Oni Mask Graphic Tee with Katana and Irezumi Clouding

Grinning through chaos — the Slayer’s Grin Oversized Tee fuses myth and menace in a bold Irezumi-inspired streetwear design. The large back print features a twisted oni mask pierced through the skull by a katana, engulfed in swirling Japanese cloud motifs. It’s a symbol of inner demons, sharpened will, and poetic vengeance — drawn entirely in-house with dark folklore energy.

Crafted from heavyweight 100% organic cotton (200gsm), the tee offers a structured yet breathable oversized silhouette with dropped shoulders and a modern ribbed mock neck. The washed finish gives it a lived-in texture and clean streetwear edge, making it ideal for layering or standing out solo.

The oni mask — a staple of Japanese tattoo culture — represents suppressed rage, protection, or inner torment. Here, its manic grin meets the finality of steel, creating a stark and symbolic graphic that commands attention.

Whether you're drawn to the aesthetics of Japanese tattoo shirts or the deeper meaning behind the art, the Slayer’s Grin delivers both — unapologetically.
