Carroll/Succubus in Wonderland

Carroll (キャロル Kyaroru) is a major villain and later ally in Succubus in Wonderland.

Profile
''One of the two daughters of the Queen of Hearts. She is callous and doesn't care about what methods she uses, but is also an extreme mothercon. And while she appears strong, she's also weak in some places (according to Lewis).''

Strategy
The first battle is fought with Reto alone. Carroll is far too powerful to be defeated at this point normally. She will do nothing on her first turn, then use a powerful attack on the second turn that will inevitably bring Reto's Vigor to 0. As usual, Reto will recover to 50% Vigor. Afterwards, Carroll will use much weaker attacks, and will occasionally skip her turn again, making her possible to defeat. Use Pussy attacks to defeat her. One thing to watch out for is that she occasionally gives herself a buff that increases her Skill and Endurance: while this buff is active, you may wish to focus on defending rather than attacking.

In the second battle you can have an ally, and it's ideal to have someone of the Clubs suit in order to counter Carroll. Ironically, Lewis (despite being treated as your ally in the cutscenes) is a poor option for this battle, since she's of the Hearts suit and thus weak to Carroll.

Recruitment
Carroll is recruited in Proof Undersea Tunnel. Shortly after Lewis is kidnapped by slimes, Carroll will join the party.

As a companion
Carroll has the rank Queen of Spades (♠ Q). When recruited, she is level 30, has 2113 Vigor and 676 Stamina, and knows all Lv1 and most Lv2 skills, as well as Kiss Lv3, Wait, Scissoring, Endure and Observe. Shortly after being recruited, she will explain how she learned a skill to fight slimes, after which she will learn the Energy Shot skill. She also learns a special skill (shared with Lewis), Royal Aura, after her and Lewis' combined H-scene with Reto (see below for details on how to get this).

H-Scenes
Carroll has a titjob H-scene if the player loses to her in her second battle. The artwork for this scene is reused for her level drain scene. Losing to Carroll in her second battle does not result in a H-scene with her, but in a H-scene where Lewis is attacked by three succubi.

If the player loses to the Slime Queen in her first battle, Carroll will be raped by the Slime Queen.

After recruiting Carroll and saving Lewis, the bed in Mel Village's vacant house can be examined for a scene with both of the sisters.

Carroll is also one of the succubi who has additional "Beloved" scenes in the Inn of Love in Venom Underground City. One of these scenes is a variation on her level drain scene (and rewards you with the Carroll Brooch equipment), while the other is a new scene. To access these scenes, you must unlock Carroll's "Beloved" passive ability in the SP menu. You then need to have Carroll as your ally, go to the inn, and either use the crystal or sleep in the bed.
