Main characters ; : :A second-year 10th-grade student. Daughter of a great pâtissier and a brilliant scientist. While relatively skilled at cooking and tasting, her academic performance is somewhat random (for instance, when a science test question concerning reflection asked how her reflection in a mirror would look, she responded "It looks cute"). Subtle hints she has feelings for Shun. She first slipped into the past by touching a book she stumbled upon in Shun's room which was passed to him by her father. Sometimes, she must change clothes due to skirts being unrefined in the past. She was later captured by Mikage and forced to slip back into the past to find Eiji after finding out about the machine. Her father saves her amid a time paradox but manages to return safely to the future after Shun saves them. She became a scientist in the future, discovering the time machine, following her father's footsteps. ; : :Mari's second-year classmate and best friend and Shun's younger sister. She has a crush on her classmate, Futa. She is the first person to witness Mari slipping back in time and informs Shun about it. Waka accidentally slipped back into the past along with Mari and was unable to return. She panicked while she was alone in Faraday's era, which is different from how Mari reacted when she first slipped back to the past. Unlike Mari, Waka earns top scores in history and English. ; : :A third-year 12th-grade Waka's older brother who plans to become a doctor. Eiji passed a book to him and Mari stumbled upon it, allowing her first time slip to occur. He found out that in the future, along with Mari, he would become a scientist who discovers the time machine. ; : :Akira's husband. Mari and Rika's father. A passionate scientific researcher, he tends to become excessively engrossed in his studies and expeditions; the day after his wedding he disappeared for weeks without any contact and hasn't seen or contacted his wife or daughters in three years. Found him to be in most of the past traveled when Mari slipped back. He slightly helped Hertz realize his dream. Eiji discovers in one journey to the past that Mari was captured by Mikage, and tried to save his daughter only to have a time paradox occur in the midst of it. ; : :A member of the soccer team and a classmate of Mari and Waka. Despite being oblivious, Waka has a crush on him. ; : :The main
antagonist of the series. A cold-hearted businessman who is interested in the time machine, the "matter transporter", which was stored in the laboratory. He captured Mari, her mother, and the Mizuki siblings inside the lab after discovering the machine in the basement. He forces Mari to return to the past with him in order to locate Eiji, only resulting in himself being trapped in Edison's era due to the occurrence of a
time paradox in the final episode. Edison took pity on Mikage when he became a part of
Edison's pioneers.
