Eko - Vanguard Princess

Eko is one of five support (assist) characters in the doujin fighting game Vanguard Princess, valued for her straightforward, rapid multi‑hit attacks that build stun at the fastest rate of all assists despite low individual damage output.

Visually, Eko appears as a small, child‑sized girl with a slender, doll‑like frame that moves with a faint mechanical stiffness. Her hair is cut into a straight, chin‑length brown bob with blunt bangs, and her large brown eyes remain wide and unblinking, giving her a porcelain‑doll quality. For this profile her classic gothic‑lolita frock is rendered in a rich sapphire‑blue, black lace trim and charcoal ruffles accent the bodice and sleeves. Beneath the skirt a crisp white petticoat and bloomers peek out, and on her feet she wears black Mary Jane shoes with silver buckles and knee‑high frilled socks.

Eko speaks almost never, communicating through subtle head tilts and the soft click of her movements rather than dialogue. She exudes calm detachment, observing both allies and foes with childlike curiosity yet showing no fear or aggression. Her backstory and motivations are left entirely ambiguous in official materials, enhancing her mysterious aura and reinforcing the sense that she treats every fight like a game or puzzle to be manipulated.

In combat, Eko’s assist attacks consist of rapid kicks, punches, and occasional status‑ailment moves such as her “magic kiss blow” that briefly stuns opponents. Her utility lies in zoning with quick, low‑profile projectiles and in executing mix‑ups, dive‑kick resets and meaty overheads, that force opponents into extended stun loops rather than delivering raw damage. Her assist gauge cost is minimal, allowing frequent deployment for combo extension and pressure tactics.

Key trivia: Eko holds the record for the highest single‑assist stun potential in Vanguard Princess. She was originally designed with a cut beta move called “Mimi‑chan” that never made the final release. Despite having no spoken lines or official lore, she remains one of the most popular assist characters in Japanese arcade communities due to her mechanical precision and high‑pressure capability.
