Question about the Epic Trial key.

I've been wondering this for awhile...
If I use my epic trial key, then buy some skills, (factions only skills), and after that the trial expires, do I get to keep my skills or do they just vanish?

When you unlock skills for a chapter you don't own, they are locked after the trial expires. You get the skills back when you buy the chapter, but you can't use them until then.

...That really sucks.

However, you do actually get to keep Zenmai if you get her, or Olias, whichever.
