Blade Oni is an Epic Character Accessory in Aniimo, an oni mask described in-game as bold and imposing. It carries a fashion value of 40 and serves as the headpiece for the Razor Edge outfit, which comes in both female and male versions.
Quick answer: Buy the full Razor Edge set from the Shop for 1,280 Lumin Crystals, or pick up Blade Oni on its own in the Character Accessories shop for 20 Fashion Voucher.
How to get Blade Oni
There are two routes to owning the mask. Both put the same Epic item in your wardrobe, so the choice comes down to the currency you have and whether you want the rest of the outfit.
Buy the Razor Edge set with Lumin Crystals
Open the Shop and purchase the Razor Edge set for 1,280 Lumin Crystals. This grants every piece of the outfit at once, including Blade Oni and the Thunderblade accessory. It is the fastest way to get the mask together with the matching top and shoes.
Buy Blade Oni alone with Fashion Voucher
Blade Oni also appears on its own in the Character Accessories shop for 20 Fashion Voucher, with a purchase limit of one. This stock rotates, so the mask is not always listed. If you only want the headpiece and not the full set, watch that shop and grab it when it shows up.
Once bought, Blade Oni sits in your wardrobe under Character Accessories and can be placed on any of its 10 attach points.
What comes in the Razor Edge set
Razor Edge is a four-piece Epic outfit. Blade Oni and Thunderblade are the two accessories shared across both body-type versions, while the top and shoes differ. The female version pairs the mask with Mantis Lady and Mantis Lady Shoes.
