Anime Vanguards Update 4.5 brings a challenging yet rewarding Red Key progression quest. This multi-step process not only tests your resource management skills but also your ability to farm and strategically sacrifice units to evolve Sung Jinwoo. Follow this guide to understand each objective and plan your approach effectively.

All Things You Need to Do to Progress Red Key

1. Defeat the Ant King Boss 50 Times

A cornerstone of the Red Key quest is defeating the Ant King Boss 50 times. During these battles, you’ll encounter the Ant Queen mechanic, which opens all tunnels. Remember to run over any open tunnel to close it—this prevents the Ant King from accumulating additional power. The boss increases his HP based on the number of ants killed along his path, so managing the tunnels is key to keeping the fight manageable.

2. Sacrifice 30 Random Mythic or Above Units

Another critical step is sacrificing 30 random mythic or above units, but note that evolved units do not count. The most efficient way to gather these units is by farming in modes like Infinite or participating in the Winter Event, where exclusive units are more readily available. Focus on accumulating a surplus of these units to meet the sacrifice requirement without hindering your overall progress.

3. Summon SJW Shadows 5000 Times

To further progress, you need to summon SJW Shadows 5000 times. The fastest strategy is to enter a dungeon and use as many “press it” abilities as possible. Consider intentionally losing or going AFK with SJW set to auto ability, which allows you to rack up the required summon count without intense active management.

4. Sacrifice Evolved Igris

Once you’ve evolved Igris, this unit becomes essential for the quest. Sacrifice the evolved Igris as part of the progression steps. This sacrifice is a vital component that works in tandem with the other objectives to unlock the next stage in your Sung Jinwoo evolution.

5. Upgrade with the Elixir of Life and Gold

After completing the required sacrifices and summons, take the Elixir of Life to the Upgrade Area along with Sung Jinwoo. This final step requires an additional 50,000 Gold. The Elixir of Life serves as the catalyst for upgrading your unit, marking the culmination of your efforts in the Red Key questline.


The Red Key progression in Anime Vanguards Update 4.5 is a blend of strategic battles, unit sacrifices, and efficient farming. By defeating the Ant King, sacrificing the necessary units, accumulating SJW Shadows, and using evolved Igris along with the Elixir of Life and Gold, you set the stage for Sung Jinwoo’s evolution. Follow these steps in any order that suits your gameplay style, and you’ll be well on your way to unlocking the powerful upgrades that await. Embrace the challenge, and let your strategic planning lead you to victory.
