Story Overview

Momoka Sendou trains in the Shorinji Kempo tradition and is the top student at her dojo. Her childhood friend Ryuga Kou is a skilled exorcist who summons spiritual power to fight demons. When a summoning goes wrong, the Long, a dragon god, possesses Momoka instead of the intended vessel.

The result: Momoka now has dramatically enhanced physical power when the dragon manifests, and Ryuga has to work with her — his childhood rival — to handle the supernatural threats that keep appearing. Over 8 volumes, the series tracks their partnership, the growing complexity of their feelings, and the escalating supernatural threats.

Characters

Momoka Sendou — A protagonist defined by her fighting ability first and romantic feelings second; her strength is presented as genuinely impressive rather than as a quirky personality trait.

Ryuga Kou — The childhood friend whose exorcism work drives the supernatural plot; his relationship with Momoka has the specific dynamic of two people who have known each other too long to be easily honest about how they feel.

Art Style

Matsumoto draws in the clean, bright Ribon style — expressive faces, dynamic action sequences, and romantic moments that hit the expected visual beats. The dragon-manifestation sequences have appropriate visual weight.

Cultural Context

St. Dragon Girl ran in Ribon from 1999 to 2003, in the same magazine as Sailor Moon and Marmalade Boy. Matsumoto's combination of martial arts action and supernatural romance fit the magazine's tradition of giving its female leads active roles rather than passive waiting. The Chinese cultural elements — Ryuga's exorcism tradition, the Long dragon — were part of a broader early-2000s shojo interest in Chinese fantasy aesthetics.

What I Love About It

Momoka never needs to be rescued. The dragon possession gives her more power than anyone around her, and the series consistently makes her the one who resolves physical threats. The romance develops between two capable people rather than following the standard shojo pattern of a powerful boy protecting a vulnerable girl.

What English-Speaking Fans Say

Western readers describe St. Dragon Girl as light, fun shojo action — specifically noted for Momoka being a more active protagonist than typical for the genre, for the action sequences being genuinely exciting, and for the compact 8-volume format being ideal for readers who want complete romance without long commitment. Recommended for Sailor Moon fans wanting something shorter.

Memorable Scene ⚠️ Spoiler Warning

The sequence where Ryuga's feelings for Momoka become undeniable to him — and specifically the moment he stops treating their relationship as childhood habit and recognizes it as something he has chosen — is the series' most emotionally satisfying beat.
