This mission starts automatically after completing the mission "Mari". It is the final confrontation with the altered form of your main opponent in the game, which is Hannya.
After infiltrating the daidarabotchi, Akito and KK enter what appears to be a recreation of Mari's mind and memories.
Within, Akito is confronted by thoughts he never realized his sister had. The experience gives him the determination to find her and talk things over together.
Your main task in this battle is to extract three cores from three masks. Two of them are located on the sides of the beast and the third on its back. For this to be possible, you must first inflict a sufficient amount of damage to the mask.
One of the attacks used by your opponent are shock waves. You can jump over the waves or use blocks to reduce the damage you receive.
Another type of attack is the "wave of arms." When you are caught by them you will be severely slowed down.
The boss's arsenal also includes such attacks as sweeps with its long arms, spraying green energy, charging or ranged projectile attacks.
The charge will be carried out when you see him extend his two long legs.
After extracting the first two cores, the boss will hide for a while and a few visitors will enter the arena. You must kill them to be able to fight the boss again.
After removing the last of the cores, Hannya will be finally defeated and you will watch the conclusion of the story which in the mission journal appears as a separate mission - "Farewells".
