CelSector [YumamiSoft]
Unlock. The heavy door of the cell opens in silence.

The facility has fallen, now a maze swirling with desire and malice.

A world where the boundaries of flesh are violated and rewritten in madness.

The pitiful souls left within must either escape the monstrous entities lurking in the darkness or have their bodies taken by them—they must resist.

H System

High-Resolution H Animations
Enemies capture the player and assault to devour their body. If resistance (lever pulls/repeated button presses) from restraint fails, H animations begin. Every enemy has unique animations with sequential stages from foreplay to penetration to climax.
Impregnation, Pregnancy, and Birth
Some enemies implant seeds (impregnation) and forcibly impregnate the player. Upon reaching full term, the player collapses and gives birth to the fertilized type of creature on the spot. After birth, the player becomes lactational (lactation), causing breasts to forcibly enlarge (gigantification) due to this physiological phenomenon. The player becomes a breeding ground for the monsters and is assaulted with an expanded belly and chest.
※All body shape changes are fully supported in H animations.
Status Ailments (Bad Status)
Many enemies and environmental traps inflict various status ailments that affect gameplay.
- Abdominal Semen Retention (Creampie Belly) - Belly swells from creampie semen, slowing movement until it subsides over time.
- Lactation - Breasts swell and enlarge due to milk secretion.
- Aphrodisiac - Consciousness becomes foggy, making it harder to escape enemy restraints.
- Slimy (Slime) - Body covered in sticky fluid, reducing movement speed.
- Aphrodisiac - Sensitivity increases due to drug effects, making all stimulation more likely to turn into pleasure.
- Spider Thread - Sticky threads bind the body, restricting movement and making walking difficult.
- …And many more!
Costume Destruction (Armor Break)
When caught by enemies, worn clothing takes damage. Each body part has up to 3 stages of damage states (differences), with dedicated art for each. Tears and rips are dynamically reflected and maintained throughout all animations. The more clothing is destroyed and skin exposed, the harder it becomes to shake off enemies and escape.

Shape Variations
Many clothing items have shape variations, allowing for meticulously curated outfits. For example, socks can be changed to ankle length, thigh-highs, or over-the-knee. For tank tops, you can select standard length, cropped, or extreme styles revealing the “lower hemisphere (underbust).”
Outfit Saving
To enjoy dress-up even more, up to 3 coordinate presets can be saved. These can be instantly switched even within the gallery (recap) or during gameplay.
