Diablo recruited his old demon acquaintances (Yellow, Violet, White) and Guest to handle mundane tasks like nation-building. However, the real reason for inviting Guest was a pretext to keep them close.

Intro

To delegate mundane tasks, Diablo traveled to the Demon Realm (the Underworld, a spiritual world) to recruit the three demon girls and Guest to the Jura Tempest Federation.

First, Diablo recruits the Primordial Yellow (Jaune) by pinning her down in a fierce battle and demonstrating the gap in their strength.

Second, the plan to cultivate a vessel for incarnation failed due to a subordinate's blunder. Upon receiving the report, the Primordial Violet (Viola) was harshly scolding her subordinate. Diablo appeared, assessed the situation calmly, and shook her by saying, 'At this rate, the smarter White or Yellow might achieve incarnation before you,' skillfully negotiating her recruitment.

Third, he barged in on the Primordial White (Blanc) without an appointment, lightly brushing aside her subordinates who blocked his path. Afterward, as if nothing had happened, they spoke while enjoying tea, and he skillfully proposed the recruitment.

And finally, Diablo goes to Guest. (You may fight back or follow him obediently.)
