A next-generation sport where fighters turn their very souls into blades and battle: Blade Spirit Chronicle. A young man named Kirino Yaba had laid down his sword for certain reasons and was living out quiet, ordinary days working as a private security guard. Then one day, while on duty, he meets Kirika Saimonji, a rising young athlete with a promising future.

"Please become my coach!!"

After witnessing Yaba’s swordsmanship, Kirika earnestly begs him to train her. Though hesitant at first, Yaba is gradually moved by her passion. As he begins to recognize the lingering fire for Blade Spirit Chronicle still burning within him, the clock that had long since stopped in his heart finally starts ticking once more!
