Tone is a heavy cruiser in Kantai Collection, notable in game stats terms for her high LOS stats and recon seaplanes.
As a character, she is notable for her old-fashioned militaristic speech patterns, and has a somewhat aggressive personality. She has long, brown hair in twintails with two white hair ribbon accessories. At least in official art, at least one strand of hair comes down between her eyes.
Her sister ship, Chikuma is a notable siscon.
Before upgrade, she wears a single elbow glove on her left arm that has a seaplane runway on it, a long green jacket belted at the waist (with some ambiguity as to whether it's acting as a short dress, or she's just wearing no pants), and asymmetrical legwear in the form of a thigh-high sock on her left (runway) side.
With battle kit on, all her turrets are on her right side.
After upgrade, she has a much more visually distinct appearance, wearing a shorter green jacket, a long black skirt with such extreme side slits as to make it a pelvic curtain, and no visible underwear (As far as the anime is concerned, she wears some form of extremely highleg panties, the straps being high enough to hide under her jacket). Many posts make light of the fact that she apparently wears nothing underneath a single loose piece of clothing...
