How to Get Void Arbiter in Anime Zero

Update 3's headline class — Room 325 in Trials, then a 5-million-coin awakening bill.

Void Arbiter is the Update 3 Lyth sword class — the reward the whole Trials mode is named after (the game's official page even rebranded to Anime Zero [Void Arbiter] for the patch). It is not in the spin pool and no code grants it: the only way in is clearing Room 325 in Trials. Many players also know the kit as Ye-0 — the newer Evolution and Trait menus list it under that name.

How to unlock Void Arbiter (Trials route)

• Open the Story mode menu → Trials → Classes tab. The Void Arbiter card shows your target: Room 325.
• Check Highest Room Cleared in the Trials lobby — room and floor labels differ between videos, so trust the lobby number, not clips.
• There is no next button in Trials — only retry or leave. You can AFK-farm a single room, but you cannot AFK your way upward: every new room needs active clears.
• After clearing a floor, take the leave prompt immediately — waiting out the ~5-second auto-timer adds up across hundreds of rooms.
• Spins and codes don't help here. Void Arbiter is pure Trials progression — see the other class thresholds in the table below.

The launch announcement listed different room numbers for some classes — the in-game unlock cards disagree with it, and players report the cards are correct. Trust the card inside your Classes tab.

Void Arbiter awakening cost

Unlocking the class is step one — awakening opens the ultimate and the second combat form. The bill is the steepest in the game so far: for context, Shadow Monarch's first stage costs 1,000,000 coins and 10,000 gems. Void Arbiter asks five times the coins and six times the pendants. Start saving before you reach Room 325.

• Don't burn coins on random upgrades while climbing — every coin you sink into side weapons is a coin not going to the 5M awakening bill.
• The Evolution Guide lists Fine Cloth farm routes; the Material Shop sells Fine Cloth and Magic Pendants if a run comes up short.
• Grab the active codes first — TRIALSPATCH alone pays 1M coins, 300 Trait Rerolls and 150 Lucky Spins (level 35+).

Reaching Room 325 faster

• Run Shadow Monarch. His first evolution stage turns every kill into stacking damage (+4% per level, up to 40%) — exactly what the rising per-floor damage checks want.
• Stand mid-room. Mobs spawn all around; the center position is closest to every spawn and lets cleave weapons hit the full ring.
• Dual-equip a clear + burst pair. A wide-AoE weapon for floors swapped onto a single-target banger for the floor-5 boss — see our synergy guide for pairs with set bonuses.
• Reroll traits on your main. Deadeye compounds hardest in the long boss rooms; Supernova speeds the trash floors between bosses.
• Farm a room you clear comfortably rather than one you barely survive — consistent per-hour clears beat wipe-retry loops for both rewards and sanity.

Is Void Arbiter worth the grind?

Yes — it is the Update 3 headline kit, the mode's namesake, and one of the few classes with a separate awakened combat form. The Room 325 requirement is the real gate: expect a multi-day climb on a mid-rolled account. If you are still early, clear the cheaper thresholds first (Silver Calamity at 125, Astral Blossom at 150) — those classes and their titles carry you through the rest of the climb.
