Ch. 1Chapter One: Aozaki Touko, the Doll Master / Chapter Two: Where Did Big Sister Go?
Aozaki Touko traveled to Germany to bargain with the Einzbern Family for its Android technology and knowledge of the Third Magic, offering to win the Holy Grail War for them. She demonstrated Suigintou's power, but Hadon questioned whether bringing a puppet showed real sincerity.
- Aozaki Touko abandoned her failed attempt to create a human-compatible doll and went to the Einzbern Castle to obtain the family's accumulated technology.
- Aozaki Touko proposed that the Einzbern Family provide Android technology and information on the Third Magic in exchange for her winning the Holy Grail War and bringing the Third Magic back.
- Hadon challenged Aozaki Touko's confidence, so she unveiled Suigintou and demonstrated her combat ability against the Android army.
- Hadon ordered the Androids to stop attacking, acknowledged Aozaki Touko's talent, and criticized her for bringing a puppet to negotiate.
