Mimic

Mimic (ミミック Mimikku) is a recurring enemy in 62studio's games who hides within a chest and attacks when the player attempts to open her chest. A similar enemy is the Shell Mimic, who hides within a giant sea shell.

Description
Mimics have short blonde hair, pale skin, yellow eyes and the wings and tail common to most succubi. Unlike most succubi, they do not wear anything due to considering their chests as their clothes. As a corollary of this, they do not strip after losing enough Vigor unlike most succubi. Mimics spend their time within liquid-filled wooden chests with gold frames and keyholes.

Lust Grimm
Mimics can be found in various places throughout the world and are initially indistinguishable from normal chests. Most of these are one-time encounters, as after a Mimic is defeated, an empty chest takes her place on the map. However, they occur as respawning enemies in a specific area of the Lost Woods and on levels 4F and 5F of Sonne Labyrinth.

Lust Friend
Mimics again can be found as chests in various places, and most are one-time encounters. Like most enemies, the player can befriend one of them. In versions 1.05 and later, there is a Mimic found in the basement of Desire Church who does respawn after being defeated, which ensures that the player can befriend a Mimic even if they have already defeated all of the others in the world. Additionally, there is a Quiz Mimic in Desire Desert who likes giving quizzes. If the player talks to her and has already befriended Mimic, they can take her quiz.

Trivia

 * The Mimic is a type of monster originally appearing in Dungeons and Dragons, with the ability to disguise itself as an inanimate object (usually a chest). It has since appeared in many other works of fiction.
