Shinigami wa Korosenai
I'd prefer it to be longer since there wasn't much time to develop the lore (like okay, there's 3 shinigami levels, but what does that mean?) and their relationship (it is what it is). And Connor was just there to tell the MC the truth; I liked Connor's design and would want more to his character. Does he really care about Caleb? (he does; but again, why and how? Lore said shinigamis don't have feelings (which in Caleb's case, I'll interpret as him getting feelings due to his corruption)) Why does he want to get promoted? What does it even mean for him? (Again, nothing was mentioned about the shinigami levels) I could ponder on and on about what could've been, but I'll get nowhere because this is a completed manga. And even if it got a sequel, it'll be a bit late for that.
