MIB? Seriously? I don't know how to react to be honest. XD
I gotta admit though, Satoshi looked so cool even though it was his first appearance.
When the scene switched to the lake, I thought that area looked familiar. It seems it was the same place from Onegai Teacher and Onegai twins. I remember it a bit since it's the place where Ichigo was "bird watching." It really makes me wonder just HOW old she is in this series. Also, I think that voice did sound a lot like Mizuho. I guess she left that message before she went back home.
Overall, it was a good show. =D
