Gatsu is the Japanese rendering of Guts, the lone swordsman at the centre of Berserk, Kentaro Miura's dark fantasy manga that began in 1989 and was later adapted into several anime series and films. Clips using his Japanese voice performance circulate widely on soundboards and in fan edits, separated from their original scenes and reused as standalone reactions. Because the character is associated with endurance, trauma and explosive anger, the sound has kept its place in anime editing culture long after the broadcasts, especially among Berserk fans sharing dramatic moments.
