Hearts Soldier/Succubus in Wonderland

Hearts Soldier (ハートアーミー Hāto āmī) is an enemy and potential companion in Succubus in Wonderland.

Profile
''A card soldier who was put on trial for stealing tarts. Due to excessive dieting, the jury lost their reason and fled. She loves sweets, and also loves energetic people, both humans and succubi.''

Strategy
Like the other card soldiers, Hearts Soldier has a breastfeeding handjob attack that drains Reto' level. Moreover, she becomes stronger based on the number of levels she has drained this way, and this effect accumulates even after multiple battles. To reset the level drain counter, you must use Hatter's crystal ball to erase your memories of defeat.

Hearts Soldier is vulnerable to Mouth attacks and, due to being of the Hearts suit, is countered by succubi of the Spades suit. Avoid using Nipple Suck or Nipple Suck+ on her, as this will cause her to counterattack.

Recruitment
Hearts Soldier's touch challenge is in Amidst Hearts, one of the four areas accessed from area 7F of Wonder Castle. To attempt this challenge, you need to either lose 30 levels to the level drain of a Hearts Soldier enemy, or possess the Hearts Lance key item. The latter can be found in a silver chest in 3F, which in turn requires the Hearts Key (one of Hearts Soldier's drops) to open. This challenge is Norma 4 and has a difficulty of 5 stars. Hearts Soldier's weak points are her right armpit, right breast, the belt on her left thigh, and knees. You get 1000 experience for recruiting her.

As a companion
Hearts Soldier has the rank Jack of Hearts. When recruited, she is level 15, has 1066 Vigor and 272 Stamina, and knows all level 1 skills, some level 2 skills, Wait, Scissoring and Resist. After the player experiences the card soldiers' H-scene, Hearts Soldier learns the skill Army Heal.

Additional Scenes
Hearts Soldier and the other card soldiers have a special scene that becomes available after all four of them have been recruited. To experience this scene, go to the area of Wonder Castle 3F with the four silver chests and examine the glowing circle in the middle.

Trivia

 * Hearts Soldier is based on both the playing card soldiers and the Knave of Hearts from Alice's Adventures in Wonderland, the latter of whom was also put on trial for stealing tarts. Note that "knave" is an alternate name for the jack in playing cards, referencing Hearts Soldier's rank.
