The "Bright Moon Special" Arc Research Program launches with the May 13 update and runs until early June. It features the exclusive S-class Arc "Marching Beyond Time", which is currently the only way to obtain this Arc — no alternative acquisition method is planned at this time.

| Guarantee | Pulls Required |
|---|---|
| S-class Arc (any) | Within 6 pulls |
| Featured S-class Arc "Marching Beyond Time" | Within 8 pulls |
All "Limited Issue" pulls share the same Arc pity counter. Pity is permanent and carries over to future "Limited Issue" Arc Research Programs — progress is not lost when this program ends.
What Players Should Know
"Marching Beyond Time" is currently only available through the Bright Moon Special program. The announcement explicitly states no other ways to obtain it are planned, making this the primary window to secure the Arc if it fits your build.
The program uses Tri-Keys, a resource separate from standard pull currency. Check your inventory before the May 13 maintenance ends to confirm your Tri-Key balance.
