Grand Succubus/Succubus in Wonderland

Grand Succubus (グランドサキュバス Gurando Sakyubasu) is an enemy and potential companion in Succubus in Wonderland. She is one of the succubi debuting in version 2.0 of the game.

Profile
''A succubus who reigns at the apex and wields powerful magics. Her strong magic is always leaking out, so she's always hungry and her appetite is also without equal. She's not easily satisfied, so it seems she attacks both humans and other succubi.''

Strategy
Grand Succubus begins her battle by creating a Pleasure Shield. This can be broken using the Shield Killer skill or any regular attack (but the latter has a low probability of success). She is vulnerable to Chest attacks and, due to being of the Hearts suit, is countered by succubi of the Spades suit.

If the battle lasts to the 15th turn, Grand Succubus will use Minimum Magic, instantly defeating the player (only in versions 2.06 and later).

Recruitment
A Grand Succubus NPC appears in Proof Undersea Tunnel: Room. While this area can be accessed in earlier versions of the game, Grand Succubus will not appear then. You can recruit her by talking to her, and you gain 5000 experience for recruiting her.

As a companion
Grand Succubus has the rank Ace of Hearts. When recruited, she is level 30, has 1767 Vigor and 676 Stamina, knows most Lv1 and Lv2 skills with some Lv3 skills and with Scissoring, Energy Wave and Resist.

H-scenes
Grand Succubus has the standard set of H-scenes: one for losing to her the first time, one for subsequent losses, and one for her level drain. These have her shrink Reto and force him into her vagina.
