Re: SACRED EYES
There is no happy ending no matter which path you choose. She either sacrifice her life to perform a "miracle" and defeat the demon that the cultists summon, while the evil priest use it to fuel his ambition to become pope, or she joins the cultist to stop the corruption of the church. However, those cultists are quite fond of sacrificing people to summon their demon lords so its not exactly a "good" ending either. Kinda realistic I guess.
Getting the "Holy Sword" is entirely base on your faith value, you need a value of 100. To my knowledge, the sword does not affect the story in any way. Unless someone figures otherwise, in order to get 100 faith you HAVE to complete the 3rd market scene, which gives up her virginity. This mean that you lose the "Chasity Ring" and the ring is infinitely more useful than the sword.
There are 4 arrest scenes. Its up to chance, save before stealing something and if you don't get caught try again. Do not be arrested more than once per mission, as you can not take the lewd option more than once per mission.
As for virginity, have you bought the bikini at the armor shop? It's the only armor that is buyable. This item usually opens up a lot of stuff. The maid outfit is also used for certain events, such as the two sailors in the slums, and the pub.
I still can't figure out how to get arrested more than twice. There are only two shops where you can steal and she can only get arrested once in each shop. She can steal a helmet from one of the houses but it doesn't seem like she can get arrested there. Also, you CAN get two arrested H-scenes in one mission; with each consecutive arrest, you need a higher "sin" value for the guard to accept.
I know how to get her to work the brothel, the issue is getting her penetrated while she's still a virgin. This requires a lewdness of 100, which seems impossible even with the arrest scenes. The same thing applies to the 3rd market scene. With a requirement of 150, having her be a virgin during the scene that requires her in the nude is even more impossible. Unless there's a way to grind lewdness, I guess those virgin scenes are only viewable in the bonus chapter.
