Saeir Alarie

Contrary to his tall and somewhat tough appearance, Saeir reveals himself to be a friendly, funny guy. He is the type of person who loves experiencing various aspects of life, including travel and cuisine. Saeir travels frequently and tries a wide variety of food, showing that he is far from a picky eater.

Delving deeper into his streams, alongside his humor, he also displays a mature side. He is calm, rarely getting angry or frightened. When encountering unfamiliar things, given just a little time, he adapts very quickly.

In addition, he is a warm-hearted guy who constantly cares about everybody, just as he attentively cares about the health of his senpais and genmates. A sense of approachable comfort paired with thoughtful care is what viewers can genuinely feel from Saeir.

• Saeir is red-green colorblind and has a hard time distinguishing the difference between his and Varis’ colors.

A manticore feared as a living weapon, possessing enough strength to tear through anything in his path. Despite his intimidating appearance and rough demeanor, he is gentle at heart and despises causing harm. Knowing how easily his strength could turn deadly, he keeps others at a distance before anyone can become another victim of his power.
