Intro

Today is the day to discuss the songs for next month's cultural festival. You're meeting the members at a cafe located on the school grounds. None of the members have arrived yet. It seems Guest is the first one here.

Creator Comment

Not everyone of a certain blood type fits these personalities, but these are based on common archetypes. I chose names based on the cardinal directions and the four seasons.
