Update 21 Units: Prep Guide

Update 21 is finally bringing nine new Anime Adventures Units into the game, and that makes this the best time to clean up your account. After a long content gap, limited events, raid rewards, and competitive resets matter as much as summon luck. If you are stockpiling for the next banner, this guide turns the revealed Anime Adventures Units and outgoing content into a practical checklist.

What Update 21 Changes for Your Unit Roster

The announced lineup is a mix of crossover favorites and names that will have players rethinking their saved gems. The reveal gives you enough time to prepare, but it does not confirm exactly how every unit will be obtained. Treat banner assumptions as speculation and focus on the resources you can bank right now.

That table is intentionally light on mechanics because the announcement is a name reveal, not a full kit breakdown. What you can control is your stockpile: gems, Star Fruits, Star Remnants, Mythic fodder, and limited-event units that may disappear when the update lands.

The biggest mistake is treating Update 21 like a simple summon session. New Anime Adventures Units often compete with evolutions, limit breaks, and trading decisions. If you spend everything on day one without preparing fodder and evolution items, you may pull a strong unit and still fail to use it well.

Priority Checklist Before the Update

Use this order if your playtime is limited. The goal is to capture limited value first, then build resources for the new roster.

Equip full limited-event sets while you farm. April Fools units can provide a 100% currency drop rate when equipped together, and the Sakamoto Days set can provide a 100% drop rate for contracts. That is free efficiency, and it costs you nothing but a team slot.

Do not forget the trading angle. Shiny limited units can become trade pieces, but value depends on demand and scarcity. Keep your only copy of a key support unit unless you have a clear replacement. A shiny flex is nice; losing your best farming unit is not.

Best April Fools and Sakamoto Days Units Not to Skip

These two limited groups are the most urgent because they are leaving. If you only chase a few Anime Adventures Units from each event, start with the standouts below.

Chee Nee is the easiest recommendation for most accounts. Her marking effect raises magic damage taken by marked enemies, scaling up to 150%, and marked targets take an extra tick equal to 7% of her damage every 0.5 seconds. She also hits air as soon as she is placed, which makes her useful in stages where early air leaks punish slow setups.

Valentine is a different kind of investment. Her resurrection passive can bring back the last enemy she damaged every five attacks, at 25% of original health, with a global limit of 10 resurrected enemies. That effect is why she shows up in long modes and competitive content. If you already own her, keep her. If you do not, decide before the event rotates out.

Avenger Full Swordsman Sky Raven is the flashy secret-unit chase. Its attacks add magic damage alongside physical hits, and its White Flash Draw technique gives the first hit a 100% critical chance plus 60% penetration against physical and magic resistance. The cosmetic value is real, but the mechanic is what makes this unit worth remembering.

The Sakamoto Days group is just as important for players who care about limited Anime Adventures Units. Sakamoto is the headline pick because his Slim Down passive stacks damage as he attacks, then adds another 100% boost when the first stage reaches 100%. That totals a 200% damage boost, though he stays a ground unit at later upgrades, so pair him with hybrid units.

Somber Buzzsaw is the bleed answer when regeneration gets annoying. Kill Streak is a low-cost physical storm unit that reaches hybrid form without draining your entire economy. Nagumo gives himself 50% physical crit damage and applies dismembered so enemies take more physical damage, which makes him a strong partner for other physical attackers.

Gem, Star Fruit, and Limit Break Planning

New units are only half the battle. The other half is having enough resources to evolve, upgrade, and slot them into a team.

Build a gem cushion by clearing the Infinite Quest and event quest loop before spending on banners. Event quests can add 500 gems and 35 Sacred Treasure, and the Sacred Treasure exchange can provide 15 Star Remnants daily. That daily habit is small on its own, but it adds up quickly when a new banner arrives.

Infinity Castle is the biggest single gem source on this list. Reaching room 100 awards 15,000 gems, and the mode also feeds Battle Pass progress. Higher ranks can award the shiny Infinity Castle unit, while leaderboard placement can add exclusive units. If a reset is coming, clear as many rooms as you can before it happens.

Limit breaking is the quiet power boost. Each limit break raises a unit's level by 10 and gives the whole team a 5% damage buff. Six limit-broken units equal a 30% team-wide damage increase. The catch is fodder: the process can require sacrificing 12 Mythic units, so budget your duplicate and low-value Mythic units carefully.

Do not limit break random units just to see the number go up. Pick the six units you actually use in your main team. A 30% team buff is worth more than a scattered set of half-built side projects.

Dragon Ball Raid, Trading, and Shiny Flexes

The Dragon Ball raid deserves its own window because it feeds several long-term goals. Kid Buu is a secret ground unit who becomes fully air and hybrid at later upgrades, making him a strong unit to own even if you do not main Dragon Ball teams. The raid also drops evolution items for Goku and Vegeta.

If you own Goku and Vegeta with traits, the fusion system is a major reason to keep farming. Fusing them creates Vegito, and both traits transfer. That gives Vegito the first double-unique setup of its kind. Even if you are not chasing the shiny, the trait transfer alone can justify the raid time.

Trading is where limited Anime Adventures Units become more than collection pieces. Shiny April Fools and Sakamoto Days units can carry real trade value, especially if the events do not return soon. Keep your duplicates organized, avoid trading away your only Chee Nee or Valentine, and decide early which shiny you would actually trade versus which one you want to keep.

FAQ

Which Anime Adventures Units are coming in Update 21? The announced lineup includes Roy Mustang, Rudeus, Thorfinn, Aqua, Darkness, Marco, Enel, Ishmael, and Levi. Obtainability details are not fully confirmed, so save resources rather than assuming every unit is a banner pull.

Which limited units should I get before they leave? Prioritize Chee Nee, Valentine, Avenger Full Swordsman Sky Raven, Sakamoto, Somber Buzzsaw, Kill Streak, and Switch Blade Deception Nagumo. These units cover magic support, resurrection, secret-unit damage, bleed, budget hybrid damage, and physical support.

How should I farm gems fast for new Anime Adventures Units? Run Infinite Quest and event quests daily, then clear Infinity Castle rooms before the reset. Room 100 gives 15,000 gems, which is the largest single payout listed here.

Is limit breaking worth it before Update 21? Yes, if you can commit to your main six units. Each limit break adds a 5% team damage buff, and six completed units reach 30%. Just remember that the fodder cost can reach 12 Mythic units, so do not spread the investment across units you rarely use.
