Tamachen!!

Komachi Himeno is a bright, hardworking, and undeniably cute student who keeps herself busy with everyday school life. In stark contrast stands Onigawara Nozomi, a classmate whose fearsome, monstrous appearance and intimidating physical strength keep the entire classroom at a distance. While everyone else avoids him out of sheer terror, Himeno shows unexpected courage by selecting Nozomi to join her assigned cleaning group, treating him no differently than any other student. However, this small act of bravery sets off an unforeseen chain of events. Later that day, while walking home, Himeno suddenly realizes that Nozomi is following closely behind her. Overcome by panic, she attempts to flee, but the desperate chase ends in disaster when both students tumble down a flight of stairs. When they finally recover from the fall, they are confronted with an impossible reality: their souls have completely swapped bodies, leaving them trapped in each other's lives and forcing them to navigate a bewildering new existence.
