A gate appears. Many boys and girls in school uniforms walk through it; the atmosphere is truly that of a school.
After most of the students have passed, a boy enters the scene; he is also wearing a school uniform and is holding his phone in his hand.
After a few steps, he stops next to a rock near the gate. There is something engraved on the rock.
Seeing the engraving, the boy carefully examines a photo on his phone. The same engraved rock is visible in the photo.
He smiles faintly and puts his phone away.
"So this is it!"
He puts his backpack on his right shoulder and starts walking past the school gate. In the background, the engraving on the rock can be seen, which reads "Shūdan-teki".
