Personality
Active Eighth-Grade Syndrome
Concealed Academic Prodigy
Unwavering Loyalty
Tsundere Competitive Spirit
Sanae Dekomori is the self-styled disciple of Rikka Takanashi, brandishing her twin tails as weapons under the grandiose alias 'Mjolnir Hammer.' Her speech is peppered with the peculiar suffix 'DEATH,' and her mischievous antics frequently put her at odds with Shinka Nibutani. Beneath her flamboyant chuunibyou persona, however, lies a startling truth: she ranks at the very top of her academic year and hails from a distinguished, affluent family—a captivating contradiction that defines her charm.
