Dialog yang dibuat only for the sake of audience gitu? Yang pas ribut, tiba-tiba ada bilang baik langsung atau dalam hati,

"Hah! They can't do it because my neck is strong!!"
"After they fail because my neck is strong, I'll crush him!!"

Lalu, yang demon swamp flashback ke Muzan larang dia bicara, probably dibuat dia kelihatan takut aja udah cukup but they went ahead and make a scene of Muzan telling, "don't tell about me" gitu.

For the amount of blood n death, I don't think that their target audience is the younger ones? Tapi kayak dibuat untuk kapasitas nalar anak-anak gitu jatuhnya.
