I'll kill him…

The stillness of the park was disrupted as a large flock of birds scattered into the air at the sight of the black blur that shot through the trees.

-Whoosh-

Chikusho…how dare that baka propose to my sister!!

Hiei's eyes began to glow a dim red, and his top lip was pulled up into a snarl as his right hand gripped the hilt of his katana tightly, his knuckles white. Pressing his left foot against a tree branch, he pushed off of it and jumped to the next tree, using his right to leap even further as he skittered through the park towards the street.

His ears picked something up and he stopped, sliding his katana slightly out of its sheath with his thumb as he looked downwards. Two humans, a male and a female, walked under the tree he was in from the sidewalk into the darkness, clasping onto each other's hand as if it was all they had. The fire demon snickered and rolled his eyes, growling quietly in the shadows.

Hn…Nigen emotions…Pathetic.

From under his headband Hiei felt his Jagan open, and he flashed his eyes over to the roof of a large building. Ah yes, that's where the nigens went to school. Smirking to himself, he bent forward and reached across his waist to grab onto his katana again, closing his third eye.

Prepare to die, fool…

He quickly leapt to another tree, then up its branches to the top, peering through the leaves.

There he was. But, wait…Yukina was with him!!

Hiei's anger flared and he closed his eyes, gritting his teeth together as he fought to keep his ki from growing; he did not want to be spotted before the opportune moment.

What is she doing with that human? There's no way she could actually want to be with, him

- -…Hn, you're so stubborn Hiei…Your sister is happy, and yet you won't allow yourself to admit it- you're just jealous that the idiot is getting the love and attention that you've never received…aren't I right…- -

Grrr, shut up!!

Hiei had to force himself from slashing wildly at the air with his sword in frustration, also wary of keeping his balance atop the tree.

Darn it, what was he thinking- of course he wasn't jealous of that fool. He couldn't be jealous, there was nothing to envy when it came to Kuwabara. Well, height perhaps, but that was definitely it. He was smarter, stronger, faster…so what was it? Was it really that he was resentful of that nigen because of his sister's affections?

It was true nevertheless, Hiei did think that he deserved his sister's love far more that that baka did, and yet deep down he never really thought much on the issue.

"It matters not," he said aloud in the silence, looking down at his partially unsheathed blade. "I will kill him now, and get him out of both of our lives for good."

With a slight thrust of his legs Hiei shot up into the air faster than even his own eyes could keep up with. But he did not need his vision, for he could sense the orange ki spreading like a soft fire into the cold atmosphere well enough.

The wind could not catch the fire koorime either, and as his blood flowed like magma in his veins, he pulled out his katana and swung it over his head, slicing it down through the unwilling still air with all of his might until he felt the blade meet its target.

His feet pressed against the railings for only a miniscule portion of a second, and then he blurred away again, his eyes closed tightly as he ran quicker than he knew he could go across the city's rooftops, the ear-piercing, heart-wrenching scream burning into his mind.

Kami…what have I done?
