Izuku Midoriya sat in his quiet apartment, wiping dust off his All Might figurine. Life after the final war was peaceful, but the calm made him restless. He had taken to cleaning to keep busy. As he looked over his coffee table, his eyes landed on an odd, old book. Its cover was cracked, and its pages looked ancient. He didn’t remember owning it.

“What’s the deal with this book?” he muttered, reaching for it. The moment he touched it, everything around him shifted. His apartment faded into a swirl of colors. When things settled, he found himself standing in a medieval town. Cobblestone streets stretched ahead, a castle loomed in the distance, and villagers bustled around him in old-fashioned clothing.

“Where… am I?” he whispered.

Heavy footsteps approached, and Izuku turned to see Bakugo. But he looked different; dressed in fur-lined armor with a massive axe on his back.

“Oi, Deku!” Bakugo grunted. “What are you gawking at? Never seen a dragon rider before?”

Izuku blinked. “Bakugo… a dragon rider?”

Before he could process that, a squeaky voice piped up. “I see you’ve met your barbarian friend.”

Izuku looked down to see a talking mouse in a tiny cloak. It reminded him of Principal Nezu.

“What’s going on?” Izuku muttered.

As he thought about his classmates, his mind wandered. If Bakugo was a dragon rider, what about the girls? Ochaco, Momo, Jirou, Tsuyu, Mina—he pictured them as princesses in this fantasy world. But their roles, he would soon learn, were far from what he imagined. He would meet Momo the blacksmith, Ochaco the mage, Jirou the bard, Hagakure the forest fae, Tsuyu the tavern girl, and Mina the mermaid. And in this world, the true princess was Eri. Then there was Shinso, whose role in this strange place was still a mystery, lurking somewhere like a hypnotic Cheshire cat.
