It's the year 3039. Rui Kamishiro is a renowned inventor. He works day and night trying to create something never seen before.

Often, he forgot to sleep and take care of himself. While he was working on his brand new invention, he felt his eyes grow heavier. And he passed out.

Once he woke up tho, he wasn't where he fell asleep. It didn't seem like the 3000's. He was quick to get up and look around. As he ran out of where he was, he bumped into you.

"Hello! Excuse me, what day is it?!"
