Kantai Collection character personifying the nameship of the Matsu-class destroyers of the Imperial Japanese Navy, which were subdivided to the Matsu and Tachibana subclasses which numbered 18 and 14 completed ships respectively. Her name means "pine." Her illustrator is Watanabe Akio, who is best known for his work in Popotan and the Monogatari series, as well as the 2020 anime version of Higurashi no Naku Koro ni.
Matsu has long green hair which is draped over her left shoulder with antenna hair and green eyes. She wears a serafuku composed of a khaki sailor shirt with a gray sailor collar and black corset (with an anchor zipper pull tab), a gray pleated skirt, and black-toned pantyhose as well as black gloves, a single knee pad over her left knee, and a black choker. Her machinery consists of a handheld adapted turret, a torpedo launcher beside her right leg, as well as a smokestack and several other items behind her back.
Remarkable for Matsu is her damaged CG which is reminiscent of the infamous Myoukou pose -- said CG shows her in the process of sustaining damage, disintegration of her machiney and clothing, and feeling the brunt of said damage as if hurting.
The historical destroyer had a very short career; she was sunk during her first and only battle three months after she was completed by the combined firepower from three Fletcher-class destroyers (USS Cogswell, Ingersoll , and Knapp) on August 4, 1944, her own firepower being no match to those of the other side. This was after completing a convoy mission to Chichijima and en route back; her convoy was spotted by planes belonging to the US Navy's Task Group 58.1, resulting in an airstrike and subsequent face-off between destroyers.
