Description
Manami Kinjou is a 16-year-old Japanese human female with a fair complexion, brown hair, brown eyes, and a height of 159 cm. She resides next door to Kio Kakazu and has been his childhood friend since early youth. Her family sustains a multigenerational CIA connection via her paternal grandfather, who supplied weapons to the U.S. Army during the Vietnam War; this legacy now exclusively involves her immediate family.

Manami displays a tomboyish, intense, and emotionally expressive demeanor, frequently reacting with loud or violent outbursts—especially toward Kio when he encounters her in embarrassing scenarios. She obsesses over firearms and military gear, earning the moniker "gun otaku" from Kio. Her bedroom doubles as an armory stocked with listening devices and weapons, though many items are later revealed as airsoft replicas. This passion leads her to join a CIA recruitment program supervised by an agent codenamed JACK.

She cherishes a childhood wristwatch gifted by Kio, scratched on the day she realized her romantic feelings for him. She habitually rubs the scratch when anxious. Convinced Kio views her only as "one of the guys," she suppresses her emotions and actively encourages the timid Aoi Futaba to pursue him, fearing his loss to Eris—a Catian alien—and believing she missed her chance.

Manami’s CIA involvement places her in direct conflict after Eris arrives on Earth. She participates in Eris’s capture during an early mission, but Kio identifies her by the scratched watch, causing profound guilt. She later disobeys orders to help Kio free Eris from military custody, resulting in her CIA candidacy termination and severed ties with JACK.

Relocating to the Catian Embassy under diplomatic immunity, she works as a bodyguard. Proximity to Kio intensifies her struggle to hide her feelings. She continues advocating for Aoi’s romance with Kio while visibly seething with jealousy during his interactions with Eris, often destroying objects or lashing out at him.

Her character evolves when Eris explains Catian polyamorous customs permitting multiple partners. Manami reconciles her suppressed feelings and, in the series finale, shares a mutual kiss with Kio alongside Eris and Aoi, embracing their collective romantic relationship under the Catian Embassy’s cultural framework.
