プリムティーネ

The youngest and most inexperienced of the Ten Great Nobles, she is given her title and the castle which affirms her status by her father, the Demon King Hadasht, prior to his sudden death. When Eleanora declares war and she meets Fabio for the first time, she has hardly any followers as everyone who should have served under her dismissed her chances of victory in the upcoming Succession War and switches allegiance to her older brother. She hires Fabio after a short interview and entrusts him with the position of chief military adviser and strategist. She participates in the Succession War to restore the realm to its former peaceful state under her father's rule and to uncover the truth behind his mysterious death.

 She is born with an immeasurable mana capacity which could be fatal to those around her when she occasionally lost control. Her mother died during childbirth as a result of her huge mana reserves, a fact Primtine has always blamed herself for. The flame tree castle (炎樹城) is linked to her and she is capable of moving it by channelling her mana reserves into it. When the castle is under attack, she is also capable of changing the interior at will in response to the tactical situation. As a side effect, keeping the tree under control drains her mana reserves to the point they are so low that Fabio himself is surprised that his personal reserves were higher than hers when they first meet.

Despite her age and inexperience, she is capable of inspiring her subordinates with eloquent pre-battle speeches and has the capacity to rule the demon realm in a fair and just manner. 

She's addicted to coffee and is very particular with her instructions to Fabio on how to prepare her favourite beverage. Although she does drink other beverages, she clearly suffers from withdrawal symptoms when she's deprived of the drink for long periods.

She ascends to the throne on all four character routes, but in her own route she also marries Fabio and is pregnant with his child. /
