She is the weakest of the Apoptosis in Tartarus so that she will appear in a group of three a lot of the time. Systematic Cleaning (F) and Systematic Cleaning (M) are her strongest attacks. It can inflict Slime, Trance, and Blind, all in one attack, while still dealing a good amount of damage. Trance will prevent the target from taking any action for up to three turns, and can't be cured early. Typically, you would replace this member with one from the backline, but if it binds the target as well, then you can't do that, and you can't struggle either. Combined with Slimed, which increases pleasure damage, you can see why it is such a deadly attack.
She is weak to the lightning and earth elements, so Gob, Ilias, Vanilla, and Rami help here. Since she's weak to shock, try using an attack which has a chance to cause it. She resists everything else, so try to avoid using attacks which don't use the lightning and earth attributes.
As a note, you want to recruit her and the rest of the Apoptosis as soon as possible. They have great elemental resistances and status resistances which are invaluable in the late game. But Sully in particular, as she has access to the Sea-Dweller race, and she can then become a member of the Sea-Dragon dancer race. They have access to a unique skill called Timewarp dance. It has a chance to stop all enemies in the group or at least slow them. Invaluable in the late game.
Her japanese name is シュリー(Shurī). Also, in japanese game data, her english name is Shri, which possibly came from her shrimp-like appearance. The name 'Sully' seems to be a mistranslation, since in Japanese, they write the name 'Sully' as 'サリー(Sarī)'.
