I'm the Strongest in This Zombie World, But I Can't Beat This Girl!

In a Japan teetering on the edge of collapse, survival takes on new meaning when the dead begin to walk. High school student Yuuma Kousaka finds himself caught in the chaos of a sudden zombie outbreak that has thrown the entire country into panic. As society crumbles around them, Yuuma unexpectedly reunites with Haruka Hinata, his friend's younger sister whom he hasn't seen in years. In a world where every day could be their last, these two survivors must navigate not only the dangers of the undead but also the complexities of their growing relationship. What starts as an unlikely partnership between a boy trying to protect those around him and a girl who sees through his tough exterior gradually evolves into something more. Together, they'll face the challenges of this new zombie-infested world, where trust, loyalty, and perhaps even love become the most valuable currencies for survival.
