Père de Kiki is the French-localized name for the father of the protagonist Mami Sakura, who is referred to in the French version of the series as Kiki. In the original Japanese material, this character is named Jūrō Sakura, and the anime credits him simply as Papa. He is an artist by profession, working as both a painter and a part-time art teacher at a high school. He occasionally holds exhibitions of his paintings, although they do not sell especially well, and he is also known as a picture-book author, with a children's picture-book series to his name. His artistic work is closely tied to his home life, since he often asks his daughter to serve as a model for his paintings, paying her in the form of an allowance, and he sometimes hires professional models instead. The family's French ancestry runs through his side, and Mami's red hair is an atavistic trait inherited from his French great-grandmother.

In personality, Père de Kiki is warm, easygoing, and playful, with a gentle and somewhat whimsical manner. He is trusting to the point of comic contrast at times, as he and his wife hold Mami's classmate Kazuo Takahata in very high regard, and he tends to accept what Takahata says even when he doubts his own daughter's words. When Mami once asks him what he would do if he possessed psychic powers, he replies that he would absolutely hide the ability and tell nobody, an answer that carries particular weight because Mami has decided to keep her own powers a secret from him. His motivations are centered on his art: he pursues his painting seriously, holds exhibitions, and carries a desire to grow further as an artist, which eventually leads him to seek training abroad.

Within the story, he is a supporting presence who gives Mami an ordinary family life. He is unaware of her supernatural abilities, and she considers revealing them to him but ultimately refrains after learning that her French ancestors were persecuted as witches, making her fear how he might react. His profession brings him indirectly into several episodes, such as the story in which Mami uses her highly precise telekinesis to remove cancerous cells from a critic of her father's paintings. His key relationships are with his wife Naoko, with his daughter Mami, whom he affectionately calls Mami-kō or Mami-kun, and with Kazuo Takahata, in whom he places considerable trust as a reliable young person.

His development is modest but meaningful. In the anime, his personal arc culminates in the final episode, which centers on his decision to travel to France to study painting, and his departure serves as the closing event of the series. As for abilities, he has no supernatural powers; his talents are entirely artistic. He paints, illustrates picture books, and teaches art, and his daughter has inherited her own considerable drawing ability from him. His paintings earn him exhibition opportunities but only limited commercial success, and his overall role is that of a caring, slightly distracted artist father whose work quietly shapes the household he shares with his wife and daughter.
