Yui appears in the *Make Up! Sailor Guardians* short film as one of two girls seated in a café, engaged in a spirited analysis of the Sailor Guardians’ distinct traits and perceived shortcomings. Her candid critique of the team’s dynamics—questioning their compatibility and effectiveness—triggers a visibly flustered reaction from Usagi, who overhears the conversation. Available sources outline her role in this scene but do not expand on her personal history, character arc, or involvement in other media beyond this narrative moment.
