A reclusive descendant of the Shuangyue clan, carrying the ancestral black sword "Xian Shuang", lives in seclusion in Shuangyue Village in the East China Sea. He has a lazy temperament, sleepiness and idleness. His only obsession is to protect his sister Guina and her companions.
In the last year of Roger's life, mysterious forces raided the village. To protect his beloved, he was forced to leave the East China Sea and embark on the treacherous and treacherous great sea route. On the way, he encountered the Baroque Cooperative and Sky Island forces. He always regarded himself as a "guardian" and did not steal the lead of the protagonist group, but never flinched when his companions were in danger.
As his domineering power gradually awakens and Ryoma's bloodline gradually unlocks, he is too lazy to compete for fame and fortune, but relies on his strength to leave the legend of "Xianjian" on the great route, guarding the stability of one side and facing his fate.
