Nuki Doki- -tenshi To Akuma No Sakusei Battle- 【Full Version】

You are Lux, a newly assigned Creator in the Celestial Realm. But the Council of Eternity is lazy—so they’ve outsourced the creation of souls to a video game battle tournament.

The Game: For every human born, an Angel (Cupio) and a Demon (Libid-o) compete in a “Sakusei Battle.” They race to fill a blank canvas (a Soul Egg) with their own traits. Angels add Virtue (selflessness, duty, order). Demons add Instinct (desire, curiosity, chaos).

The Problem: Your assigned Angel, Seraphi, is clumsy and pure. Your assigned Demon, Dagon, is seductive and lazy. If either wins too much, the human soul becomes unbalanced (a Saint or a Criminal). The Secret: The more unbalanced the soul, the stronger the bond between you and your partner.

The protagonist finds himself caught in a ridiculous bet between a clumsy but earnest angel and a mischievous demon girl.
The challenge? A “sakusei battle” – whoever extracts the most… essence from him using various playful, erotic methods wins the right to claim his soul (or a similarly high-stakes prize).
The angel wants to save him, the demon wants to corrupt him, but both end up competing for his... attention.

Expect over-the-top comedic situations, rivalry between the heroines, and little plot beyond setting up the next round of minigames.

Nuki Doki -Tenshi to Akuma no Sakusei Battle- is a Japanese erotic visual novel / dating-sim originally developed for PC with anime-style character art. It mixes relationship-building and branching story routes with adult scenes, plus light strategy/minigame elements tied to “battle” or competition framing between angelic (tenshi) and demonic (akuma) factions. The title’s tone is comedic and romantic with ecchi content and multiple endings determined by player choices. Nuki Doki- -Tenshi to Akuma no Sakusei Battle-

[Setting: Post-battle. The Soul Egg turns purple (Balanced). A neutral human is born.]

Seraphi: “Hmph. A balanced soul. Boring. I wanted him to donate to charity.”

Dagon: “And I wanted her to steal a yacht. We both lose. How romantic.”

Lux: “Why are you two looking at me like that?”

Seraphi: “Because, Lux… when a soul is perfectly balanced, the Creator gets the leftover energy.” (She blushes) You are Lux , a newly assigned Creator

Dagon: (Leans close) “And leftover energy makes you glow. Do you know what glowing attracts, little Lux?”

System Popup: > ATTENTION: Avoid skin contact with either party for the next 10 seconds.

Days turned into weeks of relentless assault. Yamato was exhausted. He was a pawn in a game where the board was his own sanity.

One evening, after a particularly intense "battle" in the gym storage room, Yamato sat on the school roof, panting. Sera sat next to him, nursing a bruise from Lilith’s latest trap. For a moment, the Angel dropped her formal façade. Nuki Doki -Tenshi to Akuma no Sakusei Battle-

"Why me?" Yamato asked, staring at the sunset.

"Because you are the fulcrum," Sera admitted quietly. "Your soul is balanced perfectly between light and dark. I... I was told this would be easy. But you are stubborn."

Lilith appeared behind them, leaning against the fence. She didn't attack. Instead, she sighed. "It's annoying, isn't it? I have seduced kings and toppled empires. Yet you, a schoolboy, resist."

For a brief moment, the three of them weren't enemies. They were just three beings caught in a cosmic bureaucracy. Yamato looked at Sera, who was trying to hide her blushing face, and at Lilith, whose cold eyes softened just a fraction.

He realized he didn't want to win the game for either side. He wanted to break the game.
