Is it really strange? ( Urashima tilts his head to one side, curiously, ) If you treat something well, it stays strong and good for you, doesn't it?

Doesn't your sword do the same thing?

( Surely it's saved his life because he's treated it well and it's remained good for him. )

Like this, I can help my master do a lot more than fight. I can help him do chores and play with him too... but even if I didn't have this body, I'd still do my best. It's the same for everything.

( Of course, it seems obvious and simple to him. The idea that things might feel differently in other worlds doesn't really cross his mind. )
