"At that moment, a girl fell from the sky. The girl was Senjougahara Hitagi. To be truthful, she probably didn't fall from the sky. She'd probably tripped on the stairs and fell backwards. I could have dodged it, but I chose to catch her and break her fall. It seemed like a better choice than dodging. No, that was most probably a mistake. Because... Because Senjougahara, whom I caught and hence stopped her fall, was very—impossibly light. No kidding, she was mysteriously, eerily, light. As though she wasn't even there. That's right. Senjougahara was so light, it was as if she had no weight."
