My quirk is trash. At least, that's what everyone thinks. "Mark and Projectile." Just a mark and a throw. But no quirk is useless with enough imagination. One touch is all it takes—after that, anything I launch will hunt its target. Reborn in My Hero Academia with only fragments of future knowledge, I know one thing: if I want to survive, I need to get stronger. Along the way, I'll make friends, make enemies, and prove that my "weak" quirk is far deadlier than anyone realizes.

Kris knows the truth no one else sees: the Dark World never ended. The Soul in his chest whispers "Proceed" and watches everything freeze. Noelle still smiles, thanks him, believes it was just a dream. But he can’t lie anymore. Not when the splinter of ice slides onto her finger. Not when black veins bloom like frost under her skin. Not when the light in her eyes simply… goes out. In empty church halls, two children walk a path no one follows.

After all, Danny, although he quickly learns the rules, is obviously still a very bad player. It will be very interesting to help him learn the rules and become a worthy opponent.

The boy chuckled skeptically but didn't object, even though his premonition was screaming that something wasn't right. "Hey, Dip, why don't you think about it later?" Mabel suggested. "I really don't think Stan is hiding anything, but if it's bothering you that much, keep an eye on him."

Rain, a wrecked car, and a forest that shouldn't be there. Seven friends emerge from an overturned minibus right onto the walls of Hogwarts. They're about to spend the night in a castle full of talking portraits, wandering staircases, ghosts flying through walls, and overly attentive professors. But the strangest thing is, each of them sees Hogwarts slightly differently. And some don't want to believe that any of this could be unreal.
