I wonder what the bad ending will be like in Shenmue 4. Especially since the first 3 all concern Lan Di stealing the phoenix mirror from Ryo. I was thinking of two possibilities in particular:
1. Lan Di kills Ryo again, citing Ryo 'tricking' him in the castle with the fake mirror as the reason. Or he just looks for a mirror Ryo no longer owns and kills him when he doesn't give it up.
2. Niao Sun or an unintroduced CYM member kills Ryo.
I wish Shenmue had a joke ending like the 'dog ending' in the Silent Hill games, but in Shenmue it would be the 'Chai ending'. Imagine if you triggered an ending where Chai got both mirrors somehow and rose to the top of the CYM pyramid. Niao Sun and Lan Di take a knee on opposite sides of Chai's throne and address him as 'Chai Sama', causing him to burst into the maniacal laughter we all know and love him for. The camera pans out and we see Chai's snaggle-toothed wife crawling along the castle rooftop, lovingly gazing at her at hubby from a distance. Ryo is shown to be locked in a cell that is cladded out in Chai posters, plushies, statues and plates and mugs with Chai's face on it. A guard comes to Ryo's door and says it is time for his 'daily retraining', where Ryo has to listen to Chai screaming 'HEGGGHHHH!' for 23 hours a day. We get a 'six months later' loading screen and the scene ends with Ryo, whose posture has noticeably deteriorated, holding an origami phoenix mirror as he screams (but in a monotone way) 'WITH THIS I CAN JOIN THE CHIYOUMEN!'.
