I am utterly obsessed with this game! Yasha is so unhinged and I adore him for it.

Once I realised what was going on, I had to keep playing it over and over again, the subtle differences in the narrative each time I got a new ending was so much fun to see. Also thank you for the guide, ending 3 and 12 kept eluding me (poor Sage suffered a lot q.q).
