After 17 years of learning Ukiha Divine Wind Style Swordplay in the mountains, Yoichi Karusuma is ordered to experience life in the city with the Ikarugas by his father, as he has nothing more to teach him. After he arrives in the city, Yoichi is ridiculed by Washizu for his samurai clothes and easily defeats him. The Ikarugas wait in the city to pick up Yoichi. Later in the day, Yoichi chases after a thief, causing mayhem in a shopping centre. During his pursuit, Yoichi unknowingly encounters the Ikarugas in embarrassing situations. After he successfully stops the thief, he returns a lost Kagome to Ibuki. Outside the shopping centre, Ibuki asks Yoichi if he is Yoichi. He agrees. The police arrest Yoichi for causing mayhem but releases him afterwards. Ibuki takes Yoichi to her dojo and introduces him to her sisters

Yoichi is invited to a date by Hinagata Yui. Ibuki, afraid that Yoichi will damage the Soaring Wind reputation, invites Yoichi to a practice date. She gets him to wear "normal" clothes during the date and takes him to a toy shop, where she shows keen interest in a plushie. Meanwhile, Ayame and her friends are buying clothes. They comment about Ayame's breast size to her chagrin. She sees Ibuki and Yoichi together and follows them. Ibuki and Yoichi goes bowling. They are secretly watched by Ayame, Chihaya and Kagome. Washizu and Torigaya see Ayame walking out of the bowling place and Washizu thinks about Ayame's possibility for being his sister-in-law. Meanwhile, while walking along a street, Ibuki attempts to take Yoichi's hand. He turns around and she shies away, tripping over a stone and they both fall into a fountain. Yoichi gives Ibuki the plushie she wants and thanks her for the practise date. Ibuki realizes that this is not a real date and rushes off to buy drinks, with Chihaya and Kagome hiding in bushes, watching them. Hinagata meets Yoichi near the fountain and Yoichi declines her request for a date. She fights him with a three section staff. Yoichi ruins Hinagata's uniform and she runs away. Meanwhile Ibuki is confronted by two men who criticise her for being with Yoichi. Yoichi, Chihaya and Kagome hear Ibuki's voice and rush to her aid to find that she has defeated her assailants.

Yoichi, Kagome, Chihaya and Ayame arrive at the Saginomiya residence, a pagoda-shaped castle. They cross the river surrounding the castle using a raft built from surrounding trees. Ukyou orders Sakon to chase Yoichi's group away. She reluctantly accepts. Yoichi's group enters the castle and sees Sakon standing on the top of a staircase. She reveals that Ukyou plans to marry Ibuki today. Then Sakon's maids attack the party, to which Yoichi successfully blocks. Sakon's use of sleeping gas backfires and causes her maids fall asleep. Yoichi pleads Sakon to return Ibuki. Sakon slaps Yoichi and dissapears. Yoichi's group encounter more guards. Luckily, Washizu, Tsubame, Angela and Torigaya intervene. Torigaya gives Washizu his metal-spiked gloves. Yoichi, Kagome, Chihaya and Ayame chase Sakon into the chapel, where Ukyou is preparing his wedding. Ukyou and Ibuki escapes through a hidden platform. Yoichi follows Ukyou to the rooftop, where they fight each other. Ibuki recovers her memory but falls off the roof. Both Yoichi's group and Ukyou attempt to follow but Ukyou is held back by Sakon hugging his legs. Yoichi's group falls into a river. Yoichi grabs onto Ibuki's breast to stop himself from drowning. Ibuki makes him fly with one punch. Yoichi sent a letter to his father of his wishes to stay at the Ikaruga dojo.
