If there is any reason to take up this ridiculous Hero job, it's to make sure I can go home. Even if... [His shoulders slump, hand holding his wrench falling to his side, so he has to drag it along the street beside him.] Even if I was told it might be going through the same problems this world has. Even if I was told that I may not even get to go back, whether we solve this problem or not.

[He stops, clenching his shoulders and holding his wrench to him tightly, as if for dear life. It's all he's got of home now, really.] Even with all of that... I have to try! Right?! There are no absolutes in this or any other world!
