Fa Jin (發勁 (ファ・ジン), Fa Jin lit. Hand Power), also known as Internal Energy Release (脂肪強, Hakkei) or Magical Particle Destruction Fist (魔粒・破拳, Mashi Haken) is an ancient Joyan martial art technique that is a mixture of hand-to-hand combat and magical energies. It was initially exclusive to the Joyan Monks, an ancient cabal of peace-seeking warriors whom would only use their special abilities in self-defense.


In order to utilize Fa Jin, the user charges their magical energy into one of their hands, condensing it unto its utmost limit until their hand starts overflowing in pure energy, radiating eternano so brightly that it seems to blind those whom turn their gaze upon the user. Upon unleashing the fist, the user strikes forward with all of their might, unleashing the concentrated eternano upon their fist towards the foe, essentially transferring the user's own magical energy into the opponent's body, causing a powerful surge that grievously wounds them from within; the attack is actually derived from Chinese martial arts. The movement of the attack is essentially invisible, and it truly seems like the user shoots their opponent, except that the resulting impact is not akin to an actual pistol, but to a small hand-held cannon and powerful enough to propel the unlucky recipient several meters away. The incredible speed both makes the strike far more powerful, and harder to dodge; connecting instantly with the target; the attack seems to strike the target multiple times simultaneously, creating a number of surreal, delayed shockwaves, and it is capable of slashing the user's opponents and sending them flying away from the user, with enough force to make them fall off cliffs and high places they might be standing on. However, this attack can be stopped if the eternano cannot flow through the user's arm or hand, essentially resulting in a blunt strike that, while powerful, does only one third of the damage that it normally would. The attack can be performed using the user's arms, or even their legs with enough training.


  • Fa jin, fajin, or fa chin (fā jìn, 發勁) is a term used in some Chinese martial arts, particularly the internal martial arts, such as Xingyiquan, T'ai chi ch'uan (Taijiquan), Baguazhang, Bak Mei and Bājíquán. It means to issue or discharge power explosively or refining the explosive power, and is not specific to any particular striking method. Jìn (勁), or "power", is often confused by Westerners with the related concept of jīng (精), which literally means "essence."
