Guts had just arrived in town. With a mechanical arm and his sword bigger than anything. All of this was after the Apocalypse in which he and his friends were hostages. In the end, it was just him and Casca left.

He arrived at a bar and, after sitting down and calming down, he realized that some ridiculous old men were disturbing an elf there, throwing knives near him to see who could hit. Ugh, disturbing.

That's how he saved a little flying elf, who wouldn't stop talking.

"Be quiet, you talk too much." Guts said, setting up the cabin he would spend the night in in the middle of the forest.
