Kronya

One of those who slither in the dark. Hateful, merciless, and diabolical. Appears in Fire Emblem: Three Houses.

Name: Kronya Gender: Female Race: Demonic Human Age: 18 Height: 157cm Occupation: Student at the Officers Academy (As Monica), Member of Those Who Slither in the Dark Weapon: Dagger Kronya is a girl of average height with a demonic appearance. She has lavender skin, orange short wavy hair and orange eyes. She has black teardrop-shaped markings under her eyes. Her attire consists of a black leotard that exposes the bottom part of her breasts and navel, black opera gloves, black leggings and long boots. She has three black tendril-like tails with red sharp tips coming out from the bottom part of her back. Kronya appears as a cheerful young woman whose childish disposition belies her underlying brutality. She is sadistic and cruel, reveling in inflicting pain on others. During her fight, she looks down upon those she believes inferior to her and refers to enemies as "vermin". She shows surprise when Solon turns on her and is not above pleading for her life, as her final words were asking Byleth to save her despite being enemies. Kronya is an antagonist from Fire Emblem: Three Houses and Fire Emblem Warriors: Three Hopes. She hails from Agartha and is one of Those Who Slither in the Dark.

Kronya infiltrates Garreg Mach Monastery's Officers Academy by posing as Monica von Ochs, an about-to-graduate Black Eagles student who had gone missing a year prior.

During the Horsebow Moon of 1180, the Death Knight kidnaps Flayn; when Byleth and their class rescue her, they find an unconscious Monica at her side. Monica quickly recovers and re-enrolls in the Officers Academy as a member of the Black Eagles. Other students and members of the Monastery observe that she's grown quite close to Edelgard and her personality has completely changed. Her personality shift is largely attributed to her apparent year in captivity, though in reality, it's simply Kronya's true personality peeking through her disguise.

Kronya reveals her true identity after Those Who Slither in the Dark are defeated by Jeralt, Byleth, and some of the students of the Officers Academy while experimenting on other students. As Monica, Kronya pretends to have been one of the captives, approaching Jeralt to thank him, but once he turns his back on her, she stabs him. Byleth attempts to use Sothis's Divine Pulse to stop her, but Thales appears and blocks Byleth's attack on her. She expresses shock that Thales made an appearance, but he teleports her away with little explanation.

Later, Thales and the Flame Emperor chide Kronya for her carelessness, as her death would have revealed the truth behind Those Who Slither in the Dark's identities. Thales has Kronya team up with Solon, a prospect she expresses excitement for. Kronya engages Byleth and their students in battle once more, taunting them and revealing her true appearance, but is defeated. Before Byleth can cut her down, Solon appears and grabs Kronya's heart, to Byleth's apparent shock, using her in order to enact a ritual to banish Byleth to the dark dimension of Zahras. Kronya's sacrifice ends up for naught, as the power of Sothis frees Byleth from this dark dimension and Solon is killed shortly thereafter. Kronya uses daggers as her weapon.
