I can’t verify the exact unlock method from the game itself right now, but the public info I found points to Reze being a selectable/obtainable character in anime-style Roblox games through a specific dungeon, drop, or event-style unlock rather than a general shop purchase. In one recent guide, Reze’s related soul in a similar game drops from a dedicated “chainsaw” dungeon at a 3% rate, then is awakened with materials from bosses.

What to try

  • Check the event, dungeon, or boss area tied to Chainsaw Man content.
  • Look for a Reze banner, soul, or drop in the character unlock menu.
  • If there’s an awakening system, expect to need materials plus a scroll/item after getting the drop.

Why this is likely

A recent showcase/guide for a Reze-related unlock in an anime Roblox game says the character came from a specific dungeon and needed extra items to awaken , which is a common pattern for these games. Separate fan/game pages also describe Reze as a Chainsaw Man hybrid character, which matches why she would be tied to Chainsaw Man content in-game.

Best next step

Open the game’s update notes, Discord, or in-game quest menu and search for “Reze,” “Bomb Girl,” or “Chainsaw.” The wording may differ by game, so the exact unlock could be a drop, quest reward, or limited-time event rather than a direct purchase.
