The "Kei kei kei loan" arc (often associated with specific doujin circles known for high-quality art and dark storytelling) distinguishes itself by treating the brainwashing not as a simple plot device for adult content, but as a slow-burning tragedy. The "Final" tag indicates the ultimate payoff: the irreversible destruction of the old Reimu and the birth of a new, subservient entity.

The story of Reimu Gets Brainwashed -Final- -Kei kei kei loan- is a masterpiece of fan-driven dark fiction, blending Touhou’s established lore with real-world anxieties about debt and identity. It reminds us that in Gensokyo—as in life—the most terrifying monsters aren’t always youkai. Sometimes, they’re loan officers with a gentle smile, a binding contract, and a laugh that sounds like the death of the self.
