Kimi no Katana ga Oreru made: Gekkyuu Matsuri no Koigataki

Synopsis

The time is the Edo era! Tsukimiya Matsuri, a girl widely admired for her beauty, is faced with a big problem: the guy she likes, Tsukimiya Yonosuke, is not interested in her. She tries to demurely confess her love to him, but he doesn't take her seriously... because they grew up together ever since they were small children, and he sees her more like family! What a shame, Matsuri-chan...! However, Matsuri has a bigger reason for wanting to attract Yonosuke's attention. Yonosuke is trying to avenge his former love's murder, ready to give up his own life to fight the Shogun. Trying to stop him from wasting his life on reckless revenge, Matsuri decides, "I will become his reason for living." In order to take his mind off the path of revenge, she wants to fill his head with her love for him instead. Even if the boy thinks of her as "family," the dedicated and enthusiastic Matsuri will not be deterred! This is the start of a gutsy Oedo romantic comedy and action drama! Don't give up, Matsuri-chan! (Source: Sunday Webry, translated)
