Aicho  

Aicho the Sky, 藍朓

Aicho, or Sky Blue Aicho (空の藍朓 Sora no Aichō?), was once the captain of the 10th Ninku corps (酉忍 Tori-nin) and is known for his powerful legs and strong attitude. He can leap great distances in a single bound, inflicting significant damage on enemy machinery with his techniques. Despite this, Aicho has a deep dislike of women, which is evident in his treatment of Touji's sister, who harbors feelings for him. Additionally, he views Touji as an idiot.
