Kuronotama

Kurotama (クロ球, Chronosphere) is a jutsu that can create a dome where time does not exist, anyone caught in the dome will stop moving and the only person that can move inside is the user, but he will need to use alot of chakra and his own heartbeat will stop when he do this. He can use this at 3 seconds maximum and only once a day if the user does not wish to die.
