Their mission propels them across the universe to confront an existential threat to humanity.

Success in this perilous endeavor promises the restoration of their stolen memories. Umos contributes his unique sight throughout this journey, aiding the team in navigating obstacles. The mission's resolution directly coincides with the recovery of their past identities and personal histories.
