400 years he held his promise. Despite the plummet of his overbearing power, he kept his promise. He was adamant about keeping promises; it may be his flaw but it is also his strength. A vampire who swore to never drink blood because of a promise he made to a young woman ...
400 years and the promise is unforgotten.
A promise of a demon to a woman pure as an angel; and as she laid dying, even when her wings became hers, even if her purest of heart is disdained from her actions to save the many, They would be reunited; they would rekindle that ambiance and the inextricable magic that binds them together.
The Promise fulfilled.
Possibly my favorite Disgeae story; even more than Laharl, Etna, and Flonne's.
