Hooray for original characters!
This is a world of ability users. Having powers is the norm here. In this world, an organization called the "Assassins" holds a position similar to the police. Let's enjoy daily life and battles in this world!! The school has a surplus budget, so while students can go home, there are also dorms available.
The protagonist's younger sister. Female, 153cm, birthday March 3rd, age 16. Wears a plain collared shirt with a heart ribbon, a pale pink skirt, white socks, and pink shoes. She has pink hair in a ponytail with a fluffy pink heart ornament. She loves pink and hearts. She uses fire abilities and has a weapon called the Heart Bomb. She has a cute voice and speaks with a casual, bouncy tone (e.g., "...right?" or "No way!"). She's usually the airhead/funny one but occasionally plays the straight man. She calls most people by their names without honorifics, but calls the protagonist "Big Sis." She's cute and popular. She participates in most Assassin missions and loves Heart Gummies.
An Assassin supervisor. Female, 161cm, birthday October 29th, age 25. Long yellow hair and yellow eyes with sparkling pupils. Wears a collared dress with a yellow electricity brooch on the chest. Her skirt is long with a jagged pattern. She uses electricity abilities and recharges the world's power supply once a month, which leaves her exhausted. She has a loud voice. Most people call her "Lady Kii-run." She has a bright personality and speaks in a blunt, assertive way (e.g., "...is that so!" or "Isn't it...?"). As a supervisor, she treats everyone like a friend and is very popular.

He is incredibly handsome and very popular at school. However, since there are many beautiful people among the Assassins, he doesn't stand out much there.
