If you’re wondering how to get Byeken in Anime Vanguards, you’re not alone. Byeken is the newest secret unit introduced in Update 6, and unlike most units, it isn’t acquired through gacha or stage drops. Instead, unlocking Byeken requires completing a multi-step questline that spans across PvE, PvP, and specific event stages.
This guide breaks down every requirement and quest step needed to unlock Byeken, along with tips to optimize your progress and avoid known bugs.
What is Byeken in Anime Vanguards?
Byeken is a secret late-game unit designed for advanced players. It cannot be pulled from banners or obtained through casual farming. Players must follow a specific set of tasks that test mastery across different gameplay modes, including Story Stages, Legend Stages, PvP, and event bosses.
While the process is lengthy, Byeken rewards your effort with powerful capabilities meant for high-level content. Let’s go through each step required to unlock this elusive unit.
How to Unlock Byeken – Full Quest Guide
The quest to unlock Byeken consists of four major steps. You must complete each step in order, and progress is tracked automatically in-game.
Step 1: Complete Shining Castle EX Act 4 and Get Favorite Drink
Start your journey by heading to the Shining Castle Legend Stage.
Play EX Act 4
Upon completion, you have a chance to obtain an item called Favorite Drink
This is the trigger item that begins the secret Byeken quest
Tip: Use strong AoE and CC units to clear EX Act 4 efficiently, as it can be challenging without the right team.
Step 2: Defeat All Bosses in Edge of Heaven
After acquiring the Favorite Drink, your next objective is to defeat every boss located in the Edge of Heaven map.
This includes:
Story Mode Acts 1 through 6
Legend Stage Acts 1 through 3
Nightmare Mode with Champion Modifier is highly recommended. This increases the chances of crossover bosses from other stages appearing, which may be required for full quest progress.
Note: If you’re unsure whether a boss has been “counted,” continue farming all Acts systematically to ensure full completion.
Step 3: Win 10 Ranked PvP Matches (With Bug Option)
Once the PvE portion is done, players must:
Win 10 matches in Ranked PvP
Currently, a known bug allows players to get match credit by:
Joining a Ranked match
Leaving the game right after spawn
Still getting progress toward the 10-match requirement
Use this method only while it remains unpatched. It dramatically speeds up the PvP portion of the quest.
Step 4: Defeat Chaos Reigns (Act 3) 10 Times
The final step is to beat Chaos Reigns Act 3 ten times.
Located in the Heaven or Hell map
Becomes accessible once the earlier steps are complete
Farming this stage may take time due to enemy difficulty
Warning: Some players have reported that the EVO item does not drop correctly, even after meeting the conditions. Keep farming or relogging if this occurs.
Final Reward: Byeken Unlocks Automatically
After all four objectives are completed:
Byeken will automatically appear in your inventory
No need to manually claim or evolve
You’ll be able to deploy this powerful secret unit immediately. However, the quest does not currently offer visible progress tracking, so ensure each part is thoroughly completed before moving to the next.
Farming and Progress Tips
To speed up the Byeken unlock process, here are some useful strategies:
EX Act 4: Run in co-op with friends to minimize failure chance and speed up clearing
Edge of Heaven Bosses: Use Nightmare + Champion Modifier for maximum boss variety
PvP Bug Method: Join, spawn, leave — do this 10 times quickly if the bug is still live
Chaos Reigns Act 3: Use burst-heavy builds or meta PvE teams to grind consistently
Bug Watch: If your EVO item doesn’t appear after 10 Chaos Reigns runs, try relogging or repeating the stage
Final Thoughts
Byeken is not just a strong secret unit—it’s a reward for mastering multiple facets of Anime Vanguards. From defeating bosses across Story and Legend Stages to navigating Ranked PvP and elite events, unlocking Byeken demands versatility and persistence.
Thanks to event-specific bugs and smart farming strategies, the process can be streamlined significantly. However, it remains one of the most intricate unit unlocks in Update 6. If you’re ready to commit, follow this guide closely and claim one of the most exclusive characters in the game.
