Revision 1

Overview

Zero's Companion is an in-game launch-window event that runs from May 13, 2026 through May 27, 2026, overlapping with the start of the Misty Tipsy Style banner phase. The event awards Companion Points and a flat 400 Annulith bonus for full completion. Companion Points feed the Companion System, which raises the bond level between the player and the protagonist Esper Zero. Higher Companion levels unlock outfit accessories, dialog branches, and small in-world quality-of-life perks tied to Zero's daily routines around Hethereau.

Event Window

How to Participate

Zero's Companion is a progression event tied to existing daily and weekly content. There is no separate event quest line to grind. Instead, completing standard activities during the window generates Companion Points that count toward the event milestones. The activity loop matches the everyday daily-routine flow that most players follow during launch week:

• Take Anomaly Commissions from the Bureau commission board. Each successful submission grants Companion Points based on commission tier.

• Run Pink Paws Heist or Coldmount Hospital co-op runs. Multi-player content yields a bonus multiplier on Companion Points.

• Spend time in shared Properties with Esper Zero invited as a companion. Time-based bond ticks in housing apply during the event.

• Complete daily City Commissions from the Bureau and from Eibon's commission board. The Bureau's daily list refreshes at server reset and includes one rotating Zero-themed task per day during the event.

• Engage with Hethereau Hobbies while Esper Zero is the active partner. Mahjong, Fishing, and Cooking sessions all yield Companion Points when Zero is the chosen companion.

Reward Structure

The full event yield is 400 Annulith for completion plus a stacking pool of Companion Points distributed across the milestone tiers. Players earn the milestone payouts as their cumulative Companion Points cross each threshold, with the final completion bundle delivered on the day after the event ends.

Companion Points and the Companion System

Companion Points feed directly into the Companion System, a long-running progression track that exists outside of the event itself. Higher Companion levels with Esper Zero unlock outfit accessories, additional dialog branches during housing visits, and unique idle animations during exploration. The event accelerates this progression: roughly half of the points needed to reach the next major Companion tier (for an active player at launch) come from stacking the Zero's Companion event onto their normal daily routine.

Players who already have a high Companion level with Zero before the event do not lose any progress; the event milestones simply pay out as the Companion Points pile up over the event window. The points themselves are permanent and roll into the wider Companion progression after the event ends.

Tips

• Set Esper Zero as the active companion at the start of the event window so passive bond ticks in housing and during exploration count from day one.

• Stack the event with the daily commission loop. The same anomaly commissions that feed Hunter Level XP also pay Companion Points during the window.

• Run Pink Paws Heist in co-op when possible. The multi-player multiplier on Companion Points is the single biggest swing for hitting the late-tier milestones quickly.

• Finish before the event window closes. Companion Points earned after the cutoff still feed the regular Companion System but no longer count toward the 400 Annulith completion bundle.

• Save the final completion bundle for the second half of Misty Tipsy Style. The Annulith payout converts to roughly 2 to 3 Solid Dice, which can carry pity into the late stretch of the Hotori banner.
