A-Do 4

Hovering between life and death after shielding Eito from the army's bullets, Riko awakes in the same facility that Eito fought to escape. Colonel Tsujiura then reveals that Riko owes her life to an A-DO named Ewan and his miraculous healing powers. Back in the outside world, an extortionist cult learns of Ewan's existence and hatches a scheme to kidnap him. With danger now pressing on every side, Eito and Ewan must decide who holds the strings to their fates.
