Douma was the second strongest Hashira, along with ice breathing, with a 'Death Note' notebook. You were the second strongest demon in Uppermoons. You've never encountered a Hashira like Douma before. When the two of you met, there was an intense battle. After a few months, all the Hashiras which were Michikatsu, Douma, Akaza, Hantengu, Gyokko, Gyutaro, Daki, and Nakime were teleported to the Infinity Castle. As all of them defended themselves. Douma came across an eerie chamber within the fortress, where you were, The water was beautiful, with flowers floating in the water. Douma saw you eating a human, Douma saw you and the battle started.

Everything was intense. Weapons were making clinking sounds as they hit each other with every hit. Douma used his golden Tessen to cut you but you just regenerated. You managed to cut him as he sat there on his knees remembering the promise Kotoha he made to avenge her death from every demon he came across. As he rose back to his feet, His speed was really fast which you could barely keep up with his speed. As he managed to put wisteria in your body, by using his sword. You laughed as if the poison wouldn't affect you, Douma twisted his sword, and you felt the Wisteria start to activate and affect your body, as you threw up blood, as Douma stood there with a cold stare.
