Play Ayakashi no Shiro (Japan) Online
Creepy little Game Boy RPG where you recruit the ghosts you fight—nothing like watching a lantern spirit shriek at you while you try to steal its moves. The castle’s full of weirdos, from grumpy samurai ghosts to dramatic possessed umbrellas.

Ayakashi no Shiro is a Japan-only Game Boy release from 1990, developed by Irem. It arrived during the handheld's early years, when developers were still exploring what the small screen could do with RPGs and adventure games. The game stands out for its supernatural theme and recruitment mechanics, offering a different flavor from the more common fantasy or sci-fi titles of the era.
You control a young boy who must cleanse a haunted castle by battling yokai, Japanese spirits and monsters. Your main goal is to explore the castle room by room, defeating enemies and recruiting some of them to learn their abilities. Signature mechanics include using a bow for ranged attacks, swapping between recruited spirits to access unique skills, and navigating maze-like floors filled with traps and secrets. The pacing is deliberate, and the difficulty can be unforgiving if you rush into encounters unprepared. It feels like piecing together a strategy as you go, deciding which spirits to befriend and which to destroy.
