Rin’s costume is derived from C62 circle cut design of the Team Shanghai Alice poster girl—a character who holds an erhu—thus, the appearance of this rune imitates the musical notes.
Rin is designed as a character outside the scope of normal and Tainted Characters (The description "Between the Two Sides" that displays when this rune is inserted into the Rune Sword also hints at this fact), she have no so-called Tainted variant and never will—which means there is no corresponding “Soul Stone” for
Rin (as in the original game, a “Soul Stone” is a rune that requires the corresponding Tainted Character to unlock). In form, this rune can be regarded as “Soul of Rin” or a substitute item with the same function as a “Soul Stone”.
