Place it at the very beginning of your edit as the welcome, then follow it with Ara Ara for an anime reply before the main clip starts. Use Okay Let's Go next when the action begins, so the greeting, the tease and the start form one short sequence.
About this sound
This is a very short Yukkuri Reimu voice clip, lasting about one and a half seconds, saying the Japanese phrase 'Yukkuri shite itte ne' in a flat, synthesized voice. It feels warm, relaxed and a little cheeky, like a laid-back invitation to stay a while. It is the Yukkuri version of Reimu Hakurei, the shrine maiden character from the Touhou fan meme.
