Anime News Network's merchandise coverage sponsored by Tokyo Otaku Mode

Studio Trigger has its share of iconic anime girls from its recent works. Luluco, Akko Kagari, and Ryūko Matoi. On top of the stars of the company's anime works, Trigger also has three mascot girls, Trigger, Muzzle, and Spring, who are often the subject of guest artwork on the company webpage. The girls starred in an anime short earlier this year to celebrate the studio's fifth anniversary.
