Description
Ohka, whose name is also rendered as Ouka, is a supporting character in the anime and manga.hack//Legend of the Twilight. She is a player of the fictional online game The World, where her avatar, known as the Divine Fist, belongs to the career Werewolf class, a rare and advanced class available to very strong players. In the game she appears as a tall, pale woman in her twenties with silver or gray hair, blue eyes in the anime and golden eyes in the manga, and wolf ears. In real life, she is a studious, unassuming fourteen-year-old student who works part-time as a tutor for Mireille.

Her personality is defined by a love of combat. She is a passionate fighter who constantly seeks a worthy opponent and longs to become stronger. She is confident, direct, and eager for battle, and she favors close-range fighting using her fists and legs rather than weapons. Her playful side emerges in her interactions with Shugo, whom she meets at a special cherry blossom festival together with Rena and Mireille. Shugo is immediately drawn to her, particularly when she takes the form of a white wolf, and Ohka willingly returns his affectionate attention and seems to enjoy the dynamic between them.

In the story, Ohka joins Shugo and Rena's party as a powerful ally. Her combat skill and experience make her an asset during their travels through The World, and she helps the group face the monsters and threats they encounter. When the group is captured by the Cobalt Knights, Ohka, Mireille, and Hotaru are allowed to leave after promising not to interfere, but Ohka chooses to return and help Shugo and the others see their mission through. Her loyalty to her companions ultimately outweighs her instinct to pursue personal challenges.

Ohka's most notable ability is her Werewolf class power, which allows her to shift between her human-like form and a white wolf form that can still speak human languages. She is also an accomplished hand-to-hand fighter, using her fists and legs at a very high level. On one occasion she needed to be changed back from her wolf form through a data drain, showing that her transformation carries some risk.

Her development is seen mainly through the contrast between her fierce in-game persona and her quiet real-life identity, and through her growing attachment to the party. While her core desire for strong opponents remains constant, she becomes a dependable companion who fights not only for personal satisfaction but also for her friends.
