Gamin Yoon

Gamin Yoon ("윤가민") is the main protagonist of the manhwa, Study Group. A high school student with a dream of entering a 4-year university and becoming a college student. He is the founder of Yusong Vocational Engineering High Study Group. His motto is "To hell with circumstances, I create opportunities".

Background
Everyone that knows Gamin can be sure to say that Gamin is a dimwitt when it comes to academics. However, that never really stopped him from chasing his other goals. Being a huge Bruce Lee fan, Gamin secretly trained in Jeet Kune Do with his uncle. He does a morning-calisthenic session for about 2 hours everyday right after he wakes up.

He entered Yusong Vocational Engineering High, and in only 3 months, got himself the title 'Gamin Yoon the Monster ' due to his fighting prowess.

Fighting Prowess
Gamin's martial arts style is called 'Jeet Kune Do', a martial arts invented and made famous by Bruce Lee, which consists of every martial art he ever learnt. In short, this is basically the first form of Modern MMA.

Stamina: Gamin possess astounding stamina, able to fight multiple opponents at once, either separately in a row or a gang assault.

Power: Despite his thin appearance, Gamin's raw strength is something you do not ever wish to underestimate. According to one of the people who bullied Sehyun Lee, his power is even greater than Kang Taeo, the former No. 1 of Yusong High's freshman year fighting ranks. This is also shown in Chapter 34, where he could incorporate his monstrous strength in snaps.

Technique: Not only does he possess exceptional stamina and power, Gamin is also really good when it comes to his martial arts form. His punches always possess fluidity without diminishing their strength, making them 'deadly '. The same can be said about Gamin's kicks, his 'leg muscle and joint endurance' being quite high, able to do five sidekicks (each at a different height) without putting the kicking leg down for even a moment.

Uncle's Forbidden Techniques: The Uncle's Forbidden Technique (or "UFT") is a technique used by Gamin and forbidden by his Uncle, due to the fact that it can easily overpower him whenever they used it during sparring sessions.
