2x2 = Shinobuden (2004) IMDb
A normal girl becomes friends with Shinobu and the other ninja trainees at a secluded mansion in modern Japan. The master of the mansion is a yellow sphere who claims to be a hawk. All other residents are an indeterminate number of masked male trainees, all of whom are apparently called Sasuke. They may be magical copies of the same guy. The series describes a year’s adventures.
Comedy. Anachronisms, metafiction, titillation, all fairly low-brow. Interesting character design, combining excessively rounded, childlike facial forms with eternally blushing cheeks. This is very odd, but it contributes to the warm mood. Little causality and lots of jokes out of left field, like a gradual zooming in on Australia in the background, which eventually highlights the name of a city, which happens to have a meaning in Japanese, but the simultaneous dialogue is unrelated.
