Kaname gifts the rose to Yuki on return from his long holiday. Yuki does not realise the significance until several chapters later. Following her awakening and the return of her memories, she remembers Kaname promising a young Yuki that he would bring back the rose for her to see, as she was locked in the Kuran mansion and therefore was unable to see the field of flowers for herself.
During the 41st Night, when Kaname tries to force a newly awakened Yuki away from the Academy, the emotional response through her new powers causes a crack to appear in the Resin Rose. It is the only significant item that Yuki takes with her on the 47th Night upon leaving Cross Academy with Kaname. A year later, during the 51st Night when she talks to her young vampire self, she reaches out and finds herself grasping the Resin Rose.
