From there, just work on raising your Shot up to Class 9.0. Raise Demonology to 2.0 through the use of the 1.5 Talk skill (Gift: Jewel), and also by fusing the demons you catch through using this skill.
How to level off a skill -
Since Expertise never lands exactly on 00.00(unless you've completely maxed it), and since you want it to be exactly 00.00 to be able to fit everything you want into the build, you'll have to level it out yourself.
To level out a skill, raise it 1 rank above where you want it to stop (so for Demonology, raise it to 2.1, and stop). Once you've reached that point, purchase 1 Lethe WATER (not Bottle), and use it on that skill. It will erase it back one rank, as well as take off any extra, leaving it exactly at 00.00, evening it out.

If you have any questions about any of this, or with raising any of these Expertises, feel free to ask me, since I'm usually around. ;D Good luck!
