Arata and Yui in “Dream World and Sub-Administer”

So I'm guessing you're friends with the ninja because you don't really understand how friendships are supposed to work. She can't expect anything from anyone, so expectation is her thema. You don't get the concept of friends, so friendship is your thema. Sound about right?

Well, it's not how I would put it, but more or less. I've been asleep by myself in here this whole time. I might never have woken up if it hadn't been for you. You know, I'm kind of glad I didn't have anyone before.

Okay, so my magic undid your power and because of that, you were able to wake up and be in the material world?

Yes, that's right.

Interesting. All right, well, do you think you want to be my friend?

Your friend?

Well sure, you need more than just the ninja. I'll research that thema of yours, we'll do it together.

Yay, that's great. Big brother and I are friends now.
