|Twin dragon surprise attackers|
The Sisters (シスターズ Shisutāzu) are an optional boss battle fought in the Egg Corridor?. They consist of two identical dragons who deploy the same attacks.
The Sisters can be encountered in the Egg Observation Room? after obtaining the maximum missiles upgrade in the chest. If Quote does not exit the room within a short window of time, all exits shut, and the battle with the Sisters commences.
It is possible for the player to leave the Egg Observation Room? and receive the missile ammunition upgrade before the Sisters appear. This will cause the Sisters to no longer appear when the room is reentered. The player is also able to skip the upgrade entirely and never fight the Sisters.
The Sisters circle clockwise around Quote at an alike rate. Intermittently, one or both will open their mouth. After about five seconds has passed, they emit a chain of fireballs that close in on the platform in the middle of the room. Once they have cycled around Quote several times, they pause and switch to moving counterclockwise, but continue to open their mouths.
When the Sisters have sustained a certain amount of damage, they will keep their mouths open the entire time and release a constant stream of fireballs until defeated.
Either one of these dragons can be hurt when their mouths are open. If shot in this pose, their mouths close so that their tongue sticks out and their eyes turn green. The Sisters can continue to be harmed when they have this expression. They can also be damaged if they send out fireballs, so long as their mouths are still open. Contact with any of the Sisters or their fireballs subtracts 10 HP from Quote's health. Both share the same health bar, so the player can limit themselves to fighting one dragon and still defeat them.
When the health bar is fully depleted, the Sisters display the same expression as though they were hurt when their mouths were open. An outward white explosion occurs and a victory message displays after. All spikes disappear from the room and both exits are restored. A save disk, which was not in the room before, drops to the floor below the platform where the chest was.
