Mari Akutsu is a name used by the Japanese voice actor Omi Minami for specific roles, particularly in adult animated projects. Minami is a well-established voice actor in the anime industry, born on July 13, 1968, in Tokyo, Japan. While Minami has portrayed a wide array of characters across many popular series under her primary name, the alias Mari Akutsu is most famously associated with the character Miko Mido in the La Blue Girl series of original video animations.

The role of Miko Mido, the protagonist of the erotic horror-comedy La Blue Girl, is the defining credit for the Mari Akutsu alias. Minami provided the voice for Miko under the Akutsu name in the original 1992 La Blue Girl OVA series. She also voiced the same character in the subsequent OVA series Lady Blue, also known as La Blue Girl EX, which was released in 1996, again using the Mari Akutsu pseudonym. These performances remain her most recognized work under this specific alias.

In addition to these central roles, the name Mari Akutsu has been credited for providing additional voices in the La Blue Girl series, contributing to the broader cast of characters in that world.

As Omi Minami, the voice actor has a much more extensive career with many notable achievements. She is widely recognized for lead roles such as Ruri Hoshino in Martian Successor Nadesico, Hyatt in Excel Saga, and Euphemia li Britannia in Code Geass. The use of the Mari Akutsu alias is a common practice in the Japanese entertainment industry for voice actors who take on roles in projects with adult content, allowing them to separate this work from their mainstream filmography.
