Cell Domain

Unlocked. The heavy prison door swings open in the dead silence.
The facility has already fallen, now transformed into a labyrinth swirling with lust and malice.
A mad world where the boundaries of the flesh are violated and rewritten.
The pitiful souls left behind—will they escape from the horrors lurking in the darkness, or will their bodies be taken? All they can do is resist.

H System
■High-detail H animations
Enemies capture the player and attack to devour their flesh.
If resistance after restraint (wiggling the stick / button mashing) fails, the H animation begins.
All enemies have unique animations, from foreplay to insertion and climax, with staged continuous scenes.
■Seeding, pregnancy, and childbirth
Some enemies implant seeds in your womb (seeding) and forcibly impregnate you.
As pregnancy progresses, once the delivery month arrives, the player collapses on the spot and gives birth to fertilized creatures.
After childbirth, the body becomes a breast-milk constitution (lactation), and due to this physiological phenomenon, the breasts forcibly enlarge (gigantomastia).
As a seedbed for the aliens, the player must endure violation while carrying a swollen belly or chest.
※All of these body changes are fully supported by H animations.
■Status ailments
Many enemies and environmental traps trigger various status ailments that affect gameplay.
・Abdominal semen accumulation (internal cum belly)—The belly bulges from internal ejaculation, slowing movement until it subsides over time.
・Breast-milk constitution—The breasts swell and greatly enlarge due to milk secretion.
・Aphrodisiac—Consciousness becomes hazy, making it hard to escape enemy restraints.
・Slime—The whole body is covered in sticky fluid, reducing movement speed.
・Mero—Sensitivity rises due to drug effects, and all stimulation easily turns into pleasure.
・Spider silk—Sticky threads wrap around the body, restricting movement and making it hard to walk.
...and more!
■Clothing damage
Once caught by an enemy, the worn clothing takes damage.
Each part has up to 3 stages of damage (variations), each with dedicated artwork.
Tears and rips are dynamically reflected and persist across all animations.
As clothing is destroyed and skin exposure increases, it becomes harder to shake off enemies and escape.
