Adventure Time is starting on May 6th in Japan, so here's some promos!
This one makes the show look so intense, but then tosses us the comedy. Lump Space Princess' voice made me laugh (I wonder if George Takei will be doing the voice for Ricardio again)
And then there's the OP. Finn and Jake's VAs do the song this time, which is kinda neat
Fun fact, Finn is played by Romi Paku, Edward Elric's VA in FMA.
