System & Gameplay Notes

This is a traditional RPG where you’ll need to level up, manage money, and purchase new gear. Enemies are designed to be dangerous, since defeating them is a key goal. The number of battles has been reduced.

Version 3.00: escaping from combat has been simplified. For convenience, healing items are also available in your inventory on the map. Drawing lessons from the previous title, the game removes time-consuming synthesis-style systems, keeping the overall structure relatively straightforward.

• Enemies appear as symbols on the map.
• The enemy design is friendly-looking, so combat typically starts only when you touch an enemy.



• However, accidental contact can be risky—the chance of failure is high.
• Your character’s avatar can change depending on status effects.

Adult Content Summary (In-Game)

During battles, the target can continue performing sexual harassment attacks. As the pleasure from these attacks increases, the corresponding damage also rises, making it easier for HP to drop. When HP reaches 0, outcomes such as penetration and ejaculation become possible, and at that time HP and NP are restored. The game is described as ending when the uterus is filled with semen.

About the H Scenes

The game emphasizes the experience of losing combat, so it does not rely on long, standalone H scenes. It also notes that abnormal scene types such as anal sex, bloating, or childbirth are not included.

Fantastic Benefits / Main Setting

Modern Mythbusters

Play as Natsuno while living a double life: college life by day, and hunting lurking yokai (demons) in Tokyo’s nightlife at night. Use academic research to identify enemy weaknesses while staying hidden.

Time Warp Zones

Jump through shifting locations where neon streets blend into feudal-era battlefields. Each area hides clues about “him” and the return of demonic forces.

Tech Meets Magic

Turn your smartphone into a spirit detector, craft amulets using an app, and summon shikigami (guardian spirits) to fight enemies using augmented reality.

Story Summary

The background is framed by a warning from a fragment of a lost ancient document: “When people forget ‘him’, we may see millions of demons reveling in modern times…” Can Sakura Natsuno protect world peace?
