Hidenori Tabata attends Sanada North High School as a student in Class 2-A, forming a core trio with Tadakuni and Yoshitake Tanaka. His appearance features brown hair, grey eyes, and large frameless glasses, typically paired with the school uniform: a white collared shirt, striped red-and-blue tie, and dark blue blazer and pants. Despite the glasses, he maintains 2.0 vision without them and sometimes wears multiple pairs simultaneously to confuse Tadakuni.
His personality merges extroversion, creativity, and social anxiety. He constantly devises hare-brained schemes, role-playing scenarios, and improvisational routines to combat mundanity and chase an extraordinary life—a drive rooted in childhood. Bullied near an old shrine, he was rescued by the superhero Rubber Shooter, who gifted him an emergency whistle. Rubber Shooter later intervened unsummoned in another bullying incident, cementing Hidenori’s fascination with heroics and fantastical narratives.
Outwardly self-assured as the trio’s leader, he internally overthinks social interactions, especially with girls. Attention from females like the Literature Girl (Yassan) visibly annoys or unnerves him, though his dramatic lines amuse her. He envies those living "manga-like" lives, lamenting his ordinary adolescence. This frustration fuels attempts to recreate dramatic scenarios, such as scaling a neighbor’s balcony after overhearing a melodramatic exchange.
He crafts recurring role-playing avatars, dragging friends into elaborate simulations:
- Jack: A loud, violent warrior who announces himself emphatically.
- Depp: A loyal but inept fighter.
- Bath-house Owner: A stoic, money-focused figure with a deep voice.
- Hopper: A strategist with an exaggerated accent, frequently paired with "Markovich."
- Radio DJ: A comparatively normal host attempting conversational flow.
These personas ranked separately in popularity polls—Jack (55th), Bath-house Owner (57th), and Depp (73rd).
Athletically gifted, he executes feats like a 5-meter horizontal jump without a run-up or converting falls into one-handed somersaults. Quirks include "zipper magic" (manipulating his pants zipper seemingly without touch) and eccentric declarations, like wanting to "piss in his pants" when asked about birthday plans. He treasures friendship, becoming emotional over support and distressed when excluded. His older brother, Yuusuke, was a former ringleader before college.
His Virgo zodiac sign indicates a birthday between August 23 and September 22, with Episode 8 hinting at August. He placed 6th overall (6,309 votes) in popularity polls, while his childhood self ("Young Hidenori") ranked 79th.
