Barbatos Bachiko stands as a prominent demon of the Barbatos Clan, famed for their archery mastery and honored as one of the Three Heroes of the Great Demon Valley. She acts as a special lecturer at Babyls Demon School and occupies the role of second-in-command within her clan, serving directly beneath her grandfather, the clan leader. Her lineage ties her to Bars Robin, a younger cousin from a Barbatos branch family. Bachiko presents a distinctive figure: petite at 120 cm tall, with long magenta hair typically arranged in twin tails. Her signature "jail bar" teeth are a notable feature, and she is seldom seen without a Pocky stick or similar treat in her mouth. Her usual outfit consists of a short-sleeved frilled dress, striped stockings, and bow-tied shoes, swapped for tracksuits during training. Initially projecting a brash and temperamental demeanor, Bachiko often comes across as delinquent-like due to her loudness, selfishness, and tomboyish behavior. This attitude springs from deep frustration and disillusionment born of repeated failures as a mentor. Countless demons sought her guidance to learn archery, only to abandon their training, lacking the necessary discipline and patience. This history fostered a cynical outlook, leading her to initially treat new students with dismissiveness. Her formidable abilities revolve around archery. Her bloodline magic, "Full Marks: Hundred Shots, Hundred Hits," allows her to manifest a bow and unleash up to 100 magical arrows simultaneously, guaranteeing unerring accuracy regardless of distance or obstacles. This skill is exceptionally rare, mastered flawlessly by only three individuals in the Barbatos family. She also utilizes the spell "Quartz Quartz" to transform core materials like wood or iron into functional bows. Her prowess earned her the epithet "Undead Archer of Despair." Bachiko's relationships unveil deeper facets: - **Iruma Suzuki**: She initially treats him as an errand-runner, assigning menial tasks instead of instruction. His unwavering dedication and refusal to quit despite her harsh methods gradually earn her genuine respect. Learning Iruma is human—a revelation from Sullivan—solidifies her commitment, recognizing his unique perseverance as key to his suitability as her apprentice. She later gifts him a feather earring commemorating his rank advancement. - **Lord Sullivan**: She holds immense reverence for him, often becoming visibly flustered and shy in his presence. His request to train Iruma compels her to take the task seriously, and she treasures a brooch he gifted her. - **Paimon**: They share a contentious, rivalry-like dynamic, frequently clashing during interactions, though without genuine malice. - **Barbatos President (her grandfather)**: He demonstrates fierce protectiveness, notably threatening the Thirteen Crowns and the Three Greats when they involve her in Demon King succession plans. He later steps down as clan head, appointing Bachiko as his successor and expressing pride in her resolve. Key events shape her development: - **Harvest Festival Arc**: Tasked by Sullivan with training Iruma, she initially neglects her duties until his persistence reignites her teaching passion. Witnessing his growth during the festival cements her pride in him as her apprentice. - **Thirteen Crowns Nomination**: Nominated for a vacancy among the Thirteen Crowns, Bachiko grapples with self-doubt and retreats. Iruma's encouragement helps her overcome insecurities, leading her to accept the position as the "Supreme Archer." Her grandfather formalizes this by transferring clan leadership to her. - **Post-Deviculum**: As a new Crown member, she participates in school events like the Battler Party, supporting Iruma's rank advancement and demonstrating a more engaged, though still easily irritated, mentorship style. Trivia notes include her name potentially being a pun on "Bachi kon," the sound of an arrow striking a target. She harbors a strong affinity for sweets and maintains a complex yet ultimately respectful bond with her cousin Robin, acknowledging his natural archery talent despite his branch family status.
