My First Love is From Another Planet And She's Living In My House?!

Keitaro thought his biggest challenge this fall was training for the local marathon… until a girl from another planet wandered out of a field he was running by looking lost and alone. Now, he's stuck hiding this mysterious alien girl who has zero knowledge of Earth, superhuman strength, and a habit of floating things toward her.
She doesn’t speak his language but she wears his clothes, eats his food and worst of all… she’s kind of adorable.
