The Lost Child is a first-person dungeon-crawling RPG following journalist Hayato Ibuki as he investigates supernatural events tied to angels and demons.

Exploring grid-based labyrinths and fighting in turn-based battles, you capture creatures called Astrals and raise them as party members. Its dark, occult-tinged story mixes urban mystery with mythological themes. Dungeon design rewards steady exploration and strategic party building against increasingly dangerous foes.
