All they have to do is reconcile, which obviously won't happen, so how do they get set free? -ported from ao3

In a world where power defines worth, Izuku Midoriya was destined to be nothing. Quirkless. Weak. Forgotten. But fate is not so kind, and the world's cruelty only sharpened his mind, reforged his will, and set ablaze a fire that would never die. Once, he dreamed of heroism. Now, he redefines it. As Dark Phoenix, he rises-a symbol of the forsaken, a nightmare for the powerful, and the catalyst for a revolution that will tear society apart. His battle is not just against villains but against a system built to erase him. And standing in his way? His own blood. Izumi Yagi, daughter of All Might. The sister who swore they'd rise together. The hero who refuses to let him fall. In the end, it is not just Mind vs Might. It is brother vs sister. Dream vs reality. Revolution vs order. And when the flames die down... There will be no heroes left.

Harry wasn't expecting to have a panic attack from DADA class. He also wasn't expecting to be shown the effect of the Killing Curse up close and personal, not when his own mother's green-tinged scream still rings in his ears every single night. In a burst of panic, The-Boy-Who-Lived runs to the only place - the only person - he feels safe with. His adopted father, his Da, Severus Snape. Who is also the only person he's not allowed to love, not if he wants to keep them both safe in the prologue of this inevitable Second Wizarding War. **Good & Dad!Snape AU - Not Snarry**
