At the very beginning, Kurosaki Ichigo was just a seemingly thin but热血 (full of fighting spirit) violent teenager, with the ability to see ghosts, living an ordinary life. His father ran a hospital and was also involved in exorcising spirits. His two sisters had absolutely normal personalities. There was a violent family rule that he must return home by seven every day, otherwise he would be disciplined physically. The noisy father-son relationship and the understanding younger sisters, along with a life no different from other ordinary manga protagonists. It wasn't until Rukia was kicked into the corner and looked at him in astonishment asking "Can you see me?" that the prelude was officially kicked off.
From then on, everything around Kurosaki Ichigo turned upside down, whether it should or shouldn't have.
There are two kinds of souls in the world. One is called "whole", which are ordinary spirits. The other is called "Hollow", which attacks and consumes the souls of both the living and the dead.
Rukia, who calls herself a Shinigami (Death God), told him that her job was to perform soul burials for the "wholes" and guide them to a place called Soul Society, while eliminating the Hollows. At that time, a Hollow was already nearby. His father was mysteriously severely injured, his sister fainted in front of his eyes, Ichigo's heart was beating wildly in panic, and he somehow released the Shinigami's Kidou (demonic art) on his own. For both him and her, everything was so unbelievable. He had never imagined that there were actually Death Gods in the world, and she had never seen or even heard of such a powerful human being.
Under the circumstances where there was no other choice, Ichigo obtained Rukia's abilities and became a Death God. The black clothes of a Death God, the Zanpakuto (sword) that changed form and grew larger due to his spiritual power, and the huge, monstrous Hollows - from this point on, the destinies of these two people became tightly linked together. Everything was equally without any other choice...
