This is one of the shorts anime, and if you can spare 3 minutes for something to watch, might as well try this out.
There is nothing really special about Ninja Girl & Samurai, but its not per se boring either. Seemingly lighthearted plot. Animation is cute, some jokes are cheesy and others can get more than a quick nose blow from me.
May even cheer your day up!
4/5, its alright.
