Description
Karen Honnouji is a central character in *Duel Masters WIN* and its sequel *Duel Masters WIN: Duel Wars*. She is a kind-hearted and attractive girl who aspires to be an idol despite possessing a severely tone-deaf singing voice often compared to a roaring dragon. Her appearance features green hair, dark grey eyes, and green eyebrows. She typically wears a white hat, a left ear earring, a long yellow dress, a pink purse, a sunflower attached to her wrist, and red high heels.

She meets Win Kirifuda during the Gachidue Battle event and joins his friend group. Later, it is revealed Prince Kaiser coerced her into spying on Win using threats concerning Jashin's corruption. During a duel against Win, she uses a counter-Shinobi deck, but he wins by summoning four Jablood, Wicked Dragons, allowing him to understand her conflicted feelings. Kaiser's associate then discards her as useless by throwing her into a portal. This act, combined with Kaiser's earlier mistreatment of Win's father, fuels Win's rage and motivates his confrontation with Kaiser.

In *Duel Masters WIN: Duel Wars*, Karen initially stays with Win's group but departs in Episode 10 to join the D4 committee, replacing Bowie Obochiyama. She makes this choice to protect the club following Bowie's failure in a trial duel arranged by Kaiser. As a D4 member, she maintains authority; in Episode 36, she confronts Fargo. After he disrespects her, she silences him with a menacing stare and a reminder of his lost D4 position, humiliating him and indirectly causing his destructive outburst against the club. Despite her D4 role, she frequently visits Win's club to socialize.

She is a skilled and respected duelist. She initially uses a Nature Civilization deck focused on the Giant Snow Faerie race. During her duel against Win, she switches to a multi-civilization deck combining Giant Snow Faerie with Shinobi creatures from Light, Water, and Nature civilizations.

Her narrative continues in the manga *Duel Masters LOST*, where she appears as part of Win's group in Shibuya. She engages in duels with Win and others within this amnesia-affected setting.
