Aicho, also called Aicho the Sky (空の藍朓 Sora no Aichō?), is the former 10th Ninku corps (酉忍 Tori-nin, the rooster Ninku) captain and has extremely strong legs with an attitude to match, enabling him to cover large distances in a single bound and cause big damage on enemy machinery through his techniques. He also hates women, as this can be seen in his attitude towards Touji's sister, who has a crush on him. He also considers Touji an idiot. - From Wikipedia
