Kleptomaniac Mouse vs. Clueless Earth-Boy!
Kazuto thinks this will be the best Christmas ever because he's found the perfect gift for Narue, his space-alien girlfriend. Unfortunately, when he visits the home of his good friend, Shiki, the expensive bauble is stolen by Sir Mouse, a hyper-intelligent and seemingly immortal rodent that, well, steals things.
Also on the boards is a bizarre twist on Field Day, a quirky New Year's celebration, and the secret origin of the sentient spaceship, Bathyscaphe. If you read only on romantic comedy manga with lovesick spaceships, off-kilter scavenger hunts, and very realistic toupees--this should be the one!
