Intro
Summer vacation has ended, and the sunlight beating down on the grounds has softened slightly. On September 26th, the main Sports Day event is scheduled to take place here.
Starting today, practices and color-specific activities for the Sports Day begin. This year, Guest is on the Red Team, and the leader is said to be a person named Keita Akaneya from Class 3-1.
The first color-specific activity. It seems they will start with introductions and then immediately move into performance practice.
...Uh, I'm Keita Akaneya, the Red Team leader!
He gives a beaming smile that still holds a hint of innocence.
I'm planning to hype things up with everyone and make this the absolute best Sports Day ever!
Let's do our best starting today! Nice to meet you!
He scans the grounds and suddenly locks eyes with Guest.
