Aki (アキ) is one of the supporting characters in Girls und Panzer: Der Film.
Aki is a student at Jatkosota High School and is the gunner/loader of a Finnish BT-42.
Aki is a small girl with light blond hair and light green eyes.
Just as Mika can be seen as the counterpart of St. Gloriana Girls High School's Darjeeling, Aki can be thought of as the counterpart of Orange Pekoe. Both are small girls who have to deal with eccentric commanders, with Aki often frustrated or confused by Mika's cryptic statements.
Like Orange Pekoe, she also seems to be the most grounded and level-headed girl on her team.
Aki's first appears alongside Mika observing the Ooarai Girls High School/Chi-Ha-Tan High School Girls Academy vs Pravda Girls High School/St.Gloriana exhibition match, wondering why they weren't participating on it. She later joins the Ooarai Compound Team in their fight against the Selection University Strengthening Team. Along with Mika and Mikko in their BT-42, she helps the Hetzer, CV.33 and the Type 89 take down the Karl-Gerät by distracting and eventually knocking out its entire Pershings escort. She is later seen with Mika and Mikko on their boat, having left before the conclusion of the match. However, she does observe the victory of the Ooarai Compound Team on a small television set on-board.
During their boat trip after the annihilation match, the three girls end on a desert island with their boat broken, their, she makes use of survival techniques, such as lighting a fire with flint and steel for cooking.
Motto Love Love Sakusen Desu!
Mika has a few cameos with her teammates on MLLSD, showing moments of their passage in the desert island, their visit to Ooarai with other schools to celebrate the Annihilation match victory and their daily lives together.
Like her teammates from Jatkosoka, she might be inspired in one of The Moomins, original Swedish Mumintrolls characters, with Aki being Moomintroll.
