Just wondering why you didn’ follow to original? After Zheng passed the test he was given the next stage of constraint free, so mc would be stage three now.
MC seems strong but I think his team is too weak if you compare with the original TI Team China/Devil etc. TI had really strong & smart side characters.
The mc should get a ghoul bloodline from Tokyo ghoul an aim for his kagune to be a arm sword type so that he can use the force weapon technique on it while also benefiting from any body buffs
