Tachibana Yuu (立花ゆう Tachibana Yuu?) is a minor character in KiraKira☆Pretty Cure A La Mode. He is a jovial scientist who caused a revolution in the world of sweets. He is also the author of the book titled "The Science Of Sweets" that Himari always carries with her.
An older man with grey hair in a distinctive U shape and a grey mustache. At work he wears a white lab coat over a white shirt with a red tie and grey slacks. When going out, he replaces the lab coat with a grey suit, a beige jacket and a brown hat. He wears round glasses that often hide his eyes.
While he may appear eccentric at first, he is really a jovial man who is passionate about sweets and science. He acts like a mentor to Himari, sharing her passion for sweets and kindly encouraging her in finding what she wants to do.
Tachibana first appears in episode 28 when he visits KiraPati and is impressed with the delicious sweets there. He finds out that Himari is as passionate about sweets and science as he is, and decides to quiz her on her knowledge to see if she would make a good assistant for his show. Himari passes the quiz, but is afraid she wouldn't be a good assistant. Tachibana then tells her she should come to find out the secret behind sponge cake. Himari becomes an assistant on his "Great Sweets Science Experiment" show in Ichigozaka. Together they manage to make a giant sponge cake, but unfortunately it collapses soon after baking. Tachibana calls the experiment still a success though because it was thanks to Himari's dedication and love that they could get that far. After the battle with Grave, Tachibana wakes up to find the KiraPati girls making cake pops from the leftover sponge cake, and compliments them on this good idea.
In episode 43, Himari is assisting Tachibana again in his Cooking Research Institute, and he compliments her diligent note-taking and research. She then tells him about her audition for a sweets program on TV and that she wants to tell people about the wonders of sweets just like Tachibana. Although she is a little timid, he encourages her to take up new challenges like that, remarking that that too is very much like her. Later, during the battle with Elisio, Custard shows him a movie of her dreams for the future. One of the segments in it shows Himari doing a sweets experiment together with a group of children in Tachibana's lab.
