1. Hiei is a swordsman, and Botan is the girl and Kimono. Swordsman, Kimono, doesn't it fit together like in Rurouni Kenshin. Kenshin had a bad past like Hiei, and Kaoru like Botan wouldn't care what happend to him in the past.
1.Hiei is a dark and somewhat evil fire demon. Botan is one step down from being an angel. It would seem as though Yoshiro Togashi MADE them for eachother. That, or he planned for them to be bitter enemies, which wasn't the case(or so it seems). Think about it though, a demon and an angel in a romantic relationship. Do you have any idea how kick ass that would be?
2.Hiei only communicates with Botan through telepathy. No one else. Why Botan? Well, I'll let you connect the dots yourself.
3.In the Chapter Black saga when the group wanted Hiei to help them find and rescue Yusuke, he refused. That is, until Botan asked.
4.Again in the chapter black saga, when they were going up the different stairways to where Yusuke was located, Botan tried to put that sticker thing on Hiei. Hiei grabbed her hand and held it for WAY longer than necessary.
5.Once more in the chapter black saga, when Yusuke was trying to determine who was the imposter was in the group, he asked Botan what her size was. Hiei suddenly becomes infuriated at Yusuke, clenches his fists and grits his teeth while shaking with fury, and promptly calls the spirit detective an ass. Why would he get mad over something like that? Again, I'll let you put it together for yourself.
6.Yin and Yang. Need I say more. Niether can exist without the other.
7.Black and blue. Sorry, but I find that kind of funny. No clue why, though.
8.Don't you females all think that Hiei's hot or something? I imagine it would be the same for Botan in terms of what she thinks.
9. Again in the chapter black saga(you getting sick of this saga yet?), when Hiei returns to the group Botan is all happy.
10. In the second Yu Yu Hakusho movie(yay! Finally out of chapter black!), when Botan is hurt and unconcious, guess who's staring at her. If you guessed Bill Gates, your wrong. It was Hiei! he was worried for her safety...........or maybe he was checking her out. Perhaps a little of both.
Reasons from Nikki
well, u kno how the DBZ fans say that YYH is a rip-off from their show? well, that got me thinking and they do hav a point but i digress. anyways, in DBZ, Bulma and Vegita end up togehter as a married couple w/ kids. well, they're equals in YYH would be in fact Botan and Hiei cus they act and look practically the same, no? so yea another reason they should b together is the fact that their DBZ look-a-likes got together. and thats my 2 cents for today. ^_^
