This isn't really a game where you have to get all endings, but here's a list for those who want to. 'Love' and 'bad' are self-explanatory, 'single' is more of a neutral ending. I never planned to have a love, single and bad ending for each ghost; I wanted to leave it up to what fit the ghost's personality.

mare

1 love, 1 single, 1 bad

demon

2 love, 1 single, 1 bad

raiju

1 love, 1 single, 1 bad

revenant

2 love, 3 single

thaye

1 love
