Anime Vanguards just dropped its sixth major update, and with it comes a new secret unit—Byeken. This powerful unit is locked behind a multi-step questline, similar to how players previously unlocked Valentine or used the Red Key in earlier updates. If you’re aiming to unlock Byeken quickly, this guide breaks down each step so you can breeze through the requirements as fast as possible.

Byeken Anime Vanguards – Step by Step Guide!

Step 1: Complete Legend Stage X Act 4

To start the Byeken questline, your first goal is to complete Shining Castle Legend Stage EX Act 4. Once done, you’ll receive an item called the Favorite Drink, which kicks off the full quest chain. This stage is difficult and meant for endgame players. To increase your chances of winning, build a team using:

  • Vanguard Sung Jin Woo Monarch (for Steel Summon)
  • Monarch Aizen (for the double wall ability)

You only need one of each if you’re lacking full Monarch teams. Prioritize units that can nuke or tank efficiently. If you’re still under-leveled, it’s best to focus on easier content and strengthen your roster first.

Step 2: Defeat All Edge of Heaven Bosses

Once you have the Favorite Drink, your next task is to defeat all bosses in the new “Edge of Heaven” map:

  • Story Mode Acts 1 to 6
  • Legend Stages Acts 1 to 3

While you can do this in Easy mode, it’s suggested to run it on Nightmare with Champion Modifier. Why? It increases the chance that bosses from other acts will appear across stages—saving you time. This method is RNG-based, but it could reduce how many runs you need overall.

Pro tip: If you’re short on time, use macros to grind from Acts 1 to 6 in both Story and Legend.

Step 3: Win 10 PvP Ranked Matches (Bugged Shortcut)

This quest step requires you to win 10 PvP matches. While normally a time-consuming task, there’s a known bug right now that works in your favor:

  • Join a PvP match
  • Go through the banning and unit pick phases
  • Once the match starts and the enemy begins to spawn, leave the match

Doing this 10 times will still count toward the quest as completed. Use this exploit quickly, as developers are likely to patch it soon. If you care about ELO or PvP rankings, you may want to skip this shortcut and play the matches normally.

Step 4: Eliminate Chaos (Act 3 Farm)

The next quest asks you to “Eliminate Chaos” ten times. This refers to Shining Castle Legend Stage Act 3, also titled “Chaos Reigns.” Just replay this act 10 times to finish the quest. However, some players are reporting bugs with this step. It may not track progress correctly for everyone. In some cases, players have received the unit but not the EVO item needed to evolve Byeken. If that happens, your best bet is to wait for a bug fix in a future patch.

Get Byeken (Secret Unit)

Once all steps are completed, you’ll receive Byeken, the new secret unit. Keep in mind, due to the bug mentioned earlier, you might get the unit but not the EVO material. Track your inventory and stay updated via the developers’ announcements or Discord channels for any patches.


Unlocking Byeken in Anime Vanguards Update 6 is no walk in the park, especially for newer players. But if you follow this guide and take advantage of the current PvP bug, you can greatly speed up the questline. Make sure to prioritize team coordination in X Act 4, grind efficiently using macros or champion modifiers, and don’t wait too long to finish the PvP step before it gets patched. For now, Byeken stands out as one of the top secret units—so if you’re serious about late-game content, unlocking him is a must.
