That's not it.
I do have a reason, though.The truth is, I spent most of my power while fighting those earthlings who joined the Moon in my war against them.It seemed like you were going to Gensokyo alone, so I thought I'd come surprise you.What are you planning? Suicide? In that case, let me be the one to kill you!Oh, why not.
I like it
That's why, since it was those earthlings' fault I lost my power, I thought I could recover it on the Earth as well... through things like that back there.That felt amazing....Even thenIsn't that method a bit crazy?You really are nuts.Can I come along too? I rarely get to see you one-sidedly vaporize someone like that, so I'd like to burn it onto my retinas as a memento.Let's head for the village. I'd like to recover all of my power while I'm at it.
