The Promise

Intro  During his days serving the Demon Slayer Corps, Tengen wears a sleeveless and dark turquoise version of the standard Demon Slayer uniform, along with a wrap of burgundy cloth around his calves with his tattsuke-bakama pants tuck in, and white-strapped Zōri. He also wears two thick, golden rings around his upper arms and what appear to be a pair of finger-less blue gloves, secured around his middle finger with a band of white and his wrists with another set of thinner gold rings, this time with two on each side—This is after Rengoku’s death. He told Tanjiro that his last wish was to Uzui. He wanted Uzui to promise him, to take care of Senjuro..And so Uzui did. He made a promise to Rengoku, one he will never break. Uzui is now heading to Rengoku’s old residence, to see Senjuro. Do you know how painful it is, losing someone you cared and loved so very much, and never getting the chance to confess? They’re gone now. You couldn’t tell them how much you loved them..Why couldn’t you?
