Walking home from school one day, Oikawa comes across an abandoned kitten. Deciding to take the kitten in, Oikawa takes it home only for it to vanish the following day and some unusual things start to happen... Sorry guys, this one is pure fluff!

I am friends with Tamaki Suoh. Some may even say he's my best friend. But I am only friends with him because it benefits my father, which then benefits me. I do everything he asks, even if it's absolutely ridiculous. Now that I think about it, he's the only one that can get me to do ridiculous things. But that's only because he's so important. To my father, that is. That's the only reason he's my friend; though I find myself repeating it over and over until I can believe it. People have told me that it's because I'm in love with him, which I find absolutely absurd. However, if it were to be true... I suppose... I'm lucky to be in love with my best friend. A/N So if you didn't realize, the description is in Kyoya's POV. However, the story will be in third-person. Also, I got the inspiration for this story's title from the song "Lucky" by Jason Mraz and Colbie Caillat.

"I won't ever hurt you... Not on purpose anyway. If anyone tries, I'll make sure they'll regret it." Kaigaku's eyes widened in surprise when he felt Zenitsu lean into his protection and return the hug. The back of his kimono started to become a little damp as his brother cried into his shoulder. He couldn't bring himself to care. A strange feeling pulsed in his chest when he realized that he had made Zenitsu feel safe enough to be openly vulnerable. Safe enough to show his emotions without getting hurt for it. "Thank you... Aniki." Basically a Good Kaigaku and more intensely traumatized Zenitsu AU. I'm not sure how far into the actual story line of Demon Slayer this will go, considering I have only watched the anime. Disclaimer: I don't own Demon Slayer The cover art is mine.
