Murasame is a living sword spirit with an unusual reputation—legend has it that anyone who possesses the blade is cursed to meet a tragic fate. Despite this grim legacy, the spirit itself is surprisingly quirky. It can shapeshift into a crow and understands human language, making it far more than just a weapon.
The sword has a habit of perching on Shino's arm, where it entertains itself by pecking at food scraps and dropped morsels. Shino's given it plenty of grief for this nasty habit. That said, Murasame's power is genuinely formidable—it supposedly has dominion over just about anything, regardless of form, making it one of the more dangerous artifacts around.
