Infinity Nikki Sovereign of Sweet Returns is a permanent challenge added with Version 2.11. You unlock it by completing the world quest The Sovereign Descends! Golden Age Style!, then head to Itzaland to face the Sovereign and earn styling rewards.
The banner disappears after Version 2.11, but the Sovereign challenges remain in the game. You can return to Itzaland later rather than rushing through every challenge before the update.
Infinity Nikki Sovereign of Sweet Returns: Unlock requirements
Complete the world quest The Sovereign Descends! Golden Age Style! first. Reaching Itzaland or opening the event page alone won’t unlock the challenge.
- Update Infinity Nikki to Version 2.11 or later.
- Progress in Itzaland until you can undertake the world quest The Sovereign Descends! Golden Age Style!.
- Complete that quest to unlock the Sovereign challenge.
- Travel to Itzaland and access The Sovereign of Sweet Returns.
- Complete the available Sovereign challenges for the listed rewards.
Track The Sovereign Descends! Golden Age Style! in your quest journal. After finishing it, return to Itzaland for the challenges. The notice doesn’t identify a quest-giver or map coordinate.
If Infinity Nikki Sovereign of Sweet Returns is still locked, check whether that named world quest is marked complete. Other Sovereign quests and Mira Crown contests don’t count as the prerequisite.
Is Sovereign of Sweet Returns permanent?
Yes. Infold states that the challenge itself is permanent after the Version 2.11 update. Its promotional event page, however, is only displayed during Version 2.11. After that page closes, you can still travel to Itzaland and continue the experience.
The 26 November cutoff applies to the Version 2.11 promotional page, not the permanent challenge. If you’re busy with limited-time events, you can return to the Sovereign afterwards.
Once the world quest is complete, Infinity Nikki Sovereign of Sweet Returns stays available in Itzaland. The disappearance of the event banner doesn’t remove the mode.

All confirmed Sovereign of Sweet rewards
The publisher lists three reward categories: the Sweetheart Stripes Collage Poster, Resonite Crystals and growth materials. These are attached to the Sovereign challenges rather than to a one-time login reward.
| Reward | Source |
|---|---|
| Sweetheart Stripes | Collage Poster from the Sovereign challenges |
| Resonite Crystals | Challenge rewards |
| Growth materials | Challenge rewards |
Check the challenge screen for its styling conditions and score requirement. The Version 2.11 notice confirms the rewards, but doesn’t give a winning outfit or opponent-by-opponent scoring table.
The poster is named Sweetheart Stripes, not a new gacha outfit. Likewise, a Resonite Crystal earned through this challenge is different from a Starlit Crystal used in the 2.11 Starlit Shop.
Is it related to Mira Crown Pinnacle Contests?
No. Infinity Nikki Sovereign of Sweet Returns and the Mira Crown Pinnacle Contests are separate activities. The latter updates its phases during Version 2.11 and has its own scoring modifier.
Mira Crown’s first phase runs from 1 November at 04:00 to 16 November at 03:59 server time. Its second runs from 16 November at 04:00 to 1 December at 03:59 server time. Both have a 15% bonus to glowed-up pieces. Those phase dates do not impose a deadline on the permanent Sovereign challenge.
What if the event banner disappears?
If you’ve already completed the world quest, head back to Itzaland. The publisher explicitly says you can continue the challenges after the Version 2.11 event page closes.
If the world quest isn’t complete yet, track The Sovereign Descends! Golden Age Style! and finish it first. The Infinity Nikki Sovereign of Sweet Returns unlock is tied to that progression, not the visibility of the temporary promotional page.
There’s no 26 November deadline for finishing Infinity Nikki Sovereign of Sweet Returns. The banner is temporary; the challenges and rewards remain.
