This is another recycled from MyO post section, but I'll put it up for discussion here for any interested ^^ If it goes over well, I may add one up on Hiei's father ^.~

Now in my extensive research and observation of the YYH series, I have developed a new theory ^^ Now one of the many wonderful attributes about Kurama that I love is his sense of modesty. Now every other guy on the team either throws the top of or his shirt gets disentigrated…but never Kurama. “I’ll get that arrow for you pretty boy, and I’ll do it with my shirt on!” In fact, we only see Kurama in long sleeves on top of that! Looking closely though at the pictures that swirl around in the 4th ending (“When my letter reaches you, please don’t break the seal…”) and a few of those pictures Kurama actually is wearing short sleeves! These pictures have the “everyday” sort of feel to them, you know when everyone isn’t facing danger and holding the fate of the world in their fist. I have come to the conclusion that Kurama must have something special he lines his clothes with to withstand energy blast, making his clothes a light-weight armor. Now blades can still rip the cloth, but blast are deflected. Watching on to where Yomi’s ambush with the lower demons, Kurama uses his backpack to keep one of them from hitting him—and the backpack comes out of it unharmed…so it must be lined with that special something as well. And then later when Shura blasts Yomi and Yomi emerges, Koto announces, “I’ve never seen anyone walk away from a blast like that with their clothes still attached, much less the rest of him!” So Yomi must be in on this little fabric secret too…‘ancient demon thieving secret!’ ^.~
