Otogi Juushi Akazukin OVA

Long ago, the worlds of science and magic were separated and sealed away from one another. An otherwise ordinary boy, Souta Suzukaze, carries within his body the key capable of breaking that seal.

The witch Cendrillon seeks to seize this power, bringing danger into Souta’s everyday life. Akazukin and the silver wolf Val arrive from the magical world to protect him, drawing the boy into a struggle whose stakes reach across both realms.
