Samdak

A mysterious figure concealed behind a chicken-head mask, running a channel with zero views to teach street-fighting techniques. Beneath that disguise lies a top-tier soldier who once served in a classified special forces unit and held a license to kill. Through masterful martial arts and a series of instructional videos, he guided protagonist Shimura Kota's rise from the bottom, standing as the most pivotal mentor and spiritual backbone on his path to growth—while remaining the world's most formidable hidden powerhouse.
