DescriptionThese succeeded Sailor 0. The new model was finally completed after numerous version updates, but it seems they just couldn't correct the tripping flaw.

As stated in the description, the improved version of the Sailor 0. Ironically, they also added to it a flaw, which is apparent from her skill set: she has a three-strike attack called Drei Blade and can restore her HP with Refrag, but she also has one called Trip&Fall that causes her to waste her turn due to tripping and landing face-first on the floor. Therefore, and despite her much higher stats, the Sister ∞ is an enemy that shouldn't give problems to anyone, as she only has one real offensive skill.
