Ikki Tousen sæson 4

Nanyou Academy, led by Sonsaku Hakufu, allied with Ryuubi Gentoku's Seito High School, have together won a resounding victory over Sousou Moutoku's Kyoushou Academy at the Battle of Chibi. However, there is no rest for the weary as a figure stirs from within the site of the battle...

At the same time, another figure stands before the gates of Kyoushou. Upon closer inspection, it turns out to be a high school girl with a ponytail, wearing a jersey and toting a rucksack. She smashes aside all Kyoushou fighters who try to stop her. Occupying the academy's P.A. room, she issues her challenge: "I am Ryoushuu's Bachou Mouki! Fight me, Sousou Moutoku!"

The peace won at Chibi is short-lived. Despite the recent setback, Sousou Moutoku is fast recuperating his power. In addition, a new faction arises in the form of Nanban High School.
