This review was machine-translated from the Japanese original. Numbers are checked against the original; if the wording reads oddly, the Japanese version is authoritative.

The more you keep shooting, the harder it becomes to stop, Vladof-made “Never runs out of ammo” SMG. Each fired bullet has a 30% chance to not consume ammo and adds extra damage, and the fire rate increases the more you fire. With a COV‑licensed infinite magazine, you can fire continuously while watching the heat, a hand‑count specialized type.

🧩 Origin of the red text Internet meme “Are ya winning, son?” is parodied. The word “winning” (are you winning?) is replaced with “spinning” (are you spinning?) to match the spiral trajectory of this gun’s bullets. The behavior of bullets flying in a spiral path matches the line. (Clear source verification from external primary sources is (unverified). Multiple DBs and NamuWiki note that it is a meme parody.)
