how can i get a diffrent ending? it seems like no matter what i do i a;ways get the "bad ending" where you give up from trying to save hineta
The big answer... is that she should not be captured. you're losing.
ideally you want to start a new game and grind strength like crazy until you've gotten 230 strength points. Level 2 +30 more. Which unlocks the ability to win the fight on the 14th. And if you win you get to see extra scenes, and don't have to have shelled out 500 bux.
200 for day 7, 300 more for day 14. (500 total due on day 14 if you didn't pay day 7.)
You can also rescue Hinata (only works a couple times) you try many times to massage her when she lies on the couch in the evening, and when she agrees you can buy a book on massage and upgrade your massage skills. Which lets you bribe (impress) the Madame in the Daimyo's palace and she will help rescue Hinata.
However. Hinata basically has 3 lives, she loses one life every time she is captured/taken, and another life every time she is held captive for a day. When she runs out, you cannot save her or win. OR if you piss off the madame and she kicks you out... you're softlocked into a bad ending of the game.
