Bouken Danshaku Don: The Lost Sunheart ("Adventures of Don Baron: The Lost Sunheart", roughly) is a horizontal shoot 'em up exclusive to the PC Engine.
The game's plot concerns the titular Sunheart device, which is broken into several pieces and spirited away by a group of malicious eyeball enemies.
The hero, in a series of vehicles, takes down each of the boss creatures that are protecting a piece of the stolen Sunheart.
The game is distinct among shoot 'em ups for allowing players to keep their power-ups after dying.
This does not mitigate the game's difficulty, as it has some very strict checkpointing and many enemies with difficult-to-avoid homing shots.
The game's surreal sense of humor comes through with its bizarre bosses, in some way invoking the flamboyant Cho Aniki series.
About PC Engine
Known as the TurboGrafx-16 outside Japan, the PC Engine (1987) punched well above its small form factor and was hugely successful in Japan despite a limited Western release. Because the Western TurboGrafx-16 library is comparatively small and undersold relative to the platform's technical merits, complete-in-box North American copies are notably scarcer — and pricier — than their Japanese PC Engine counterparts.

Rarity & condition
Only a handful of market sales have been tracked for Bouken Danshaku Don: The Lost Sunheart, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common PC Engine 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.
