Diouc Koma, born Dioucounda Koma on August 30, 1980, in Bamako, Mali, is a French-Malian actor and screenwriter who has built a substantial career in French dubbing. While he is the regular French voice for numerous Hollywood actors, his work in animated series, rather than Japanese anime, defines his contribution to voice acting.

Koma began his acting career at a young age, making his first on-screen appearance at fifteen in the film Le Plus Beau Métier du monde. He trained at the Conservatoire d'art dramatique du 10e arrondissement in Paris. His career spans live-action film and television, theater, and extensive voice work for French dubs of American and international productions. Since 2001, he has been active in dubbing, covering a wide range of roles in films, television series, animation, and video games. He is also known for his critically acclaimed live-action role in the film Un homme qui crie, which won the Jury Prize at the 2010 Cannes Film Festival.

In the context of voice acting for animation, Koma has voiced characters in several prominent animated series. One of his key roles is Lance Strongbow in the French version of Tangled: The Series. He has also voiced Finn in the French adaptations of various Lego Star Wars and Star Wars: Forces of Destiny animated projects. His other animation credits include roles in Lascars, Atomic Puppet, Abraca, Kizazi Moto: Generation Fire, and the French dub of Invincible, where he voiced Theo. In feature animation, he has provided voices for French dubs of films such as Igor, Monster House, Trolls World Tour as Prince D, and Soul as Curley.

Koma is recognized as the regular French voice for several major actors, including John Boyega, Donald Glover, Michael B. Jordan, Corey Hawkins, Brandon T. Jackson, and Jessie Usher. Beyond television and film animation, his voice work extends to video games. Notable video game roles include Delford Iraq Wade in Watch Dogs, Finn in Lego Star Wars: The Force Awakens, Officer Chris Miller in Detroit: Become Human, and Mark Nestor in The Dark Pictures Anthology: The Devil in Me.

The role of Ishikawa, as mentioned in the query, was performed by Koma in the French dub of the 2017 live-action film Ghost in the Shell, where he voiced the character portrayed by Lasarus Ratuere.
