This boss has 3 stages and the hardest is stage 1, after that the other 2 just basically dodge and dodge.
This guide is only in stage 1 only
He will change his form 2 times, at 70% HP and 50% HP (3:06).
Try to blow his shield (the white above his HP bar) as quick as possible, the Fan (You will get them after final boss chapter 5) is extremely useful.
Notice: Do not use your transformation, he will transform as well, and his transform is much stronger than yours. It isn't fair trade if you started it.
At 50% HP (3:06), try to dodge the lasers from the bottom Erlang, the top one never hit you.
At 3:25 and 3:41, hold your V will counter all the blades to you.
A lot of people use Immobilize, but I use Ring of Fire since I can freely all in with the boss without worrying about dying quickly.
At 17:15, it is only a cinematic scene, you won't die so don't worry.
