Abara is a dark science fiction manga by Tsutomu Nihei set in a futuristic world where humanity faces extinction from mysterious, monstrous entities known as Gauna. The story follows Kudou, a young man who can transform into a powerful armored being called a White Knight to fight these creatures, while also uncovering the secrets of his past and the true nature of the Gauna. Readers enjoy it for its intense, visceral action, Nihei's signature sprawling and decaying architectural art style, and the cryptic, atmospheric storytelling that creates a sense of desperate survival in a doomed world.
