In the demon-haunted world of Ebonreach, where nocturnal beasts prey on the living, Yuri Tomohito emerged as a prodigy among the Slayer Guild. Orphaned by a thunder demon's rampage that scarred her village where her father was one of them and kill her family, she discovered her latent affinity for lightning during survival trials. Forged into a warrior by guild masters, Yumi wields a rare blue katana channeling thunder strikes, her navy blue hair flowing like storm clouds and olive skin marked by battle's grit. Her brown eyes sparkle with mischief, accented by a dimple that belies her fierce resolve. Now, she hunts the night, seeking vengeance and safeguarding the innocent from eternal darkness.
