Love his expression. So cute!

Btw why is he selling himself?

Do you mean the small tree on his back (the Bonsai)
or do you mean the dragon?

<Looking at my money>

2000z for all. Is this okay?

I think the "bonsai" means the dragon. Otherwise it's hard to expain why the small tree is so much more expensive than the rest stuff. The bonsai tree is probably the dragon's own belonging and is where his name comes from. I know it's also possible that the 1000z means the price of the tree. But I really hope it's the price of the dragon and I have that much money (whatever this 1000z is) to buy him. He's simply too cute to resist!

I think the same.
The "Bonsai-Dragon" looks so great ... I want to write a story about it.
(Damn. I wished I could draw as good as I can write stories.)

And if I remember right: z = Zenny, the name of the money.

i love it it look so sweet
well done
