Mr. Sandal (サンダルさん, Sandaru-san) is a mysterious foreign-looking man who wanders around Manoyama. His true identity is Alexandre Cena Davis Celibidache, a vagabond artist known for his paintings and music.
Mr. Sandal is a young man with shoulder-length blond hair and blue eyes. He wears a khaki cloak over a black turtleneck sweater, denim pants and brown sandals. He is often seen carrying a light brown bucket bag, as well as musical instruments, notably a ukulele and a harmonica.
Adding to his mysterious character is his tendency to speak in vague lines in fluent Japanese. Although seemingly friendly, his unusual personality makes him somehow unapproachable.
Mr. Sandal first appeared as a lone passenger in Takamizawa's last bus trip during the night where Yoshino Koharu found out about her year of duties as queen of the Chupakabura Kingdom. He also appeared personally to buy a box of manju from Yoshino after watching the video she and her friends made to promote the manju buns, commenting that manju "were scary". While Yoshino was interviewing the townsfolk about their sentiments of Manoyama, Mr. Sandal is seen sketching a harvested white turnip.
- Mr. Sandal usually speaks in the preview of the next episode, revealing his accurate pronunciation of English words.
- Due to his music talent, eccentricity and name similarity Mr. Sandal's real name could be an indirect reference to the famous Romanian composer and conductor, Sergiu Celibidache (1912-1996).
- "Alexander S. D. Celibidache" is also the pseudonym of the P.A. Works staff, the makers of Sakura Quest.
- Considering that the title of series comes from a novel that Sandal wrote in the final episode, its pretty much a given that they are the same person.
