For me they would be perfect for each other, They're like Inuyasha and Kagome 2.0 for me. Look at the description of this YT video :) link

She's best off with Kohaku, Sesshomaru needs someone that wont be dead in 30 to 50 years :P

I think she would fit Kohaku more.

Sesshomaru and Rin have a father-daughter relationship but Kohaku and her could sprout something more.

The majority that picked Sesshomaru are all pedophiles -_-

^ WHEN SHE GROWS UP!!
Asshole -_-

Sesshomaru is like Rin's father figure/protector. It's just sick to think of them as being together. Kohaku is ideal in my opinion.

How about Rin and Kagome's little brother Sota?

Kohaku. He's good with Rin ^^

i choice SESSHOMARU AND RIN ^^
SESSHOMARU AND KAGURA NEVER
RIN AND KOHAKU NEVER

I saw Rin with Sess most people try to figure out if she's not there, then Sess sure what became the idol of the people, Rin she had touched him, melt the icy heart seemed he will forever freezing of Sess, because Kagura Sess met last time you said Sess merge with Kagura is why? Just because Kagura equal age with Sess? Just because Kagura same species with Sess? This is ridiculous !!
and for I LOVE NO AGE DISCRIMINATION, What a day old and Rin will die but for me it does not matter, their love for each other is eternal, forever the world!
