The Dangerous Transfer Student

The Dangerous Transfer Student marks the arrival of Lady Rurichiyo Kasumiōji in Karakura Town, one of the key characters to the Kasumiōji Conspiracy.

Prologue
In the real world, a Senkaimon appears, and out of it steps a man carrying a girl whose face is covered by a royal hat, and another man who is following next to them. They look around briefly, and assume that the person who is delivering their items hasn't yet arrived, as there is still time to dawn. The girl looks up momentarily, stating that she is hungry.

The Noble Arrival
Meanwhile, Ichigo goes about his normal life and finds out that his neighbor suddenly moved away. When Rukia gets notified of Hollows in the city, both she and Ichigo leave school to fight them. They find it odd that more than 50 Hollows have appeared all at once, and they have no choice but to split up to fight them. Back at the riverbank, one of the Shinigami reports to the girl that he can’t shop for food because their Gigai hasn’t arrived yet.

The girl becomes impatient and tries to take off her hat, but the Shinigami stops her because that hat is keeping down her spiritual force. He instead urges patience until her special gigai arrives, and for now he’s more concerned about the important experiment that the other Shinigami is off preparing. While he’s turned away from the girl though, she runs off on her own. Walking through town, the girl happens to see Ichigo battling the Hollows and calls to him. Seeing that she’s a soul, Ichigo heads down to her to investigate and is confused when she talks about wanting to eat. As she approaches him, the girl trips and her hat falls off, and Ichigo ends up helping her back up. However, his attention is then turned to the Hollows, so the girl gets annoyed because she’s still hungry.

She grabs onto Ichigo, and while the two are struggling, her Shinigami guards find her and grab her. Unfortunately, they’ve brought with them a horde of Hollows that subsequently bury Ichigo, and Ichigo decides to initiate ban kai to quickly get rid of them all. The guards and the girl disappear while he is fighting, and the battle ends only after Ichigo is joined by Rukia, Ishida, Sado, and Inoue. Ishida in particular had sensed an unknown Shinigami’s spiritual force and had figured out that the people Ichigo met had used bait to lure out the Hollows.

New Development, the Dangerous Transfer Student Appears
That evening, Kon informs Ichigo that they have new neighbors. These new neighbors turn out to be none other than the girl and her two Shinigami guards, but when Ichigo confronts them, the lead Shinigami refuses to tell him who they really are even though they already know who he is. He even sets up a barrier to keep Ichigo out of the house. Since the girl and her guards are now using gigai, Rukia goes to Urahara’s store to ask about it, but Urahara isn’t there, and the others decline to tell her anything. The following day at school, Ichigo and friends are shocked when the girl and her guards show up as new students: the guards’ names are Kenryū and Enryū, and the girl introduces herself as Rurichiyo Kasumiōji.
