A Kantai Collection character based on the 18th Yuugumo-class destroyer of the Imperial Japanese Navy. She was first seen on a preview for the game's 2020 calendar before being introduced in the 2019 Autumn event. Her name literally means "autumn frost."
Akishimo has short silver asymmetrical hair with a long left lock that gradiates to brown. On either side of her head, she wears a leaf hair ornament over her ear. Her outfit is similar to her sister ships - a school uniform with a long sleeved white shirt under a purple pleated dress and a blue bowtie around her neck. Like Hayanami before her, she wears grey or purple seamed thighhighs instead of a pantyhose in her base form. Her damaged CG reveals she wears orange underwear underneath her uniform.
The historical destroyer was sunk during an air raid by the United States Air Force on Manila alongside Akebono on November 14, 1944.
