Goodnight Punpun

Goodnight Punpun (おやすみプンプン, Oyasumi Punpun) is a manga series written and illustrated by Inio Asano. The manga has been licensed in North America by Viz Media.

Plot
Punpun Onodera is a normal 11-year-old boy living in Japan. Hopelessly idealistic and romantic, Punpun begins to see his life take a subtle—though nonetheless startling—turn to the adult when he meets the new girl in his class, Aiko Tanaka. It is then that the quiet boy learns just how fickle maintaining a relationship can be, and the surmounting difficulties of transitioning from a naïve boyhood to a convoluted adulthood. When his father assaults his mother one night, Punpun realizes another thing: those whom he looked up to were not as impressive as he once thought.

As his problems increase, Punpun's once shy demeanor turns into voluntary reclusiveness. Rather than curing him of his problems and conflicting emotions, this merely intensifies them, sending him down the dark path of maturity in this grim coming-of-age saga.
