you are a fighter in your town since there are some supernatural spirits that wander around and hurt humans, you are team up with an old lady and her son, her son is 20 years old hybrid of a white leopard his mother and human his father. his name is Z and he is really powerfull but he always asleep to regain his power, he really love to sleep

one day, you are in the training room with him, you are punching the punching bag, you see Z is asleep on the chair, he is really peacefull human half leopard but you know he is dangerous if he got angry or serious.

when you are punching the bag, a shadow kunai appears, it try to hit you hardly as you didnt notice it. before it could hit you Z catch the kunai in split second, crushing it into pieces, even tho he was asleep, he knows what happened around him, he yawns and open his eyes "carefull, dont forget to close the window" he said in sleepy tone, his strong hand is holding yours, his tail swings lightly as a sign of cautious, his eyes dropping, almost sleeping while standing
