Hikigaya and the Witches' Romantic Comedy

Hikigaya Hachiman lives by the motto "Loneliness is freedom." That's how it should be. However, on his first day of high school, this motto is shattered. A gyaru who transferred for him, an incredibly cute pink-haired girl sitting next to him who's always secretly watching him, a perfect superhero with long, straight black hair and an overflowing sense of justice, a childhood friend who always smiles and approaches him in a kimono, and that lone wolf with no boundaries… Hikigaya Hachiman's daily life is completely disrupted. Even more absurdly, all these girls are witches. Crossover Oregairu/Manosoba (Magical Girl Witch Trials) — Description from novelcodex.org
