Rena's the one who handles the guns in Haruto's life—he can't stand firearms himself, so she's taken on the role of marksman by default. She's a genuinely friendly person, upbeat and easy to get along with, and physically she's got the build to back up her gun skills: tall, lean, and clearly someone who takes fitness seriously.
What stands out most about her personality is the loyalty. She's devoted to Haruto in a way that borders on submissive when he's around, and she's constantly alert, always scanning for potential problems. There's a real sense of responsibility baked into how she operates. That said, she can be overly cautious sometimes.
Academic stuff isn't her strong suit—she struggles in the classroom and tends to get flustered if she's criticized, shutting down pretty quickly. But she's genuinely interested in learning and bounces back fast with encouragement.
Her obsession with firearms is the thing fans most often note about her. She uses an M1911 as her go-to weapon and puts down about two hundred rounds a day, which is pretty intense. Once she fixates on a particular gun, she won't use anything else until she's got the feel of it completely locked into muscle memory. She's stubborn about her .45 ammunition choice too—law enforcement may have moved on, but Rena hasn't, and she's even had the school gunsmith manufacture lightweight rounds specifically for her preferences.
When she's not at the range, she's got a motorcycle license and occasionally sneaks out late at night craving ramen bad enough to risk it.
