Having won the 63rd National Sensha-dou tournament, the girls from Ooarai High managed to prevent their school from closure by the Japanese Ministry of Education. However, new troubles loom on the horizon: a ministry official argues that the deal was not legally binding and that the Ooarai school carrier is to be decommissioned. Students and their families are frustrated with this injustice and overwhelmed with despair; it seems little can be done to save the school.

Their last glimmer of hope is a proposed match against the All-Stars University Sensha-dou team, consisting of the most talented students from all over the country. Despite Ooarai being severely outnumbered and clearly outclassed, they accept the challenge.

Sequel of Touken Ranbu: Hanamaru.

When humanity is driven to the brink of despair by an alien threat called Pillars, a self-proclaimed god named Odin appears and bestows upon the people the power of "Valkyries"—battle maidens who pilot vintage aircraft called Hero Wings. Claudia "Schwertleite" Bruford is the ace of the European Valkyrie Wing. When Japan's S-class Valkyrie passes away in battle, Claudia is relocated to Japan as a replacement. However, with a dark record of being the sole survivor in every mission that results in being nicknamed "Grim Reaper," she suspects she already knows why she was chosen. Prepared to be shunned yet again, she arrives at the Tateyama Valkyrie Wing. Little does she know, her new comrades are a bunch of oddballs who have zero intention of accepting her dreadful nickname!
