OVA
Description
Tohru originates from the dragon realm's Chaos Faction, raised to despise humans as inferior beings. Centuries ago, she battled humans and gods, sustaining a near-fatal injury from a divine sword wielded by a god leading human forces. Retreating to the modern world, she encountered Kobayashi, who drunkenly removed the sword and saved her life. This act sparked Tohru's deep love for Kobayashi, leading her to abandon her destructive purpose and accept an offer to live as Kobayashi's maid.

In dragon form, Tohru appears as a massive green European dragon with black wings and a light green underbelly, towering 15-20 meters tall. Her human form manifests as a 176 cm tall young woman with long blonde hair featuring flaming orange and pinkish-purple tips, red-orange dilated pupils, and a buxom figure. She wears a scale-formed maid outfit modeled after a maid café uniform, keeping her horns visible. She occasionally displays her tail—scaly green atop and smooth white underneath—and wings indoors but conceals them outdoors.

Initially embodying destruction and hatred toward humanity, Tohru transformed into a cheerful, kind maid dedicated to household duties after meeting Kobayashi, though she retains aggression toward perceived threats. She acts as a protective older sister and caregiver to Kanna Kamui. Naive about human customs, she often mimics television or internet content. Her romantic and sexual attraction to Kobayashi drives recurring behaviors, like attempting to feed Kobayashi her regenerating tail meat or covertly using love potions in chocolates, which typically fail.

Tohru wields immense power, claiming capability to instigate Armageddon and ranking among the strongest dragons. Her physical attributes include immense strength, durability, speed, reflexes, and unlimited stamina, enabling cratering impacts and continental-scale travel. Dragon traits encompass fire breath that disperses storm clouds, flight, razor-sharp teeth and claws, cleansing saliva, and a poisonous tail to which she is immune. Magical abilities include shapeshifting, inter-dimensional portal creation, clairvoyance, perception-blocking invisibility, and regeneration.

Her relationships define her development: unwavering romantic devotion to Kobayashi shapes her existence, eventually reciprocated; rivalry with Elma persists despite a truce after Tohru destroyed a temple over Elma's gluttony, leading to Elma's rejected romantic confession; she mentors Kanna Kamui; strained ties with her father Damocles culminate in confrontation over his disdain for her maid life before he relents. She maintains friendships with Lucoa, who checks on her across worlds, and Fafnir, a fellow Chaos dragon she convinces to tolerate humans, while initially clashing with Ilulu before accepting her into the household.

Across media, Tohru adapts to human life while retaining dragon traits, channeling destructive impulses into household duties and protecting her family. She engages in high-stakes battles against threats like her father or rival dragons. Stories highlight her growing understanding of customs like Valentine's Day traditions or hosting guests, evolving into Kobayashi's romantic partner. Her obsessive love and occasional misunderstandings of human norms remain defining flaws.
