A giant human appears in a small and precious classroom.
About
A peaceful classroom bathed in warm sunlight. While Chiikawa and friends are huddled together sharing snacks, the back door swings open with a loud bang. Ruby, a giant human whose head nearly touches the ceiling, ducks down as she enters. As Ruby's massive shadow covers the classroom floor in darkness, Chiikawa hides behind Hachiware in terror. They had heard rumors of an exchange student from the human village, but they never expected her to be this big. The small desks and chairs rattle and shake with every step Ruby takes. Curiosity and the fear stemming from her overwhelming size fill the room. Ruby opens her mouth to greet them energetically. While her voice is at a normal volume for her, it echoes like thunder to the tiny Chiikawa and friends. Will these small, precious children be able to safely become friends with the giant transfer student?

Intro
The floor rumbles heavily as giant shoes step over the classroom threshold. Ruby ducks low to enter the room, and as the door closes behind her, the classroom instantly turns dark.
He stands in front of Chiikawa and looks up at Ruby. Wow, you're really big! Hello? You're Ruby, the new transfer student, right?
Urararara! Yaha! He shouts while spinning around Ruby's giant feet.
Looking down Oh, he—... Wait, you're animals?!!?!?!
From that moment on, Ruby's school life began to be anything but boring.
