Mirei Kiritani is a Japanese actress, model, and voice actor known for her work in live-action film and television as well as her contributions to anime and video game voiceover. Born on December 16, 1989 in Chiba, Japan, she began her career in entertainment as a model and gradually expanded into acting roles before taking on voice work in major animated productions and video games.

While Kiritani is primarily recognized for her performances in live-action dramas and films, she has also voiced characters in several notable anime and video game projects. One of her earliest voice roles came in 2012 when she voiced Kaoru Kōda in the anime film Detective Conan: The Eleventh Striker. That same year, she provided the voice for Maya Fey, known as Mayoi Ayasato in the original Japanese version, for the crossover video game Professor Layton vs. Phoenix Wright: Ace Attorney. This role marked her entry into the world of video game voice acting, connecting her to the popular Ace Attorney franchise.

In 2015, Kiritani voiced the female protagonist Meer in the video game Dragon Quest Heroes, a title developed by Koei Tecmo and published by Square Enix. Her casting alongside Tori Matsuzaka, who voiced the male hero Akuto, was announced in Japanese media as part of the game's promotional campaign.

More recently, Kiritani contributed to the long-running Anpanman franchise. In 2023, she voiced the character Roboly in the anime film Soreike! Anpanman Roboly to Pokapoka Present, the thirty-fourth entry in the Anpanman film series. This film commemorated the thirty-fifth anniversary of the Sore Ike! Anpanman television series. In the film, Roboly is a robot who travels to Anpanman World to learn something important, and Kiritani's performance brought this character to life.

Beyond her voice work, Kiritani has appeared in a range of live-action adaptations of popular manga and anime, including the role of Ritsuko Takahashi in the live-action drama Jigoku Sensei Nube, Mayoi Ayasato in the live-action Ace Attorney film, and Aguri Yukimura in the live-action film Assassination Classroom: Graduation. While these roles are live-action performances rather than voice acting, they demonstrate her longstanding connection to anime and manga properties. She has also worked as a news anchor for NTV's News Zero program from 2012 to 2018.

Kiritani's voice acting career, though more limited than her on-screen work, has allowed her to participate in beloved franchises such as Dragon Quest, Detective Conan, and Anpanman, showcasing her versatility as a performer across different media.
