Hauenkua

Hauenkua serves under Amururineuruka Kuuya and has roughly the same status as Hien. He is entertained by war and suffering and has a somewhat psychopathic personality, however this all drains away when he feels his mortality, leaving him a panicked wreck.

Spoiler

He pilots a red Avu-Kamuu, with claws on each arm. It is also revealed that he has been working with Dii. During the final battle, he suffers a psychotic break and is killed by Hien.
