Dark Heart is an playable character in the Arcana Heart series, who appears in Arcana Heart 3 Love Max Six Stars XTEND as a DLC character. Little known about her origin, she is hailed from an unknown tragic future with a mission to travel back in time to the present-day, and find her primary target: Heart Aino.

Her Arcana is Love Prison Geist.


Dark Heart is Heart's exact opposite in appearance. She wears a black high school uniform with red and yellow straps on the arms, a pair of white gloves, a black cape, black boots accented with yellow buttons, rings on the top and yellow soles. She wears a black military cap with a red strap and a yellow heart symbol.

Like her good natured counterpart, she also has pink hair, but it is longer, reaching down to the back of her knees. She has a hair antenna under her cap. Her eyes are a reddish purple color instead of the orange eye color Heart has. She also seems to have a slightly curvier body compared to Heart.


Not much is known as of late. What is currently known, for currently unknown reasons, is that Dark Heart harbors a deep hatred against Heart, due to the latter would possibly bring about a tragedy in the future timeline.

Little known about her past history before travel back to the past, as Scharlachrot and Weiss was her sergeant, meaning she was possibly attended Rosenberg from her timeline.
