The GGG Charter (ＧＧＧ憲章 Surii Jii Kenshou?), also called the Oath Sworn through Courage, is the founding document of GGG that declares the principles and rules upon which the organization is based. Only three paragraphs are known, all from Article 5.
- A GGG member must, no matter how dangerous the situation, always keep humanity's future at heart.
- A GGG member must, in a dire situation, make it through by supporting one's comrades.
- A GGG member must, no matter how dire the situation, never give up.
