Sachi Faker

Sachi (사치), also known as the "Ticket Hunter", is a D-class Regular and part of the 3 top predators within the Hell Train test. He is apparently the one that Regulars should most be afraid of at the first station.

Sachi is said to possess outstanding physical ability and "special" Shinsoo controlling abilities. Also it is said that he is "absolutely" powerful at "one-vs-many" battles.
