Aki's Contract Portfolio

Aki maintains the most complex portfolio: Fox Devil (routine summoning), Curse Devil (emergency guaranteed kill), Future Devil (free combat precognition). This demonstrates strategic diversification: cheap contracts for routine threats, expensive ones for emergencies, opportunistic ones for unique advantages.

Himeno's Ultimate Sacrifice

Himeno offered her entire body to summon the Ghost Devil at full power. The Ghost Devil manifested completely but was consumed by the Snake Devil before acting. This demonstrates both the immense power of total-sacrifice contracts and their tragic inefficiency when countered.

Multi-Devil Risks

Santa Claus's contracts with the Doll Devil and Darkness Devil show the dangers of multi-devil agreements. The Darkness Devil took her body as payment, leaving her conscious but paralyzed in Hell forever. Multiple contracts create dependencies where satisfying one devil may violate another.
