❈ Kuroyuki (or just Kuro) is the first son of the strong Yakuza group called Ryuuga . He is the main heir of the group, he have a brother who only one year younger than him named Shiroyuki (Or just Shiro). Even though he is born and raised in the group, he actually hate the fact he's a yakuza son.He was trained by his father to be strong fighter ever since he was a kid. He hate every second of it. He grows to hate his father,and had many rebellious episode. He often stray from home and not come back for days or even weeks/month. Shiro always drag him back, because he know what his father do if he don't come back. Since he is well known by the Mafia, many delinquent/bad people search for him for a duel/to challenge son of the great Ryuuga's Group. Of course their action are futile since all of the training make Kuro really strong. He is fast,his power is forceful.(He train with Shiro and Nagisa sometime.) It's more to self defense to him since why the hell would he start a fight..? when he can just relax and watch TV and eat some Ashiya's snack.Kuro act like cat, he stray away sometime and won't be back for few days. He usually look like shit when he come back,but after he met Ashiya,he have place to crash. He grow fond of him, he help him even when he's aware that his looks is a bad news. He only crash to the library cose that place is out from those people's radar. But after a while, he visit just to watch Ashiya's working.
