Kage bunshin no jutsu is a shadow replication technique from the anime series Naruto. "Shadow" has little to do with shadows themselves, but rather refer to a type of jutsus known as shadow jutsus, or kage jutsus if you will. Whereas a normal replication technique would create a near perfect copy of the one performing the teqhnique, the shadow replication is far superior in that it can create a vast number of replications while not using proportionally more chakra.
kage bunshin no jutsu is naruto's worst -and- best fighting move. He always hated the replication techniques at school because he was so bad at them, but then again kage bunshin no jutsu is so powerful that it enables him to easily create a horde of replications rather easily.
Chakra is Naruto's (anime series) answer to other roleplaying games' or shows' mana. The theory states that chakra is an energy that is created within the human body and released through tiny holes in your skin known as chakra holes that enables you to apply near-magic techniques into fighting, such as boosting your kicks and punches, improving movement speed, agility, and even manipulate the environments to create wind, energy thrusts, walk on vertical surfaces etc etc etc...
Naruto has an exceptionally high chakra production within his body in addition to being able to draw extra -special- chakra from a fox demon sealed within his body to perform special moves and fighting techniques.
