You play as Luna, a rookie security officer with psychic powers, fighting her way through a deck-building card battler where the fights, the mystery, and the H-content are all tangled together. It’s an ambitious package — a superpower conspiracy plot, multiple endings, Live2D scenes, and six voiced heroines — aimed squarely at players who want an actual game attached to their eroge, and who don’t mind their yuri served with some considerably rougher kinks on the side.
What works
The setup is more thought-through than the average doujin battle-fuck game. Luna is a police academy student who dreams of “making society better,” admires her older sister, and has been haunted since childhood by psychic hallucinations that hint at something buried in her past. Her power, Replication, is the engine of the plot — as she learns skills from allies and enemies, the world’s hidden truth comes into focus piece by piece. Around her, the writing sketches a real cast: a hardworking classmate with an unglamorous medical-type power and a complex about it, who plays the sharp-tongued straight man to Luna’s airheaded moments; a phantom-like woman tied to the terrorist organization called the Liberators, who has reportedly used multiple different powers and whose true ability nobody has pinned down; and a background case — the “abnormal lust” incidents, where victims lose their reason and can’t be cured — that suggests a mind-controlling esper is loose somewhere. That last thread is doing double duty as both mystery hook and erotic premise, which is exactly the kind of integration this genre usually doesn’t bother with.
Mechanically, the pitch is a card battler with real decisions: you build your deck to match the battle situation, fields change randomly, and the game states outright that your choices steer the story toward different endings. Combined with the Replication conceit — learning skills from friend and foe alike — there’s a coherent loop here where fighting, investigating, and story progress feed each other. The bond system matters too: getting closer to the girls you’re investigating alongside is explicitly framed as the key to the story, which is where the yuri content lives.
The production checklist is genuinely strong for a doujin release: over 200 CGs counting variants, Live2D-animated H-scenes rather than static stills, six voiced female characters, and multiple endings. Language support is unusually broad — Japanese, English, Korean, Russian, and both Simplified and Traditional Chinese — which tells you the circle is serious about reaching players outside Japan.
What doesn’t
The store page spends far more words teasing its mystery than explaining its card game. We know decks exist, battlefields shift randomly, and choices matter — but nothing about deck size, card variety, difficulty, or run length. Deck-builders live or die on that stuff, and a description this vague means you’re buying the combat system on faith. The same goes for the six-language localization: translating a mystery-driven, choice-heavy RPG into five foreign languages is a big job for a doujin circle, and the page gives no indication of who handled it or how polished the English is.
The other honest warning is tonal. The bond-building and yuri framing read soft and romantic, but the tag list tells a spikier story: dubious consent, machine sex, ahegao, and battle-fuck scenarios sit right alongside the girls’ love content. That mix makes sense given the plot — a villain who weaponizes lust is baked into the premise — but if you came for pure, sweet yuri, you should know the game is planning to put its heroines through considerably more than hand-holding.
Who should buy this
This is for players who want gameplay-first eroge: if the idea of a psychic card battler with a conspiracy plot sounds better to you than a pure scene-viewer, LUNA is aiming directly at you, especially if yuri-flavored corruption content is your thing. English is officially supported, along with Korean, Russian, and Chinese, so non-Japanese readers can play this without any workarounds — a rarity worth taking advantage of in this space. Skip it if you want vanilla romance only, or if dub-con and machine content are dealbreakers.
Verdict
7 / 10. On paper this is one of the more ambitious doujin battle-fuck RPGs around — a real deck-builder, a mystery plot that actually integrates its erotic content, strong production values, and full English support — held back only by how much the vague store page asks you to take on trust.
