Diesel

Diesel is a Nikke who is the leader of Infinity Rail, a squad that handles the AZX train in the Ark. Before she became a Nikke, Diesel used to work for AFX along with her two future squad mates, Brid and Soline. Tragically, AZX was sabotaged, claiming nearly all the lives on the train, including Diesel little brother. As a result, most of the girls were turned into Nikke's along Diesel, Brid, and Soline to work on the new AZX. Despite her traumatized past, Diesel holds her head high and often puts on a smile for everyone. The two things that help Diesel remember her little brother are strawberry candies that he used to love and continuing to work for AZX since he always loved trains.
