Sunyu of the Shadowless

Ga-Jang No is a strong, dedicated, and humble man, with much respect for the martial arts. After the death of his lovely wife, this muscle-for-hire just wants an easy job that allows him to be a good father to his three little babies. He’s even happy to pull guard duty and fend off amateur fighters if it means he can return home safely each night. But when a creepy cult starts stealing children from the city, Ga-Jang must step up to the challenge and discover his true warrior potential. (Source: Tapas, edited)

A mysterious man suddenly appears in the desert separating the East and West Continents. A young boy, Yulian Provoke from the Pareia tribe finds this man, and brings him to his village. Turns out the man is an incredibly strong and amazing individual, and he begins to teach the young boy fighting skills.

Is he crazy? Or just the typical attention seeker? Lee Gang-Jin, who doesn't understand the differences between people, and his Master Kwak-No who's the one helping him to understand the differences between people. A warm human story of a student and his Master. (Source: KakaoPage, translated)
