Alright, I read it a few months ago (don't know when it was actually made, though). Sesshomaru was traveling with InuYasha's group. Every night (I think), Sesshomaru would disappear, then reappear some time later with some sort of dead animal. He'd drop it at Kagome's feet and she would say "Thank you". Then he would leave. His "Gifts" get more and more weird until he finally gives her a dead elephant (I think it's a baby). She's sad that it's dead but still says "thank you". This pisses Sesshomaru off. I don't really remember anything after that. I'm pretty sure it's a oneshot but it might just be a chapter story I read in one go ^.^
Ah! I'm pretty sure it was on this site, too. And I've tried searching "Gift" and "Odd" and the like but still couldn't find it T.T
I know it's not "Tradition" by Sunsetmiko (though this is a good oneshot)
If you don't know this story exactly, but know of one like it, I'd appreciate it if you named it. I don't know why but I like Sesshomaru giving Kagome dead things
Thank you <3
