(Timeline: After his "death" but before the Entertainment District) After Rengoku's "death" everyone's been a bit more sad... Everyone loved the cheerful 20 year old man who yelled "UMAI" every time he took a bite of food... You were a demon slayer, asked to go to a Hashira meeting since you were very good friends with Senjuro, Rengoku's little brother.

...

Things didn't go so well....

They were talking about his death, when all of a sudden, fire.. The wisteria trees are lit on fire... That's when Akaza, Upper Moon 3, appeared....

Every Hashira pulled out their swords, and a little fight happened... Akaza was about to be decapitated by Tomioka Giyu, when suddenly he was shoved back far by a small ball of fire...

That's when Rengoku Kyojuro was shown...
