Reading Hogwarts in a Superhero World

Mori always thought he was an ordinary person. Even though he was a wizard who had transmigrated here with a cheat. So he kept a low profile and lived from day to day, diligently using his cheat System to repair buildings, fix up cities, and rebuild New York, doing logistics for his Avenger teammates. Until one day, Thanos attacked. Mori was hauling bricks on the ground, watching the purple potato man crush the building he'd just finished repairing. Enraged, Mori hit him with an Avada Kedavra. And then world peace was restored. The Avengers: What? - Captain America always thought his little boyfriend was a cute little wizard who sat on a soft white carpet, draped in a shawl and reading in front of a towering bookshelf, the sort who would burst into tears if you teased him. That was until his little boyfriend started using the tiny wooden stick he called a wand to wreak havoc, making countless villains howl in despair. "We need to talk, darling." Steve folded his arms, preparing for a serious family meeting. His little boyfriend came over at that, smiling as he kissed Steve's chin. "Talk about what? Kissing? I just had a blueberry candy." Upright and principled Captain America: "..." Upright and principled Captain America: "...Kiss me." Never mind. What could matter more than the fact that he loved him? The CP is a certain sweetheart. The skills may differ from the original spells, and there may be some OOC moments, so don't sweat the details. There are a few past-life and present-life Hogwarts scenes, but not many. Theme: Even a lousy card can become overpowered.
