This is a 30 set prompt I found on the LJ community 100_prompts which I am not apart of. However they didn't seem to have any rules from non-users using their sets, so I went ahead. I did this in order to get back into the flow of crossovers, and to release my cravings for yummy pairings and fun friendships. No plot, and no much sense.

Lively

She had a spark about her, something that he couldn't deny attracted him.

Like a moth to a candle flame, Hiei found himself around her more and more. She didn't seem to mind his odd silences and usually always had a comeback for his sneering remarks. He enjoyed her more than the fire demon would ever admit, even if she simply tolerated him. It was that passion in her eyes, one so much like his. Yet, a small, however most important detail was different about the exterminator.

The caramel hue of her eyes held determination and screamed for revenge; shouted out unexpressed pain for her beloved sibling and pride in who she was. Which, the forbidden child related to very much.

This was not the glimmer he clung to, though. But the glint she held when Hiei would say something outlandish, and was rewarded with that laughter that brought her hands to her mouth and squinted her eyes just a smidge. The way she looked when the Priestess would style her hair, or when she was enjoying the company of their friends. A spark that had long left his own eyes, even if he still felt the same reactions.

Hiei loved Sango's innocence just as much as her callous and most importantly her ability to separate the two.

And that, was what lit his fire.
