Yeah, if there is MIB, then there should already have been alien contact already...
Then again, everything in the climax about Lemon was facepalm-worthy though. Oh when the car transformed...
Har har.
So in general, it was... kind of disappointing. To the half-way mark, it wasn't bad, but then they added some new characters and then they went into the whole alien thing, which wasn't interesting at all. Because of the setting, they had to eventually cover the topic, but that is why Onegai Twins was better. It didn't have to bother with the foggy (rather, convenient) alien settings like they did here. Lemon was just used as a plot device throughout the entire thing. It could have been taken as a joke at the beginning, but it really stood out in a bad way near the end.
Another problem was the main character's lack of......... anything. Not attractive in any way... All of the characters' romances were love at first sight, and at least Tetsurou looked good, compared to the seaweed glasses.
And they never really had much closure on Tetsurou and Kanna (and the other girl), which honestly was more interesting than the main pair ever could be.
So in general, a disappointment. Not a bad anime, but forgettable.
I did name a Shiny Gallade and Shiny Gardevoir Tetsurou and Kanna though, from hair color.
