TO GET LEDAH, This ends right now. Options

[Feral Phoenix]

Get Rose's good ending. I believe that's all it takes. The setup is the same as Chapter 8 with the girls, but you have to bring Lorelei for every battle. Ledah starts out with a 10% HP recovery which increases by 1% every time you move. Ein still can't learn Skills. This version of the chapter has way more plot than the Sprites version and actually has some important information pertaining to Knights. You need to be careful later on and the Hades battle takes way longer. Fight all the battles so you can use every Look trigger. There's quite a lot of scenes that look slashy so that even the fangirls like me don't have to try hard to make it seem like pairing.

Stop guessing and get his version of the chapter now that you know how. You're welcome, everyone.

you should do the work for yourself.

These are video games. They are supposed to be for entertainment or enjoyment, not WORK. He will get nothing more out of it doing the "work" - he won't have developed mentally, emotionally or physically at all from an extra playthrough.
You want to know why people get so angry with you Feral? It's because of shit like this. You expect everyone to be nice to you and do everything for you, yet you say shit like this - he makes a simple request (not even a request, he asked if you were capable of doing it) and you jump on him as if he's your slacker older brother who's always mooching money off of your grandma because she's too kind to realize he's using her.
