The Shack (バラック地点 Barakku Chiten) is a location in the Mimiga Village. It is also the place where Quote fights the first (and first optional) boss, Balrog. After Balrog breaks in, the door is permanently damaged.
When Quote first enters the shack, Toroko will mistake him for one of The Doctor's minions and attack him. She can be stopped with a single shot with his Polar Star, though she deals 1 damage per hit, enough to level down the player's weapon and make the fight with Balrog a bit harder.
