In Code Vein II , you step into the role of a Revenant Hunter, wielding extraordinary powers alongside a mysterious Jail artifact embedded in your back. This device allows you to harness the innate abilities of Revenants in battle. Your journey begins as you travel into the past, where you must earn the trust of legendary heroes and uncover the key to preventing the world's collapse in the present.

You won't face this dangerous frontier alone. Powerful allies known as Partners fight at your side or bolster your abilities. Each Partner unleashes their own attacks and wields a unique power called Formae, used for both offense and support. Blood absorbed through their special Drain attacks is shared with you, restoring a portion of your vital resource known as Ichor.
