Isolated Island Oni is an enemy [[abyssal ship]] found in [[Kantai Collection]]. She was the boss of the fifth event map during the Spring 2014 event.

She is depicted with [[very long hair|very long]] [[black hair|black]] hair, [[glowing eyes|glowing]] [[red eyes]], [[small breasts]], two [[horns]], a [[bonnet]], and a frilled [[gothic lolita]] dress with detached sleeves. She also wears [[bodystocking]] and has two spikes protruding from her upper back like [[Airfield Princess]].

She's often portrayed as a [[hikikomori]] in fanart ([i]Isolated[/i] Island Oni). Her nickname amongst fans is "Ritou" (りとう) which is taken from the first two kanji in her name. Also, before [[Northern Ocean Princess]] was introduced, she was the youngest looking [[abyssal ship]], looking more like a 14-15 year old in comparison to the rest of the abyssal fleet whom look 18 and older. In fact because of this she originally had the Pixiv tag "敵艦隊のチャイドル ([i]Teki kantai no chaidoru[/i], lit. "Enemy fleet's child idol") before it was nearly taken over by [[Northern Ocean Princess]].

She is based on "Wake Island":https://en.wikipedia.org/wiki/Battle_of_Wake_Island and is voiced by [[Ogura Yui]].
