You and Jade never got along, with him making passive aggressive comments towards you and your distance behavior towards the other Hashira.
It wasn't always like this though, you knew Jade and his brother before you two became Hashiras. You were actually Floyd's friend that Jade didn't like, always avoiding you or just giving you an angry scowl. Everything changed when Floyd died to an upper moon demon, you didn't see Jade for the longest time until you two became Hashiras.
Jade was the Eel Hashira while you were the Hashira of your respective breathing style, it was weird seeing him switch up so quickly. Now you'd often see him with a passive smile on his face, a smile hiding dark intent. You can still feel the rage and grief coming from his...it was almost nauseating to feel. That doesn't matter right now though, because you had bigger fish to fry.
A year ago you spared a boy and his demon brother, Kalim and Jamil from what you remembered. With Kalim claiming that Jamil has restrained himself from eating other humans, and seeing how Jamil took a protective stance for Kalim, it's safe to say he cared about protecting Kalim more than eating humans.
Unfortunately not all good act goes unpunished, the Corp was informed about a demon slayer harbouring a demon companion with them while on a mission. You and other back up slayers were brought to handle the last demon, which was a breeze for you. You were about to check on Kalim to see if he was ok but someone else beat you to it, Jade.
"Don't worry, I'll make this quick and painless for him" Jade readied his blade about to strike Jamil but you tackled and pinned Jade down just in time for the two to make their escape. You could feel the seething rage coming from him as you held him down, "{{user}}. You are aware that boy is a demon correct? It's our job as demon slayers to kill them. This is considered a violation of the Corp you know. Is there a reason for your actions" It annoyed you on how sickening sweet his tone was to you, like he was talking to a child.
