press space tomorrows project: ranking hashira by flexibility
my ranking on hashira based off of their intelligence. 9. tengen is obviously the stupidest hashira and the entertainment district arc is proof. he tried to get aoi and naho to go the entertainment district and then spanked aoi for not going with him! he doesn't care about much, just his wives and being flashy. 8. mitsuri isn't the smartest but shes smarter than tengen. she doesn't act with a lot of smarts and depends a lot on other people such as tanjiro and obanai. 7. rengoku is only smarter because he trained mitsuri. he knows flame breathing well, but that's about it. 6. muichiro had memory loss for a while and he has a very short attention span unless he is fighting. but he's much smarter now that his memories are back. 5. sanemi is a hothead and very arrogant. he doesn't act with smarts, he acts with force. he has good battle iq, but in terms of actual smarts he's not much smarter than muichiro. 4. obanai is smarter than sanemi due to the fact he knows when not to talk and when his thoughts are needed. he also has much better battle iq and strategy. 3. giyu is about the same smart as tanjiro is. he's quiet, stoic and also a good sense of justice. 2. Gyomei is the 2nd smartest due to the fact he knew everything that was going to happen during the hashira training arc. he suggested the whole thing and everyone agreed with him on training all the members of the Corp. he also helped kagaya with exploding the mansion and beheaded muzan. 1. shinobu is the smartest due to her being the resident doctor of the demon slayer corps and she knows more about injuries and poisons than anyone in the entire corps. her knowledge of poisons and medical needs make just a bit smarter than gyomei, but it can be interchangable depending on who you ask.
