A boss-type submarine enemy in [[Kantai Collection]], introduced in the Fall 2015 event, which focuses on the "Solomon Island Campaign":[https://en.wikipedia.org/wiki/Solomon_Islands_campaign].

Like many "princess-tier" [[abyssal ship]], she has voluminous [[very_long_hair|extremely long hair]] and wears a flowing white [[dress]]. To her right is a large metal structure shaped like the bow of a WW2-era submarine, except with a trademark [[teeth|toothy]] maw and glowing eyes.  She holds or swims near multiple [[torpedo]]es. A pair of tubes also seem to connect into the back of her thighs or butt.

Unlike most of the "princess" or "oni" characters, there doesn't seem to be an obvious single historical reference that Submarine Princess represents, instead seeming to embody all submarines. She has, however, been considered "[i]Albacore[/i] Princess" by some, due to the USS [i]Albacore[/i]'s notorious record against the IJN, although [i]Albacore[/i] spent the Solomon Campaign sinking transports, and wouldn't get most of the kills that made the ship notorious until afterwards. There has also been the suggestion that she is "I-27":[https://en.wikipedia.org/wiki/Japanese_submarine_I-27], an unimplemented Type-B1 submarine (the same class as [[i-19 (kancolle)|Iku/I-19]]) who sank in the area where she is encountered as a boss.
