I can't do it... I can't go so far as to hurt and kill people to become a cool 1st grader, I'm just not capable of it.

I thought I didn't have any choice but to become a 1st grader. But I was just lying to myself. The only thing I'm capable of is hurting others. Then I'd rather not do anything!!

You hate yourself. That's why you hurt others. Those who inflict it know pain better than anyone else.

This doesn't involve you, Hatena-san! You don't understand anything!!

So what if it doesn't involve me!!

If you don't do anything I won't forgive you... I won't forgive you for the rest of my life...

Listen Yuuki-kun. Use the Math Machine again and put an end to this. Why are you going to grade school? Why are you becoming a 1st grader?

And when you've found the answer, come back to me.

Promise me... Goodbye...

That's a 1st grader kiss.

We'll continue when you return.

But this is something that you decided. It has worth, Yuuki-kun. It's about you.
