is a student at T•A Academy for Girls, and the president of the school's Supernatural Research Club. Like many of the students at T•A, she seemed to have an admiration for Rei Hino. She first appeared in Act 15, when the disguised Koan created a rival club with a fortune-telling booth at the school festival. Kotono is also Kyusuke Sarashina's elder sister, and made a Sailor V button for her brother. Chibiusa liked it but Kyusuke refused to get her one, but after the two of them helped defeat the vampire Lilica Hubert, he had Kotono make a Sailor Moon button for her as well. She is voiced by Akemi Kanda in Sailor Moon Crystal and by Tara Sands in the Viz Media English dub.
