Karasuma Yoichi (voiced by Nobuhiko Okamoto) is a simple child who grew up in the mountains. His only wish is to learn first-class swordsmanship. Every day, he practices hard to achieve his wish. On this day, his father suddenly told Yoichi that if he wanted to continue to improve his swordsmanship, he must go to the bustling city to find new challenges. Yoichi followed his father's advice and set off. Yoichi, who had just arrived, stayed at the Kakaguya Dojo, but here, he did not encounter any challenges, but met four beautiful young ladies in the dojo. Faced with the sudden visitor, the eldest daughter Ibuki (voiced by Rina Sato) had an instinctive resistance, but as she got to know him better, she gradually developed a good impression of Yoichi. The second daughter Ayame (voiced by Haruka Tomatsu) also has a different feeling for Yoichi, but she ranks behind her sister in everything she does. Can she win the first place in love this time? And this complicated feeling has become an interesting thing in the eyes of the third daughter Chihaya (voiced by Yurika Tamura). The youngest child Kagome (voiced by Hanazawa Kana) does not have the good skills of her sisters, but the arrival of Yoichi also makes her understand the value of her existence. In this way, in the Kakaguya Dojo, what kind of future will Yoichi face tomorrow?
