Isshin Kurosaki

Isshin is the father Yuzu, Karin, and Ichigo Kurosaki. He runs the local clinic, though seems to know and have influence with the chief of medicine at the hospital, Ryuken Ishida. He initially acts like an idiot, seldom acting serious except in his work and when he speaks to Ichigo at the anniversary at his mother. In the latter instance, he tells Ichigo that he does not blame his son for his wife's death ten years before the start of the series and instead proud that his wife died protecting her child. Later, after the Soul Society Arc, Kon is attacked by the newly-made Arrancar, Grand Fisher. Isshin then reveals himself as a shinigami, claiming to be of Captain-class in terms of power and quickly dispatching Grand Fisher with a single strike. Before doing so, he informs Kon that had been aware of his existence since the first encounter with Grand Fisher, citing the fact that he had never called Kon Ichigo while in Ichigo's body. After the battle, he speaks to Kisuke Urahara and the two appear to be good friends. It is implied that he bought a gigai from Kisuke long ago, presumably, as he expresses a bit of surprise at his powers returned, to have them drained using the untraceable gigai invented by Kisuke. Later, when Ichigo, Yasutora Sado and Uryu Ishida depart to Hueco Mundo to rescue Orihime Inoue, Isshin is shown talking to Ryuken, who acknowledges his existence as a shinigami. The two admit that they're not good fathers, and Isshin explains that he is tyring to be better.
