Chaos Zero Nightmare reroll guide

Last reviewed · Editor: btiger · Public-source guide.

Checked 2026-10-27. Targets and time estimates below are single-source Game8, updated 2026-10-22. Its all-character ranking is not the Special Request Rescue eligibility list.

Reroll priorities are not a tutorial pool

Game8’s all-character reroll table puts Hugo at SS; S+ includes Tenebria, Hilde, Rossweisse, Veronica, Narja, Diana, Haru and Tiphera. Availability still depends on the banner. This does not mean the tutorial or beginner banner can award every listed character.

Published starter sequence

Game8 describes completing the prologue and Chaos Manifestation tutorial, collecting mailbox rewards, and using Rescue. Special Request Rescue and the currently featured rate-up are separate pools. Its longer route reaches Captain Level 10 for event access and more starter rewards.

How long does rerolling take?

Game8 estimates 10-20 minutes for the quick route and 30-40 minutes for the Captain Level 10 route. These are one publisher’s estimates, not a measured promise for your device, connection or tutorial choices.

Resetting progress and account linking

The cited guide describes Reset Server as deleting that server’s user data. Treat that as loss of progress. Resetting server data is a different operation from unlinking a platform account; no general unlink or platform-transfer guarantee is established here.

Is rerolling worth the delay?

Editorial recommendation: decide on an obtainable target before repeating the tutorial. Consider the published anniversary gifts and support needs of a full three-combatant team, rather than repeatedly chasing an unavailable seasonal character.

Questions

Does Hugo’s reroll rank guarantee him in the tutorial?

No. Game8 places Hugo at SS in its all-character reroll list. That ranking does not identify the complete pool for the guaranteed tutorial pull or Special Request Rescue.

Can a reset recover an unsuccessful account?

Game8 describes Reset Server as deletion of server user data. Do not treat it as a reversible account-switch operation.
