (Well, the LN by proxy) gets an anime adaptation in the nearby future.
(Of course, until we have actual sales numbers, it's hard to tell how popular it actually is, but from what we have, this 100% seems to be a hit)
