I thought the master was evill turn out hes not or is he?

Mind you, rainbow city masters are ableist af, literal dictators that kill anyone who oppose them and care about beating each other to gain more power rather than working towards the safety of the people. Also do you know why the helicopter was shot down? Because second master ordered soldiers to kill everyone (even innocent people) who try to go to JeJu island for safety. Second master is also manipulative af and spews a shit ton of bs that Major Kwak can see right through. He’s all like “oh I’m nothing like first master, he’s evil” when everything he does is to suit his own agenda

I agree. That's why Mayor Kwak doesn't choose side. He know very well first master and second master are EVIL AS HELL
