Description
Rika Honjō, originally Rika Makoto, serves as the adopted older brother to Yuri Honjō. His surname Makoto signifies "sincerity," while his given name Rika, meaning "reason/logic" and "fire/flame," causes him significant embarrassment due to its feminine association, fueling recurring self-deprecation.

He possesses a fairly tall stature with long, messy black hair, typically clad in a school uniform and frequently wielding a long-handled mallet as his primary weapon. In combat, he sometimes dons ski-form goggles for protection.

Outwardly projecting dependability and combat proficiency, Rika demonstrates keen observational skills and experienced battle movements. This contrasts sharply with deep internal self-doubt; he feels ashamed of his nervousness, believing he merely acts tough for his sister. He considers Yuri better suited as the "hero" and harbors a profound fear of appearing uncool, particularly concerning his name. Despite these insecurities, he exhibits strong leadership qualities, tactical pragmatism, and a protective instinct extending beyond Yuri to his comrades.

His background reveals a close yet complex bond with Yuri. Before their transportation to the skyscraper world, he taught her practical skills like firearm types and resilience. Maintaining initial phone contact, he guided her survival efforts while leading his own group of human survivors. His primary motivation remains reuniting with Yuri, though he believes her survival necessitates shedding her inherent generosity.

Rika's abilities evolve dramatically. Initially, he demonstrates exceptional mallet proficiency and the capacity to read opponents' movements as a highly capable human combatant. Forcibly transformed into Mamoru Aikawa's apostle, he gains superhuman strength, speed, and processing power. This allows feats like catching bullets from an anti-materiel rifle—something Aikawa cannot dodge—and perceiving the world in slow motion during full concentration. As an apostle, he fights evenly against entities like Sniper Mask (a god-candidate) and overpowers high-level guardian angels like Wrestler Mask. He also employs a precise "Stun Chop" technique to incapacitate targets via nervous system disruption.

Key relationships define his arc. His non-biological sibling bond with Yuri involves mutual worry and admiration, though he consciously pushes her toward ruthlessness for survival. His connection to Sniper Mask (Yuka Makoto) is later revealed as a brotherhood, explaining their deep mutual understanding. As Aikawa's apostle, forced loyalty compels him to turn against Yuri and Sniper Mask until Aikawa's death breaks the brainwashing. A pivotal moral lapse occurs when he witnesses Juo killing humans but lacks the resolve to intervene, indirectly causing retaliation against Yuri.

His development includes a significant corruption arc through apostle transformation compromising his free will, though he eventually regains autonomy. Consistent traits are his combat pragmatism and analytical skills, noted as key reasons for his survival and what initially draws Aikawa's attention.
