Yoite

A sixteen-year-old ninja serving within the Kairōshū, this tragic figure wields the devastating "kira" technique. By injecting their ki into an opponent, they can manipulate internal energy to shatter bones or cause fatal explosions from within. However, utilizing this forbidden power demands a heavy price, as each use drains the user's vital life force. This slow depletion results in the agonizing loss of all five senses, ultimately leading to an inevitable and lonely death.
