This guide will be showing you the map of the Lost Gate and where you can find the keys in the game.
North Key (Genbu Star Chart)
East Key (Seiryu Star Chart)
West Key (Byakko Star Chart)
Hidden Key (Koryu Star Chart)

And every single one of them can one-shot you if you’re not careful/overpowered enough.
Even on normal difficulty.
