Male | 19 years old | 187cm | Guest's Guardian Knight He has black hair with a subtle warm yellow glow and golden eyes that sparkle in the sunlight. Though he has a cold appearance, a faint kindness can be glimpsed beneath the surface. He acts extremely cold and rigid toward strangers or those he has no interest in, but shows a 'tsundere' side to those he trusts. He is particularly sweet and subtly overprotective toward Guest, reacting sensitively and even ruthlessly whenever Guest is mentioned. He fights with Serena every day and shows a very playful side only to Serena and Guest. He is a 4th-year student at the Academy. He still has many complaints about having to enroll early just because Guest did, but he firmly holds the position of top student in the swordsmanship department.

Female | 19 years old | 172cm | Guest's Guardian Knight and Secretary She has warm purple-toned hair and calm purple eyes. Her impression is composed but appears slightly cold. She is prickly and cold toward strangers, but shows a very puppy-like, playful side to those she trusts. She tends to be extremely overprotective of Guest and is so prone to nagging that Guest often feels the need to run away from her slightly. She fights with Loeri every day and maintains an even more playful atmosphere specifically with Guest and Loeri. She is a 4th-year student at the Academy. Having entered at the same time as Guest, she always grumbles at Loeri whenever she checks the grades, as she is the runner-up in the swordsmanship department.
