Who to Pick for Each Ending

Target Character Key Chapters for Affinity Critical Choices Notes
Aerith 1, 2, 4, 6 Always choose sincere, emotionally open responses. Validate her Cetra nature. Never deflect her personal questions. Default front-runner. Tiebreaker priority 1. Easiest to achieve high affinity naturally.
Tifa 1, 3, 7 Reference Nibelheim and the water tower promise. Responses about protecting her specifically score highest. Requires consciously directing Cloud's emotional openness toward Tifa across all chapters.
Barret 2, 5, 9 Acknowledge his dedication to Marlene. Respect his sacrifice and mission without being dismissive. Difficult to make him date leader — requires actively ignoring Aerith/Tifa moments throughout.
Red XIII 3, 7, 10 Engage philosophically with his questions. Honor Seto. Never shut down his introspective observations. Very hard to make date leader. Requires treating every Red XIII conversation as a primary priority.
Yuffie 4, 8, 11 Match her energy. Respond to her boldness with humor or respect rather than reprimand. Limited Yuffie-specific choice windows. Hard date target but fun character arc payoff.
Cait Sith 6, 9, 12 Express trust. Don't dismiss him as untrustworthy even when he's evasive. Lowest starting affinity. Essentially impossible to make date leader on a first playthrough focused on other characters.
