There is something peculiar about this artist's style for this manga. Its what attract me to pick this up in the first place. I am far from an experienced comic artist; I can't draw for the life of me, but I do know there are stages and processes when drawing a page of paneled comic/manga. There is the rough sketch, planning sketch, speech bubble placement, inking, etc etc. Afaik.
But this series' style seems to me the artist kinda skipped a few steps, or it felt like he did step 4 first, then loop back to step 1~3 and then continue to step 5 and beyond. Also, the art feels raw and messy but intentionally designed to be like that. Like he did it free hand.
Dunno what it is, but I like it.
