Hi! I’m able to confirm that the True End and Good End are indeed reachable. Please follow these sequences and do tell me if you still cannot proceed to the correct ending cutscenes!
Do note that Good End and Normal End start with similar lines but different outcomes.
Encounter A: “It’s alright, you can slow down!”, “Don’t worry about tomorrow”, “Let’s talk about it!”
Encounter B: “I hear you”, “No one’s gonna hurt you here”, “Your actions matter more!”
Encounter C: “Your voice doesn’t help people!”, “It doesn’t matter as long as I can help!”, “You don’t have to put others down!”
Good End Final Boss: “Harmonize with Kagame Kagami’s voice”, “Remember your dream!”, “Let it all out!”
True End Final Boss: “Focus and improvise the lyrics”, “You don’t have to sing alone”, “Take my hand”
