Flamemaker Shaker W-Engine in Zenless Zone Zero

Powered by a specially formulated fuel, this modified W-Engine is optimized to push combustion performance to the extreme. The engine operates by injecting fuel from the tank into the reaction chamber, where a high-pressure reaction device converts the fuel into searing flames, leaving behind a scorched aroma. It's rumored Nitro-Fuel can also be used as a power source, as there was a sighting of Burnice pouring one into the tank, and later scraping the remaining liquid back into a bar glass after the battle.

"This is definitely slander from a competitor. The special drinks I serve to my customers are always clean and hygienic! The Nitro-Fuel that drains out from the tank is for my own consumption because the high-pressure concentration gives it a special taste!" — Burnice, in defense of her professional reputation, oblivious to her customers unconsciously taking a step back.
