The movie which is based on the same-titled novel by Akutagawa Award-winning writer Fujisawa Shu, features Ayano as Yatabe Kengo who holds the Godan rank in kendo but chooses to live a life filled with alcohol and works as a security guard at a train station's building due to an incident. One day, he happens to meet a senior high school student Hada Toru played by Murakami Nijiro who loves rap and is obsessed with writing rap lyrics. Kengo sees Toru's talent as a gifted kendo swordsman which inspires him to undergo training with the latter under a monk who holds the Hachidan where they later face off in the battle of destiny.
In order to prepare for the filming, Ayano went through two months of kendo and muscle training and even abstained from alcohol. As such, he was able to use his frustration built up over the period in a positive way during the filming. Maeda chipped in to praise her co-star for looking very cool during the kendo match scene. Murakami then revealed that he sprained his finger during their fight sequence and he was surprised by how quickly Ayano reacted by shouting for ice packs to be given to him once the scene was completed.
