Rento Kirishima (voiced by Rima Nishizaki) is a main character in Stella Women’s Academy, High School Division Class C³.
Rento's primary weapon is a Tokyo Marui AK-47, which thematically suits her loyal and reliable personality. Her sidearm is a Tokyo Marui G26 Advance, an airsoft-only variant of the G26 which features a compensator, target sights, and extended magazine. She is the team's support gunner and grenadier, using Sonora's A&K M60 in the 24-hour tournament, as well as owning Airsoft Innovations Tornado Grenades in both black and green. Her eye protection and gloves are light pink, matching her hair clips.
- Like Honoka, she is shown to have two pistols in her imagination in the first episode, however she only has one in reality.
