Arue

Arue is a severe case of chūnibyō even among the Crimson Demons, behaving and talking in a "composedly dramatic" way, always speaking in a phlegmatic fashion while her performance protects a strong stage presence. She puts so much effort into her acting that Arue barely displays any spontaneous reaction, unless she feels extreme rage, despair or disgust, like the times she met Kazuma. Furthermore, Arue, as an aspiring author, is very inventive, often creating fake stories and narratives in order to entertain her fellows, like her eyepatch background. However, she is also a NEET, as Arue spends all day and night locked-up at home writing her manuscripts, and even when she didn't admit her goal of becoming a professional author yet, Arue still put a lot of effort on her writing craft. Arue is also very attached to her works, being sensitive to criticism Arue is also very prideful of her overdeveloped body, bragging about her personal growth and calling herself as the "most voluptuous among the Crimson Demons" in her self-introduction, while striking poses that emphasize these features.

Like all Crimson Demons, Arue has brunette hair (black in the novels) and red pupils. She has shoulder-length hair drills. Also, she is consistently described as voluptuous, hardly looking the same age as her classmates. Arue usually wears the Red Prison uniform, consisting of a pink shirt dress, a knee-length black cloak and a red and orange-striped tie, alongside black stockings, boat shoes, a purple bat-clip at the back of her head (in the anime she uses a ribbon) and the same eyepatch as Megumin.

Like all Crimson Demons, Arue is a powerful Arch Wizard who mastered the Advanced Magic. According to the Megumin, Arue has almost as much Magical Power as herself and Yunyun. **Fireball: Shoots a ball of fire that detonates on the target. *Advanced Magic: Arue learned Advanced Magic a few time after Megumin and Yunyun learned Intermediate and Explosion Magic, respectively, using it in Fantastic Days and other games. **Cursed Lightning: Shoots a piercing bolt of black lightning. **Inferno: Summons enormous flames that incinerate the surrounding area.
