His OVA depiction is much different. Instead of a demon/human hybrid, Amano is a "beast-man" who spent 300 years hunting for the Chōjin. In this version, he is implied to have left his home realm of his own accord instead of being forced to like in the manga. He is also quite stubborn and determined to discover the identity of the Chōjin and wants the prophecy of the three realms being united in harmony to be made a reality more than anything. In addition, he develops a protective bond with Nagumo and Akemi and is genuinely horrified upon seeing the destruction and chaos that Nagumo causes while in demon form. During the final episode of the first OVA series, Amano desperately tries to appeal to Nagumo's human nature to no avail and sheds tears when he realizes that it is beyond his control. As the series goes on, Amano's faith in the prophecy is challenged constantly and eventually resolves to put an end to the Chōjin and preserve the three worlds as they currently exist. This contrasts greatly to his manga counterpart even though he displays a casual and anti-hero type attitude in both versions.
