Mengo Yokoyari is a Japanese manga artist. She first drew attention with Kuzu no Honkai, a teenage chronicle serialised from 2012 to 2017, and since 2020 has drawn Oshi no Ko to a script by Aka Akasaka: the story of a doctor reborn as the child of an idol, a satire of Japanese show business that became one of contemporary manga's biggest successes. It appears in French from Kurokawa and in German from Altraverse as Mein*Star.
