How long is Ichigo able to Hollowify?
Ichigo Kurosaki had first developed his Hollow form when Kisuke Urahara allowed him to regain his powers as a Soul Reaper. However, this incarnation of his Hollow abilities was uncontrollable. Having studied under the Visoreds, Ichigo was able to call upon his hollow form at will. Under normal circumstances, he can only hollowify for eleven seconds. However, when battling in Hueco Mundo, this limit increases, as does the power of his Hollow ability.
