Awaken is the most important thing to power up a character. Once the character reaches its max level, it can be awakened to increase the star level and stats. Additionally, some of the characters acquire secret techniques, which are special moves requiring more chakra than Ninjutsu, as being awakened.
What are needed to awaken?
Awakening requires specific awakening materials by characters. For example, Naruto Uzumaki ( The Worst Loser ) at star level 3 needs Awakening scrolls ( Heart Book ) to be awakened.
It also costs Ryo, which was a currency of Japan in the past. A player can earn Ryo by succeeding missions and as reward for deceiving conditions during missions.
