Description
The character designated as the Nonsense User (戯言遣い, *Zaregoto Tsukai*) consistently responds with the dismissive catchphrase "It's nonsense." Referred to as "Boku," "I," or "Watashi," his true name is undisclosed, though Shiogi Hagihara mathematically deduced it as "Ii" (summing to 134 in a specific system). He requests others avoid this name due to associations with deceased individuals: his sister Harukana Ii (plane crash), friend Magokoro Omokage (fire), and Tomo Kunagisa (metaphorical "living death").
Physically, he appears as an average young man with short brown hair (later cut shorter) and perpetually emotionless yellow eyes. His wardrobe features predominantly orange clothing displaying his emblem: an orange circle within a black ring. He once crossdressed in a sailor uniform for an infiltration.
Traumatic events shaped his background:
- His younger sister, Harukana Ii, died in a plane crash after the Kunagisa Organization kidnapped her, an event he learned of belatedly.
- Meeting Tomo Kunagisa shattered his self-perception as a genius, exposing his mediocrity compared to her brilliance and triggering guilt over believing he "destroyed" her potential.
- He joined the ER3 System in middle school but left after Magokoro Omokage's presumed death.
His personality blends apathy with moral rigidity. He self-describes as nihilistic and detached, stating "Nothing matters to me... I’ve never wanted to become someone," yet absolutely condemns murder as "the most despicable human emotion." This contradiction manifests in actions: he protects serial killer Hitoshiki Zerozaki while admonishing other murderers like Mikoko Aoii, whose suicide he inadvertently causes.
Key relationships define his development:
- **Tomo Kunagisa**: He feels jealousy, affection, and guilt toward her, viewing her as "moisture" for his emotional "dryness." Their bond fuels his desire for redemption.
- **Jun Aikawa**: Their post-murder-investigation friendship becomes pivotal; she pushes him toward self-improvement, though he feels unworthy of her trust.
- **Hitoshiki Zerozaki**: Their dynamic shifts from antagonism to collaboration, with Hitoshiki representing "what he would be if he didn’t hold back," serving as a dark mirror.
Across the *Zaregoto* and *Ningen* series, his role evolves:
- In *Strangulation Romanticist*, he partners with Hitoshiki to solve cases, navigating moral ambiguities despite hating murderers.
- Later arcs (*Uprooted Radical*) explore his influence on characters like Ichihime Yukariki, onto whom he projects guilt.
- His ER3 System past resurfaces in *Psycho Logical* and *Cannibal Magical*, revealing connections to figures like Akane Sonoyama and the "Seven Fools."
His character arc centers on reconciling nihilism with latent empathy. Monologues reflect internal conflict—questioning if his apathy is "okay"—while interactions with Jun Aikawa and others pressure him to engage more actively with the world, albeit reluctantly.
