Yukina chooses to stay in the "victory fragment" where Rika and Satoko reconcile. She graduates from St. Lucia and becomes a librarian in Hinamizawa – a deliberate choice to remain close to both friends.

Yukina notices Satoko's obsessive behavior toward Rika. She tries to mediate but is pushed away. In one fragment, she is killed off-screen by Satoko in a paranoid episode (implied, not shown).

Touko is the public-facing president who Yukina admires. Initially, Yukina sees in Touko a fellow actor—someone playing a role.
