Abilities/Powers: Kamui is part of the Yato Tribe, a warrior race of aliens renown for their ability to inflict carnage. There are some qualities unique to the Yato:

STRENGTH: The Yato are, firstly, immensely strong. The extent of just how strong is uncertain, but Yato have been seen decimating large statues with a single punch. Kamui is no exception. A punch from him can easily shatter a regular person, and he has been seen destroying large ships single-handedly.
SPEED AND AGILITY: The Yato have an above average speed and agility. Kamui has been seen dodging attacks in a split-second, so quick in his movements that it can look like he had appeared someplace else to the untrained eye.
HEALING: Accelerated healing is another unique quality to the Yato body. They also appear to have a limited regenerative ability (for smaller appendages like ears). Kamui, for example, appeared fully-healed a few days after being impaled in the back by arrows. Also, while it is unclear if this is a unique quality to him, substances like tranquilizers appear to have a delayed effect on Kamui. After being injected by elephant tranquilizers, he was still able wreak carnage, killing a dozen or so men before finally succumbing to the effects.
INTOLERANCE TO THE SUN: The planet that the Yato come from has been described as a dreary one that always rains. The Yato are, therefore, not adapted to living in the sun, as their pale skin shows. If not hiding under the shade or fully covered up, prolonged direct sunlight is likely to burn them. It seems that the more exposure they have to the sun, the better their tolerance to it - as shown by Kagura, who is regularly seen walking around without her umbrella. The less exposure they have to it, on the other hand, the worse their tolerance to it. If a Yato were to go years without going out into the sun, for example, their skin will dry out completely and they will die.

Items/Weapons: 2 sets of clothing (his changshan) and an umbrella.

VIDEO/ACTION;

[ The network flickers on, and at first there's only the image of a single lock of orange-pink hair that's sticking out of someone's head. It wobbles, almost like antennae. Think that trope with the cute idiot-character and their ahoge, or Edw*rd Elr*c.

The screen pans down, and the phone's owner waves at the camera. He's a pleasant-looking man with bright hair and the palest skin, and he's donned in traditional Chinese clothing (a changshan). For some reason, he's holding an umbrella despite the fact that it isn't raining.

There's a cheerful smile, and the perceptive might note that there's little sincerity in it. The even more perceptive might pick up on the fact that ... this guy isn't exactly someone you want to cross paths with. ]

Hey there. This is pretty weird, huh? What part of Earth is this?

[ In any case, he seems to be taking his own abduction really well. ]

Well, it doesn't matter. The thing is -- I'm starved, and I really don't know my way around the place. Anyone kind enough to be my tour guide?

That North-place is where I wanna go.

Sample Entry Two: (adapted from one of my tags.)

In one of the rooms of this abandoned building that the Yorozuya are going on a rampage in, Kamui stands in front of Kagura, neither of them moving an inch. His sister had broken off from her friends earlier, telling everyone that she was the only one who could deal with this 'Jerk-Brother' of hers, that it was important to her that she did, and that they should move forward without her. They'll go back together afterward, that girl had said, before plunging herself into battle. With those hopeful, determined eyes, they might have had it difficult to refuse.

And it's evident in the sorry state of the room that there had been a battle in this place - not any regular kind of battle, but a battle between two beasts. A wall had crumbled, and the other walls have dents in them the size of small fists. There's debris lying everywhere - glass, ceramic and wood. It might have looked like some sort of tie at first glance, with how the both of them are standing and there's a deathly silence filling the air. If one should inspect further, though, they'll see something poking out of Kagura's back, and blood searing out of a wound that had impaled her.

Kamui's hand.

"It's too bad that it had to end this way, dear sister. But you attacked me, you know?" He starts slowly, a calmness in his tone that can only suggest complete nonchalance. Sure, this was the sister he had lived with, broke bread with, braved the situation of poverty that they were born in with, but all that is long behind him. He dislodges his arm from inside her, not flinching once at the feeling of his own sister's guts. Kagura's body topples, still the small and delicate thing that it is, and lands on the ground.

"I'll admit that you got stronger," He continues, and it's not an insincere compliment. A lot of the blood that's soaking his white clothes is his own, and he can acknowledge that. However --

"But you're still the same as you were then. Weak."
