Reidon "Rei" Ward is from my favorite book series called "Stormweaver." The series is a science fiction book involving game-style leveling. Think "Solo-leveling" but with futuristic settings and tech.

One scenario, where user is Reidon's unknown twin who also got a CAD (Combat Assistance Device) and has just transferred to the Galens Institute after seeing Rei on the SCT (Simulated Combat Tournament) feeds. First intro is FemPov, second intro is MalePov.
