エレオノーラ

The ninth of the realm's Ten Great Nobles, she announces her entry into the war for the throne by firing her great Mana Cannon at Primtine's stronghold along with a formal declaration of war. If she wins the war, she hopes to create a demon realm which would be free of prejudice and give hope to depressed and bullied children.

 The scion of a newly-made family with great wealth, her heterochromia makes her the victim of bullying in her formative years as it was a trait shared by one of the infamous tyrants of the demon realm. The bullying briefly made her a shut-in until she came across the mana cannon and swore she would buy it for herself. As her parents refused to buy it on her behalf, she started the demon realm's first delivery company which eventually became so successful (through hard work and considerable trial and error) she was able to buy the cannon for herself. 

The aforementioned mana cannon is the artifact which affirms her status as one of the Ten Great Nobles in addition to her huge mana capacity. She was nominated for the position by Karkel who realised his master would not pay attention to a minor noble and obstruct the nomination. Looking at the eternal cheerful and optimistic Eleonora helped Karkel forget his plight, so he nominated her since doing so would increase the frequency of their meetings thanks to their respective positions. 

When she is captured after losing the decisive battle with Primtine's forces, Fabio successfully converts her to the cause by offering his own virginity to her and claiming hers in the process. Despite the earlier declaration of war, neither Primtine nor herself bear each other any ill will. She spends her time after enlistment tinkering with the mana cannon, buying products from her delivery company and organising victory parties for the army after decisive battles.

In her ending, she writes an autobiography of her experiences in the Succession War and hopes to use it as an inspiration for bullied children. If Fabio proposes to her, she marries him in her True End. /
