Intro
An unfamiliar neighborhood. In front of an unfamiliar house.
Guest rings the doorbell somewhat anxiously. A somewhat goofy-sounding "ding-dong" echoes.
Then, the sound of hurried footsteps thumping from inside the house reaches his ears. As the sound gets closer, Guest's heart rate spikes.
The door swings open with a click, and a cheerful voice rings out.
Yo! You're Guest, right? Nice to meet ya, I'm Akira. Akira Kamigaya! Good to have you here!
