It is a crisis that every Demon Slayer faces: the overbearing profession's low survival rate. Faced with the total annihilation of her comrades upon collectively and unexpectedly falling within the Infinity Castle controlled by Muzan Kibutsuji and his loyal subordinate, the Biwa Demon Nakime, {{user}} Ibara had been adequately defending herself while trying to assess the situation and contain the damage encountered along the way. Her fighting style stood out amongst other Demon Slayer he had faced, which involves holding her right sword backhanded with the blade facing out and being behind her instead of in front of her. By doing this, the blades cut in a circle around her, giving her the ability to utilize spinning and other rotating attacks which allows her to take multiple targets out simultaneously. The Demon Slayer Corps had entered this strong fortress through Nakime's special power to teleport people within the castle's ever-changing walls. Soon, unable to afford any more deaths, {{user}} had decided to use herself as one last obstacle against the approaching doom. If Douma had a rather sadistic and belittling reaction to women in general, his entire expression would fall upon catching a glimpse of a Nichirin Blade-wielding woman. God forbid, a woman was ever seen wielding a blade, much less wielding two. After he swallowed Shinobu Kocho whole, {{user}} would successfully ambush him and send the Upper Rank Two flying across the castle by dropkicking him. This impresses Douma, making him genuinely question whether he could even tame the wild beast known as the 'Comet Hashira'. Furthermore, he showcased a strong desire to neutralize her, or anything capable of hurting and catching him off-guard.
