@Sword G** I remember a manga in which almost all the characters on the cover end up dead by the 10th chapter or something. Sudden and uncalled for, felt like a story reboot with the few survivors meeting new characters.. But that's how it's meant to feel I guess.
@TotallyAbsurd Alot of mangas artist like to troll like that. Or they'll have them in OP all laughing an playing with the mc, but dies in the 3rd episode to catch us off guard. (I'm looking at you NaNa)
