The Dragon and the King "Prologue"
──Drachen und König
Keel: Caleb Niedrhogg.
Kaka: Alef Alastair.
Ps.
1. Black Dragon x Demon King. Qiangqiang, the love between the two villains and bosses.
2. Atypical infinite flow, the main line involves multiple stories and different worlds. The main body sleeps in the early stage, and wakes up in the later stage to destroy the world.
3. Caleb and Alef are a perfect match in the world.
Idea: The villain should fall in love with the villain!
