Hari Tokeino is a Japanese shōjo manga artist known for creating the long-running series School Babysitters, which was adapted into an anime television series. Born on February 21, 1979, in Chiba Prefecture, Tokeino works under a pen name that translates to Hand of the Clock, and she often draws herself as a clock in author illustrations. Her career began in the early 2000s with the one-shot Santa no Iru Machi, which earned her a Best Rookie award. Tokeino made her series debut with Me & My Brothers, which was serialized in Hakusensha’s LaLa magazine from 2004 to 2009 and collected into eleven volumes. This series established her focus on family dynamics and gentle comedy, following a young girl who moves in with her four overprotective half-brothers.

Tokeino is best known as the creator of School Babysitters (Gakuen Babysitters), which began serialization in LaLa magazine in 2009 and remains ongoing. The manga was adapted into a thirteen-episode anime television series produced by Brain's Base, which aired from January to March 2018. An original video animation episode was later released with the seventh Blu-ray and DVD volume of the series. The story follows brothers Ryuichi and Kotaro Kashima, who are taken in by the chairman of an elite academy after losing their parents; in exchange for housing, Ryuichi works in the school’s daycare center, leading to heartwarming interactions with the children and their families.

Beyond her two major serializations, Tokeino has produced several shorter works. Hitai ni Mikazuki, a one-volume collection of short stories, was serialized in LaLa DX and LaLa Special between 2005 and 2006. Gyakuten Honey, another one-volume work, ran in the same magazines in 2009. She also wrote a one-shot titled Love Log in 2012. Her works are published under Hakusensha’s Hana to Yume Comics imprint, and several have been licensed for English release by Tokyopop.

Tokeino’s artistic identity centers on themes of family, chosen kinship, and the warmth found in everyday life. Both Me & My Brothers and School Babysitters explore what happens when unconventional family structures form due to loss or circumstance, emphasizing mutual care and emotional healing through gentle humor. Her art style is characteristic of shōjo manga, with expressive character designs and a soft, approachable aesthetic. In the manga industry, Tokeino is recognized as a consistent contributor to LaLa magazine, one of Japan’s leading shōjo publications, with School Babysitters becoming one of its signature long-running titles. Her work has been translated and published internationally, including English editions in North America and French editions through Glénat.
