Shun is a drunken kung-fu user who plays with his opponent by moving as if he were drunk.
There is a "drink count" system in which the higher this count, the higher the attack power and the more techniques he can use.
The number of drinks he has increases when he uses or hits certain techniques, so it is important to master them.
There is also a wide variety of stances to choose from, such as the Tentouritsu handstand stance and the Oushin lying down stance.
Use the variety of tricky stances to play around with your opponent and increase his drinks, then use powerful moves to break down your opponent when your drink count increases.
