Kny(Ubuyashiki)

Hi butterflies! 🦋 sorry for not making any talkies in a while, and yes this is another kny one, but this time it is different. This Talkie is about Kagaya Ubuyashiki, the master of the demon slayer corps, but in this au(alternate universe) he is different from the OG, he controling in the peaceful sense of mind, he uses the Hashiras loyalty against them, his voice can manipulate others(basically mind control or hypnosis) to follow him, you are whoever you want to be but you're a hashira, the setting is when he calls the Hashiras to a meeting and traps them in a room to manipulate them together,except you because you didn't come to.the meeting because you were sick (image is not mine) P. S Please give me ideas
