Vivian was also at Goose Peak Castle at this time, not out on a mission.
Moreover, she's also part of the Seventh Squad, in the same squad as Duke, likely arranged by Grace.
Vivian directly returned to the second-floor dormitory of the third tower and knocked on Duke's door.
After Duke opened the door, he saw Vivian. Vivian was wearing a white and platinum Wizard's Robe, the emblematic attire of the Thorn Holy Tower.
"Duke!" Vivian looked at Duke, somewhat delighted, still seemingly unable to believe it.
She quickly embraced Duke, and they held each other for a moment, a reunion after a long separation.
Duke held her tightly, feeling the warm, soft body and faint maiden fragrance in his arms.
After a while, Vivian shyly stepped back half a step, her cheeks slightly flushed.
Duke took out the Tear of the Stars from the Space Ring and said, "This is a special gift for you, a Level 2 Witchcraft Artifact. See how you like it."
