After reincarnation in the Hunter world, he became the only son of an ordinary family. He was weak but calm since childhood. Without a cheat code or an external system, he relied on his memories of his previous life and his understanding of the ability of mind to hone his skills in the Sky Arena and slowly mastered the ability of the materialization system of mind.

He is good at using his mind to materialize dual guns and tactical daggers, and combined with the tactical knowledge of his previous life, he has developed a combination of close combat and long-range combat methods. When he was a teenager, he met Killua in the tower, and later met Gon and others during the Hunter Exam, but he always acted independently, keeping restraint and distance.

Later, he participated in the brigade battle, planned an assassination in York New Town, and successfully sniped Franklin; in the Chimera Ant chapter, he entered the battlefield alone, fought against the Ant King, and ended the war with his calmness and firepower.

He does not seek fame, nor does he want to be the protagonist. He just wants to survive and become stronger in this dangerous world, and to keep some bottom line as much as possible. In the end, he left everyone and embarked on a journey to the dark continent alone.
