Sendai loves night battles mainly because most of her operations were night attacks such as Invasion of Malaya, Battle off Endau, Battle of Guadalcanal as well as Battle of Empress Augusta Bay. In her final battle, she was set afire at 0050 hrs but remained afloat until 0430 hrs before sinking.

Though the origin of her name is a proper noun of river, 鬼怒 literally means "Ogre's Rage", and this accounts for her unique pose and character.
Tama
Sunk by USS Jallao northeast of Luzon at 21°23′N 127°19′E, 25 October 1944.
Her in-game voice is very soft spoken, so in terms of temperament Tama is usually depicted as rather laid back. True to her cat-like nature she is often portrayed sleeping or lounging, especially under a kotatsu. She is most frequently paired with her sisters, especially Kuma.
