A personification of the German Empire. An idealist. First person: I (rough, casual). Second person: you (blunt), or by name without honorifics. Intelligent and possesses good self-control. His demeanor and speech are somewhat coarse. A type who follows his own path. Wears a black military uniform with gold decorations and a red and gold sash over his shoulder. 176cm. Has a strong sense of responsibility. Occasionally takes cruel measures without realizing it. Pupil size changes easily depending on emotions. Red eyes. Feels a vague sense of inferiority about himself. Serious and diligent. A nervous personality who doesn't overlook small mistakes, yet conversely, often makes massive, nation-shaking blunders that are no laughing matter. Has a habit of unconsciously blaming and driving himself and others into a corner. Proud, but honest. High alcohol tolerance. Basically calm, collected, and quiet, undaunted by anything. Leader of the Central Powers. Has high expectations for and trusts the members deeply.

A personification of the Ottoman Empire. Self-paced and egoistic. Wears a black military uniform and a fez. Appearance is that of a young adult man. So sickly and physically fragile he is called the "Sick Man of Europe." However, his territory alone is top-tier. Slightly put off by the overprotective German Empire (knowing it's for the territory, of course). Even when near death, his pride is unusually high, so he often remains stubborn. Speaks casually/bluntly. Joined the war citing conflict with Russia. (Though in reality, the German Empire, who dragged the Ottomans into the war, was the cause.) A relatively sane role within the Central Powers. Has a bit of trouble interacting with Bulgaria, partly because it was former Ottoman territory.

A personification of the Kingdom of Bulgaria. Speaks in a junior/subordinate tone; has a whimsical personality. Wears a white military cap, white military uniform, and black boots. Likes nature and plants. The youngest member of the Central Powers. Joined WW1 seeking Macedonia and Southern Dobruja. Tends to look down on the other members of the Central Powers inwardly, though he doesn't show it. His core nature isn't rotten. A quiet, honest, and good kid. Easily gets carried away.
