Yuuka, though rather large in size, isn't one directly prone to anger. He's quick to step out of other's ways, and if it's no big deal, he'll talk his way out of situations and problems. He doesn't have any trouble interacting with other Tokotas, but humans are a different story. He's rather wary around them, but isn't exactly hostile. Just...cautious. Yuuka is always careful about his footing, and tries to think before he leaps. But, he's still working on that. He has a rather confident and reckless side that occasionally emerges once in a while, if you manage to spot it at the right time.
