Dongfang Chuqi: 13 years old, 165cm. The direct grandson of the Dongfang family. He is carefree, cynical, charming and uneducated by nature (known to the world). Unknown experiences: learned various martial arts and survival methods in the wild since he was a child. He met the lonely Hunli (8 years old) at the age of 6. At the age of 7, he met Echizen Ryuya (9 years old, a character in The Prince of Tennis). From then on, the three of them learned and lived together. When they were 8 years old, three people were accidentally kidnapped by human traffickers (intentionally). In the end, the three of them broke up the Sino-Vietnamese human trafficking gang. Among the captured children, 9 orphans voluntarily followed them, and they were immediately adopted (adopted in the name of their subordinates, but he was not qualified). At the same time, the 9 children learned various knowledge and martial arts with him, and named them respectively: Yang Che, Mu Feng, Yu Ji, Ling Chen, Luo Han, Su Mei, Yan Xiao, Chi Xiao, and Jue Xiao. At the age of ten, I crossed Death Ridge alone at the junction of Sichuan and Yunnan. When I came out, I was covered in blood and dirty, with countless wounds on my body, but none of them hurt my vitals. It took me a week, and I was the first person to come out of Death Ridge alive. The [Final Organization] was established in 2001 and has four departments managed by Su Mei, Yan Xi, Chi Xi, and Jue Xi, with Hun Li as the general responsible; the [Initial Group] has five departments, with Yang Che, Mu Feng, Yu Ji, Ling Chen, Luo Han, and Echizen Ryuya as the honorary responsibility. At the age of eleven, Ryuya Echizen left, Chu Qi and Hun Li returned to their hometown in the East. At the age of thirteen, they met Yukimura Seiichi and others, and the story began to unfold.
Yukimura Seiichi: He lived in the Yukimura family until he was 4 years old. After he was 4 years old, he moved away from the family with his grandmother and father. He can freely control his own actions before he is 20 years old. After he is 20 years old, he must return to the Yukimura Group. He has a slender and handsome appearance, a gentle and generous personality, seems easy-going but does not get along easily, and does not hide his truest thoughts about the people he values and is a bit sinister.
He loves tennis very much and is serious about his work, especially in matters he likes. Because of the agreement with his grandmother, Yukimura has a strong desire to win in his favorite tennis.
Since he was a child, he has been frequently attacked and plotted against by his family members.
Although he appears to be the head of the Rikkai Tennis Club, he is actually a 3rd degree black belt in karate and the successor of Tenka Shoden and Shinto Ryu. Few people understand Yukimura's true strength, and many people are easily fooled by Yukimura's slender appearance.
Privately, he founded an entertainment company headed by Yukimura, which has countless popular stars and has a great influence on the Japanese entertainment industry!
