Early Pacts: The Fox Devil's Fleeting Favor
Aki's first significant devil contract was with the Fox Devil, a powerful entity that offered a straightforward, yet demanding, exchange. By offering a portion of his skin or hair, Aki could summon a gigantic fox head, capable of delivering devastating bites to his foes. This ability, often accompanied by Aki's iconic "Kon!" gesture, was a cornerstone of his early combat strategy, allowing him to dispatch weaker devils with relative ease.
However, the Fox Devil was fickle. It had a preference for "tastier" devil hunters, often refusing to respond to Aki's summons when more powerful or interesting individuals were nearby. This eventually led to the Fox Devil abandoning Aki entirely, a harsh lesson in the conditional nature of devil contracts.

The Heavy Price: The Curse Devil and Shortened Lifespan

The cost, however, was staggering. Each use of the Curse Devil drastically shortened Aki's lifespan, literally consuming his remaining years.

The Future Devil's cost was perhaps the most psychologically tormenting: it demanded to witness Aki's "worst possible death." This eerie promise hung over Aki's head, a constant reminder of his grim fate, yet he accepted it, showcasing his unwavering commitment to his goals. His ability to see the future made him incredibly dangerous, but also weighed heavily on his mind. Unpack the full implications of this chilling foresight in our article dedicated to .
