This year's 41st issue of Kodansha's Weekly Young Magazine revealed on Monday that Meguru Ueno will launch a new manga titled Gal-Sen in the magazine's 42nd issue on September 13. The manga will follow a big-busted, sexy, and tanned "gyaru/gal" who is a teacher, and she has a sadistic side.
Ueno launched the five-volume Does a Hot Elf Live Next Door to You? (Otaku no Tonari wa Elf desu ka?) manga in July 2019, and the series ended in March. Seven Seas Entertainment is releasing the manga in English.
