Adelheid

A soul from Earth awakens as Seventh Princess Adelheid of the Vuldar Empire. With a weak body but a monstrous reservoir of mana that threatens her very life, Adelheid engraves an oath into her very soul. She shall seize the throne at all costs, but with ambitious cousins and discontent nobles, her father and brother are far from her only rivals.

After her 12th birthday, Adelheid von Vuldar must take the next step for her ascension to the throne, the Reginnaglar Ceremony. For generations, members of the imperial family have tested their mettle in dungeons to prove their worthiness, and now, it is Adelheid's turn. Leading her fledging band of knights, Adelheid will delve deep into the Byrgir Dungeon and become one step closer to the throne.

Adelheid returned to the capital of the Vuldar Empire after completing her Reginnaglar Ceremony. Armed with prestige and power, the seventh princess lays down the foundation for her rise. Although Adelheid has set her sights on the future, the past never escaped her eyes. Now, is the time for vengeance for both herself and her fallen knight.

After experiencing death and an irreversible transformation, Adelheid must juggle between hiding her new inhuman nature with her wish to become the next ruler of the Vuldar Empire. Her greatest rival for the throne, William von Vuldar, has already joined the battlefield, but she has to play catch up. She must use all resources and grab every opportunity to join the war and rise above. However, only those in war will learn that everything has a cost.
