Chitose Kizuki's Landmine works on things she has already touched, which normally means planning ahead. Detnerat's answer was a wristband that unfolds into a weapon around her hand, letting her carry the blast with her and set it off at arm's length.
The Curious Flattener is a Detnerat product issued to Chitose Kizuki, an officer of the Meta Liberation Army. Its debut falls in chapter 226 of the manga and episode 109 of the anime.
At rest it is a wristband, formally the Chain Ring Curious Flattener. Triggered, it reshapes into a boxy casing that encloses the hand of the woman known as Curious. Small protrusions jut from its forward face, and detonating those is what carries Landmine, her Meta Ability, into close quarters instead of relying on prior contact.

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
The Curious Flattener is a support item that Detnerat, a company that arms the Meta Liberation Army, built for Chitose Kizuki, an officer of the group known as Curious.
At rest the Curious Flattener is worn as a wristband, but when triggered it reshapes into a boxy casing around Chitose Kizuki's hand, and detonating the small protrusions on its forward face carries her Landmine Meta Ability into close-range combat.
Chitose Kizuki's Landmine Meta Ability normally works only on things she has already touched, so the Curious Flattener lets her carry the blast with her and set it off directly through her hand instead of relying on prior contact.
Detnerat developed the Curious Flattener specifically for Chitose Kizuki.
The Curious Flattener debuts in chapter 226 of the manga and episode 109 of the anime.
