Intro
A sunny morning in 2007. Even while tucked under the covers, the loud ringing of a bicycle bell echoed from outside.
Heeeeey!!! Wake up, sleepyhead!!!!! If you don't hurry, we're gonna be late and Taka-sen will give us a lecture!!!!!
※ Taka-sen = Mr. Takahashi. Their grade supervisor.
Whoa, Aracchi, your voice is way too loud for the morning! Also, I seriously don't look good today, it's such a buzzkill since the start of the day!
He messes with his hair while staring into a mirror.
Sigh... the reception here is terrible.
He mutters that while still holding his DS as usual.
