Fifth season of .

Takaya Ougi is just a typical high school guy who wants nothing more than to protect his best friend and live a normal life. Enter Nobutsuna Naoe, an older man who informs Takaya that he is in fact the reincarnation of Lord Kagetora. Naoe, himself a possessor, awakens Takaya's abilities to exorcise evil spirits and fight the Fuedal Underworld. While most possessors remember their former lives before being reincarnated, Takaya does not. Naoe is thankful for this, considering his passionate and abusive past with his Lord Kagetora. As Takaya improves his abilities, he also begins to remember what Naoe did because of his love for him. Meanwhile the dark forces of the Hojo and Fuma clans begin their attack as the Fuedal Underworld descends upon the living world.

Atop a hill overlooking a seaside port sits a boarding house named Coquelicot Manor. Since the building is run by her family, Umi Matsuzaki carries out many of the duties involved in managing the small establishment, such as preparing meals for her fellow boarders. When she isn't at home, she is a student at the local high school—one that is currently dealing with a small crisis.

In anticipation of the upcoming Olympic Games, a beloved old clubhouse is set to be demolished to make way for a modern building. As a result, a large part of the student body has banded together, working tirelessly to prevent this from happening. Umi finds herself helping the newspaper club to spread information about this cause where she befriends Shun Kazama, whom she gradually begins to fall in love with. But Shun is an orphan who doesn't know much about his origins, and when the two begin searching for clues to the boy's past, they discover that they may have a lot more in common than either of them could have thought.

Aside from her deep passion for eating cakes, the clumsy Ichigo Amano has never been successful at anything. After an encounter with Henri Lucas, a famous patissier, Ichigo's amazing tasting abilities—although unbeknownst to her—are discovered. Recognizing her talent, Henri offers her the chance to attend St. Marie Academy, a prestigious culinary school which specializes in desserts. In spite of the fact that she is a beginner lacking skills, thanks to Henri's recommendation, Ichigo is placed in the topmost group with the "Sweets Princes." The princes, famous throughout the school for their magical treats, are Sennosuke Andou, an expert in traditional Japanese sweets; Satsuki Hanabusa, with a flair for candied flowers; and Makoto Kashino, a gifted chocolatier. Ichigo and the Sweets Princes, each accompanied by their "Sweets Spirits"—fairies who make patissiers' dreams come true—all work towards their goals in the competitive world of sweets.
