I couldn’t verify any official way to unlock “Purple Punch” in Gakuran from the results I found, and the available Gakuran sources I could access don’t mention that unlock specifically. The most reliable recent Gakuran info I found is general game guidance and code/redeem info, not a Purple Punch unlock path.

What I could confirm

  • The current Gakuran guides focus on combat basics, fighting styles, and general tips rather than a specific “Purple Punch” unlock.
  • Recent code guides mention rerolls and the usual in-game code menu, but not a Purple Punch reward.
  • Community wiki-style pages describe Gakuran broadly, but I did not find a documented Purple Punch unlock requirement there.

Most likely possibilities

  • “Purple Punch” may be a nickname players use for a move, weapon, or effect rather than an official unlock name.
  • It may be tied to a newer update, a limited-time event, or a community rumor that isn’t captured in the public guides I found.
  • It could also be a misunderstanding with another game title, since one result about “purple gun” was from a different Roblox game entirely.

Best next step

  • Check the game’s current in-game menu, official Discord, or the newest community guide posts for update-specific unlock notes.
  • If “Purple Punch” is a move name, search within the latest Gakuran tutorial videos or wiki pages for the exact terminology used by players.

TL;DR: I couldn’t confirm a real unlock method for Purple Punch in Gakuran from accessible sources, so the safest answer is that it’s either undocumented, newly added, or being called by a player nickname rather than an official unlock name.
