Animation appeared in the second season ①( 17 photos) Personality: handsome and cool, strong and idolized, grateful and fond of playing tricks on people. The black belly belongs to RK, and Ruiqi's brother Ruikai (formerly known as Ruikai) left home when he became the head of the Knights Order. Ruikai is a master skier. He was injured by a knight in the full crown skiing competition, resulting in deafness in his left ear. Ruikai started playing tricks on his brother's subordinates and then ran away from home. Ruikai is annoyed with Princess Mo because his brother is protecting his subordinates. Ruikai stole the butterfly glasses that the old woman gave to the hunter M, and occasionally saw the insulted ruby (homophonic: ruby) super ram, which can turn into a protector. Ruikai chose Ruikai's abbreviation R.K. to steal Moore. He used intact escape props, made full use of teleportation, and took off and landed in the air to defeat Chang. Ruikai became suspicious. He wanted to steal the throne of King Moore and make everyone collapse. But when RK saw that his brother had lost his life for himself, he suddenly found that his brother had a kind heart and his parents had already left (not died). Ruikai shed tears of regret. He goes to the castle monument every day, hoping to see his brother. ...

RK was originally blue, but later it was dyed pink. In order to completely discourage his brother from becoming a knight, he tried his best. Ruikai and Ruiqi live in a small house not far from the knights. Their parents had contact with King Moore, and they had contact with their parents in martial arts, skiing and various talents since childhood. RK's father is an excellent explorer with excellent judgment, and RK's mother is a kind Dr. Ram. Ruikai and Ricky, whom crow's father called God of Love, were loved by many Moors since childhood, and their parents also loved Ricky very much, which made Ruikai suspicious and introverted. On the contrary, Ricky loves his younger brother very much, because Ruikai is handsome and outstanding in special aspects, and is especially loved by ski teachers. On the 14th day after the Black Forest was closed, Ruiqi Ruikai's parents received the above request to explore the Black Forest. Ruiqi Ruikai was only 4 years old at that time. Mom and Dad gave them to the beautiful and lovely nanny Matt Ai, who was sickly. When Ruiqi 12 years old, Matai ran away, and Ruiqi came to take care of her younger brother than Princess Mo. Sure enough, his parents left Ruiqiruikai 10 and never came back. I heard that they were lost under the guidance of King Moore.
