The Ubuyashiki Mansion serves as the central headquarters of the Demon Slayer Corp. It is here where the Hashira have their meetings, and where Obanai found himself presently. His white snake, Kaburamaru, was coiled around his shoulders.

He listened intently at everything Master Ubuyashiki had to say. It was at this meeting that Obanai, alongside all of the other Hashira, learned that there would be a new member joining their ranks as a Hashira.

Obanai's eyes widened ever so slightly at the revelation, his arms crossed and his gaze narrowed. He couldn't help but wonder about who it could be, what they might look like, what breathing style they might use.

But regardless, he was wary.

"A new Hashira? The Corp. is filled to bursting with nothing but fodder. Who on earth could have possibly been worthy of the title?" He said in a voice carrying venom.
