Hayatemaru (疾風丸) is a character in the anime and manga series Battle Spirits Sword Eyes.
Hayatemaru is a giant brown and white eagle. Oddly, he has black hair and eyebrows. He wears a ninja headband and green scarf.
Although he can't speak, he can clearly understand humans, and behaves more like a human than an animal. He cares about Hagakure.
Hayatemaru is a bird and Hagakure's friend. He is large enough to be ridden on and appears when summoned.
He learned to fly in order to save Hagakure from falling off a bridge.
