Also Called


User possesses a rapid development rate, allowing them to permanently push back their limits within minutes when continuously reaching them, be they physical, mental or supernatural. It makes them particularly fearsome opponents both on the short and long term, as they improve fast enough to surpass their opponent during battle quickly, and their numerous improvements endlessly accumulate during their lifetime. Their growth rate, however, tends to slow them down due to its challenge-based nature gradually, and their limits are becoming increasingly harder to reach the stronger they become.




  • Requires concentration to build up and consolidate their growth, thus vulnerable to focus-breaking tactics.
  • Requires users to continuously reach their limits, which grows increasingly harder the more they develop.
  • Users may be defeated before they can close the gap, if it is too wide or their opponent rushes for victory.
  • The constant over-exertion to push past limits may be taxing on one’s body.
