About This Game

Historical connections are clues to powerful combos.

Inga Chronicle is a deckbuilding roguelike built on authentic Japanese history — from the Asuka period to the Bakumatsu era. Every card represents a real historical figure, policy, or event. Causal Combos link cards inspired by those figures, policies, and events.

This isn't a game with a Japanese coat of paint. Its content is derived from Japan's national high school curriculum — the same material tested in university entrance exams. Knowledge of historical relationships gives you clues to useful card combinations.

Example: Land Reform Combo

"Taika Reform" + "Handen-Shuju Law" + "Konden Einen Shizai Law" + "Rise of Shoen Estates"

These are in-game card combinations. The order shown does not necessarily represent a historical timeline or a direct cause-and-effect chain.
