She has a shy, nervous, and "girly" personality, which makes an odd pairing with her "younger sister" Uranami, since Uranami's lines make her sound reliant upon the guidance of the older Isonami in spite of Isonami being generally far less sure of herself than the rather enthusiastic Uranami.
In her combat gear, she wears her rigging as a form of backpack, while carrying two torpedo mounts on both sides of her thighs. Her twin-cannonturret is wrist-mounted.
She later gains a kai ni form on May 13, 2022 that lets her use the standard Special Type kai ni uniform.
History
In real life, Isonami was, like most IJN destroyers, pressed into transport duty as well as performing escort duty, rather than seeking out the enemy for most of its career. Isonami did not distinguish itself except in being present in larger battles and colliding with Uranami during the Battle of Midway. Isonami was ultimately sunk by USS Tautog while rescuing survivors of a torpedoed transport ship on April 9th, 1943.
