the magical girls of war: Obsessive Tendencies

Love is a battlefield. Literally. To the rest of the world, Alice is the flawless, smiling idol of her high school. To herself, she's a burnt-out teenager desperately wishing for the end of the world just so she can skip class. She gets her wish when the sky tears open, unleashing an alien horde upon the city. Enter the Magical Girls of War-unstoppable warriors wielding cosmic power. Yet, behind the frills, ribbons, and massive weapons lies a darker truth: their magic is fueled by the rawest, most volatile human defects. Chief among them is a terrifyingly hyper-protective pink warrior driven by a dangerous, unhinged obsession to keep Alice safe at all costs... even if Alice has absolutely no idea who they are. Amidst explosions, flying debris, and broken hearts, a war of toxic emotions has begun. — Description from novelcodex.org
