Tanjiro Sword

Any Demon Slayer fan knows that Tanjiro's sword is one of the coolest weapons in the entire manga (or anime, if that's your media consumption of choice). Its pitch-black color is the rarest color for all Nichirin swords, which hints at the immaculate swordsmanship skills that Tanjiro is destined to develop. Even if you aren't dressing up as Tanjiro for your next costume event, this sword is a must-have and welcome addition for any Demon Slayer collector.
