In this short scene, we learn that we're introduced to a new character, Subaru. He's not exactly a household name, but he's a good-looking guy who's got a lot of good looks. We're also introduced to some of the other characters in the story, including the narrator, who is a bit of a mystery to us. The narrator asks the audience to imagine what it would be like to be in the middle of a big action scene with a bunch of other characters. The audience gets a good idea of what the action will be like, and they're all excited to see what it'll be like. We also get a little taste of what's to come in the rest of the story.
