The Anime Vanguards Update 6.5 is one of the most content-packed updates to date, introducing seven new units through various mechanics—Slime Portal, Spring Banner, and World Lines Event. Each unit comes with its own acquisition method and unique evolution material, making this guide essential for players looking to collect them all before the event ends.
Whether you’re aiming for the powerful Slime King Rimuru, rare banner units like Koguro, or the exclusive Invincible Class unit from World Lines, this breakdown will walk you through everything you need to know.
Slime King (Rimuru) – Portal Unit
How to Get: Slime Portal drop, which has a 0.5% chance to appear from Spring Portal Tier 10 completions.
Drop Mechanic: Once you enter the portal, defeating the boss guarantees a 100% drop of Slime.
Evolution Material: Shamrock – 5% drop rate from any Spring Portal Tier (1–10).
Farming Tips:
Prioritize clearing Spring Portal Tier 10 repeatedly.
Shamrock is the bottleneck for evolution, so farm early and often.
Despite the portal’s low appearance rate, the Slime King itself is currently one of the easier secret units to evolve.
Koguro – Spring Banner (Secret Unit)
How to Get: Spring Summon Banner (limited-time availability).
Drop Mechanic: Standard gacha roll.
Notes: Koguro is one of the rarest and most difficult units to obtain in Update 6.5.
Tips:
Save and use Flower currency or tickets specifically on the Spring Banner.
Consider activating selection perks (if available) to increase odds of pulling Koguro.
Rudy (Rudeus)
How to Get: Spring Summon Banner.
Evolution Material: Magic Dome, obtainable from the Spring Shop.
Notes:
A strong all-around unit; make sure to secure Magic Dome early to avoid bottlenecks during evolution.
Hibana (Himeno)
How to Get: Spring Summon Banner.
Evolution Material: Fire Flower, also found in the Spring Shop.
Marlin (Merlin)
How to Get: Spring Summon Banner.
Evolution Materials: Sacred Treasure (Spring Shop) and Shamrock (from Slime Portal).
Ark (Arus)
How to Get: Spring Summon Banner.
Evolution Material: Mystic Glasses, purchasable from the Spring Shop.
World Conqueror vs Invincible – World Lines Exclusive
