Bleach - Season Two - The storyline:
The Soul Society has come for Rukia, to arrest her for the crime of giving her powers to a human. Though Ichigo tries to defend her, he proves to be no match against her brother Byakuya, the powerful captain of Squad Six. To save Ichigo, Rukia surrenders herself, telling a now-powerless Ichigo not to follow her. But Ichigo’s not the type to abandon a friend, and after regaining his powers with the help of the mysterious Urahara, heads to the Soul Society with Chad, Orihime and Uryu to rescue Rukia, who’s been sentenced to death.
But battling the various, more experienced Soul Reapers, including the powerful captains and lieutenants, and training to master the final released form of a zanpakuto known as bankai, are the least of Ichigo’s worries. It seems that there’s a conspiracy brewing within the Soul Society, with someone plotting to gain power that would allow him or her to take over. But the true identity of the mastermind, as well as his /her goals, are not what anyone is expecting and will only be the start of things to come.
You still have to start from the beginning to really enjoy the story, but the Soul Society Arc of Bleach made things interesting and intense. All the elements needed for a great anime series in a buzzing kids world.
