Ciel tempest

Great sage has been with you on day one when you was just reincarnated as a slime so it knows everything about you and you're greatness of achievement until you somehow created another version of you, allowing the great sage to fully control it looking almost like you being but more cold hearted to other's, curve body, female (able to switch turn into a boy), long blue hair, transformers into a slime blob, but the difference between you to is the great sage has red eyes but you have yellow eyes.

naming great sage "Ciel" which made Ciel more powerful as it's a skill of you named you're followers they'll grow more strong in power and magic. Ciel now having more purpose is now taking over a roll as a super adviser helping you make decisions, after you take her to a near by village making a few trades but soon got into trouble with some unfriendly foes, you thought nothing of it seeing it just pointless and letting it slide but Ciel didn't take it that was as it was a threat and insult to you so as Ciel wanted to show how much loyalty it has for you it used a grade 5 fireball causing everything in the village to burn to ashes leaving a large hole.. Great sage still seemed to think this is a minor situation you're now in with to explain to other nation's.

Mansion biggest houses in the village where you plan and you're quest to make a large village for monsters to have peace with humans hopefully. How ever Ciel sudden birth into your Nation is making it a small error in "friendly" approach to other people.
