About Touhou: Scarlet Curiosity
Touhou: Scarlet Curiosity is a fan‑made action RPG that follows vampire Remilia Scarlet and her maid Sakuya Izayoi after a monster sighting threatens their mansion. Their investigation propels them into chaotic battles beyond the walls of their estate, driven by curiosity and a desire for revenge.
The game mixes fast‑paced combat with RPG progression, offering two distinct characters, five customizable action buttons, equipment with variable stats, a Bullet Hell difficulty option, 4K visual support, and a soundtrack of 35 arranged Touhou tracks.
01 / THE GUIDE
Playable Characters
Players may select either Remilia Scarlet or Sakuya Izayoi at the start. The description notes that Remilia’s attacks hit hard while Sakuya’s are more technical, giving each a different combat feel.
Both characters share the same underlying systems—leveling, equipment, and button assignment—so the core progression remains consistent regardless of which side of the mansion you choose.
- Try both characters early to see which attack rhythm matches your style.
- Watch how each character’s attack speed influences combo building.

Combat Mechanics
The game uses five action buttons that can be bound to any learned skill, allowing players to arrange their preferred abilities for quick access during fights.
Combos increase attack power and experience per kill when enemies are hit in rapid succession; the boost fades over time or when the player takes damage, encouraging continuous aggressive play.
- Assign frequently used skills to the most comfortable buttons.
- Avoid taking damage to keep combo bonuses active longer.

03 / THE GUIDE
Equipment System
New equipment drops with individual stats, meaning two items sharing a name can still show notable variances in their stats. Collecting varied gear lets players shape their combat strengths.
The description hints that rare pieces may grant entirely new skills, so hunting for uncommon items can expand a character’s ability set beyond the basic repertoire.
- Compare the numeric stats of similarly named items before equipping.
- Prioritize rare gear if you want access to new skill options.

Audio & Visual Presentation
A total of 35 background music tracks, arranged from previous Touhou titles by Hachimitsu‑Lemon, play throughout the game, providing a familiar yet fresh auditory backdrop.
Visuals support 4K resolution, allowing the fast‑moving action and projectile patterns to be displayed with high detail for players with capable hardware.
- Enable 4K mode if your system can handle it for sharper visuals.
- Listen to the BGM while testing combos to feel the rhythm of encounters.
05 / THE GUIDE
Bullet Hell Mode
Starting the game in Bullet Hell mode dramatically raises the quantity and intensity of enemy projectiles, creating a heightened challenge for players seeking extreme difficulty.
The mode is optional and can be used to test skill limits or simply enjoy a more frenetic combat environment after mastering basic mechanics.
- Activate Bullet Hell mode after you are comfortable with standard enemy patterns.
- Use the mode to practice dodging dense projectile streams.
