Good chapter but yea feel the guys needed a bigger beat down.
My guess is Jae being taught by all of the girls and coming up with a mixed MA style of his own.
Not particularly advanced stuff but basics that he can apply to a wide range of situations.
Unless we do get some generic shounen stuff like a ability to take in info like a super computer or hidden talent of some sort that lets him become hax bad ass.
Either way heres hoping we get more of the league guardian now
