I've bought a lot of anime merch that looked better online than in my hands. This is the opposite. The hilt has real weight, the sleeve sits on your back like an actual saya, and when the rain starts, the whole bus stop watches you unsheathe an umbrella. Peak fiction, real life. Already eyeing a second character.
- Closed length: ~35" (88 cm) — real katana length, hilt included
- Open canopy: ~41" (105 cm) across — full-size coverage for you and a backpack
- Frame: 16-rib build for a wide, sturdy canopy
- Carry two ways: slung on your back in the included sleeve with adjustable shoulder strap, or in hand like a cane
That closed katana length is the whole illusion — from behind, it reads as a real blade on your back.
- Canopy: pongee polyester — water-repellent with a UV coating, so it covers you in rain and sun
- Frame: ~16 fiberglass + metal ribs, wind-resistant, one-press auto-open
- Handle: molded ABS katana hilt (tsuka) with tsuba guard and a fabric-wrapped grip
- Included: saya-style carry sleeve with an adjustable shoulder strap
Care: shake it out and let it air-dry fully open before sliding it back in the sleeve — don't machine wash. That's it.

Drew this off my back outside the theater when it started pouring and the whole line lost it 😭 The Zenitsu canopy is even brighter in person. It THUNDERS and I'm literally the lightning guy. Peak.

Got my boyfriend the Tanjiro one for his birthday and now the man checks the weather app every morning HOPING for rain 💀 It's a legit solid umbrella too, not some flimsy prop. Best gift W in years.

Expected a cheap prop, got a real 16-rib auto-open umbrella with a molded hilt that has actual weight to it. Wore it to the con on the shoulder strap and got stopped for pics all day.

The hilt is the whole point
