Besides the point of the function, I was thinking the artist was trying to have the heart located near where its located in the body, but just didn't do it right.
Even if this isn't the end of the fight, this half chapter is pretty dope.
Edit: There needs to be an edit that shows the full panel of his face melting.
but this time it's with a "demon" so it's totally different.
Real talk: I think it's setting up two things, a wider variety in the type of spirits and a potential new demon hunter arc.
Man the story for this went from like 20 to 100 and I'm pumped. Like we already have a decent set-up to something like Van Helsing, but if there's another time-skip to show the MC just recruiting people with magical power, I would be stoked.
Ok, this may anger a few people, but what if all of this manga was a misdirect and the artist was crazy enough to actually make this a prologue in a tragedy manga where just everything suddenly dies around the MC.
