🔥🗡️DEMON SLAYER "S1E12 "The Boar Bares Its Fangs, Zenitsu Sleeps" (EP.12 FULL REACTION)

So Marechi is a rare blood type like AB and more. I guess the blood type in this anime is a power calorie/protein to enhance a demons blood-art/powers.

Actually 12 kizuki consist of 6 upper moon and 6 lower moon demons while uppermoon are like the most powerful ones

Every demons have MJ's blood in them, it's just the quantity that differs. 2 ways that demons can grow stronger that we know so far is by eating humans or by getting more of MJ's blood, and as we saw in earlier episodes, not every demons can handle the extra blood he gives them, so I assume the stronger they are, the more odds they have of surviving the extra blood MJ gives them. (Also, I'm really sorry to tell you this but the cliffhangers are going to get worse and worse)

they always share some fun facts in the after credits, but like he said, they runned out of time 💀

tanjiro is 15 years old now. Nezuko is 14, zenitzu is 16 and board head kid is 15 also.
