Momo Tama (2005)

Blurb:
Kokonose Mutsu, a descendant of the ogres who were banished from their own island by the mythical Japanese hero Momotaro centuries ago, is determined to reclaim his family’s old glory. Fast-forward to present day: Kokonose is armed only with dubious powers, an adorable face, and a super-huge ego. He’s all set to re-conquer his ancestors' home, which has been turned into a military school for ogre exterminators. You can be sure that these hardened soldiers are well prepared for any onslaught...but can they stop laughing at this ridiculous invader long enough to put up a fight?
