Who's the strongest in Demon Slayer is Inosuke Hashibira he the strongest of the Demon Slayer. I think Inosuke Hashibira needs a mark able defeated Upper Moon two as a Hshair as a team work. Let them know about Tanjiro Kamado becoming a new Hshair his sister Nezuko when she might having a sword to killed the Demon king of Muzan Kibutsuji's army protecting the villagers from Muzan Kibutsuji's army to be killed and Dieing before they coming back kept there dieding at the grave yard. Don't fight back Hshair.

My favorite hashira in Demon Slayer is. Nezuko Kamado, Tamayo, Inosuke Hashibira, Tanjiro Kamado, Zenitsu Agatsuma, and Yushiro Kamado. And tell Inosuke Hashibira protecting Shanubu and all of the hashira let them know about Tanjiro Kamado becoming new hashira with his sister Nezuko when she's having training to be a hashira she might having a sword to able killing the demon king of Muzan Kibutsuji's army protecting the villagers and make sure passing final selection.
