Ikki Tousen - S04

After their alliance triumphs over Kyoushou Academy at the Battle of Chibi, Nanyou Academy under Sonsaku Hakufu and Seito High School led by Ryuubi Gentoku find little time to celebrate. A mysterious presence emerges from the battlefield, hinting at new turmoil. Meanwhile, a lone figure arrives at Kyoushou's gates-a high school girl with a ponytail, dressed in a jersey and carrying a rucksack. She effortlessly overpowers the academy's defenders and seizes the P.A. system, declaring, "I am Bachou Mouki of Ryoushuu! Sousou Moutoku, face me!" The fragile peace from Chibi is already crumbling. Though weakened, Sousou Moutoku is quickly regaining strength. And now, a fresh threat looms as Nanban High School enters the fray.
