Hashiras React To Blue Exorcist // Gacha React 

Yeah, technically speaking muzan is only on the level of a demom who possesses a person, only reason he's so strong is the thousands of years of blood harvesting he has done, he's canonically done enough to actually get tired of drinking blood tho i do personally believe he's stronger or equal to amaimon, mainly due to his kill switch and the fact it took 3 different poisons to weaken him to the point where tanjiro could actually do damage, one of the medicines making muzan basically go through 3000 years of starvation, which would be his actual major weakness, he also had enough poison to turn a normal demom into a human and its probably part of what attributed towards tanjiro becoming human, as tanjiro bit nezuko, who still must have had some of the factors that turned her human in her body, muzan ONLY lost because in my personal opinion the poison hindered his thinking, muzan was known for being extremely intelligent even more so as he gave himself more brains, yet he seemed dumbed down during the fight with tanjiro, it could just be a plothole, but in my opinion, he wasn't fully in the fight due to having his focus split on neutralizing the multiple poisons while being weakened by them
