Unlike typical high-school flings and love-dating simulations, the atmosphere throughout the game is gloomy and cold as the reality that had hit the main character.
One day he meets an apprentice angel who starts helping him in his encounters with girls he meets in the school and dormitory he is staying at.
Each girl he meets seems to bring him one step closer to his lost memories.
Choices which are occasionally available will lead player towards one of several different endings.
About Nintendo DS
The dual-screen, touch-enabled Nintendo DS (2004) became the best-selling handheld of all time, helped by its huge and genre-diverse library. Cartridge-based DS games have held up well physically over 20 years, and complete-in-box copies of the system's biggest sellers (Nintendogs, Pokémon, Mario Kart) remain very accessible for new collectors starting out.
Gamevaro tracks Monochrome Boo & Baby Boo: Kururin Boo for Nintendo DS with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Monochrome Boo & Baby Boo: Kururin Boo to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This NDS release dates back to 2009.

Rarity & condition
Only a handful of market sales have been tracked for Monochrome Boo & Baby Boo: Kururin Boo, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Nintendo DS titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
