Mengo Yokoyari left high school early in order to pursue her dream of becoming a manga artist. Since childhood, she had been passionate about drawing and creating stories through pictures. In 2009, Yokoyari made her debut with the series "Maken☆H Zemi!," which was published in Magazine WOoooo! and later compiled into the collection "Mokkai Shiyo?". After consistently contributing to the magazine, she received an invitation from a Futabasha editor to draw for one of their magazines. This opportunity led to her first serialized work, Haruwaka.
