A simple 'watch & forget' 12 ep animation. No real story, the only thing synopsis misses is the constant involvement of wacky, perverted head ninja Onsokumaru whose off-centre presence (let-alone looks) & comments inspire a lot of the humour. 12 eps that are split in halves ie 24 mini eps. Never takes itself seriously but will make you smile if not laugh thruout. Only a single season but I think that's enough else it'd become overdone. For that reason I'd be against binge watching. No nudity.
