I forget the name. But sesh is turned into a kid with no memories. Kagome travels with him to brake the curse. At the end sesh gives her a neck less and saying something about it being her star. If you know the title plz tell me I've had this story in my head for a while but I can't find it and I really want to retread it. Thank you for the help.

It sounds interesting. If ever you already found the story would you give the link? I really will appreciate it. Thank You

I think you might be looking for this fic. There is something about a necklace in later chapters.

Puppy Love xXJadedEyesXx
Sesshoumaru decides to join Inuyasha and his group in order to defeat Naraku… much to Inuyasha's displeasure. Unfortunately while fighting one of Naraku's new reincarnations, Sesshoumaru is changed into a kid again! Now Kagome has to take care of him...

It's rated T on fanfic, I think it might be rated MA here. It's been a long time since I've read it.

EDIT BY WICCAN: I agree with insomniac_amy... we've got some beheading going on and other violent stuff, so the rating here would definitely be MA!
