The city where Death Agent Ichigo Kurosaki is located suddenly experiences an unusually huge amount of spiritual pressure. Kurosaki Ichigo and Kuchiki Rukia were ordered to check. As a result, when they arrived, the reiatsu there had long disappeared. A few days later, the Kurosaki family's hospital received a patient. She collapsed on the roadside due to hypoglycemia. As a result, the kind-hearted Kurosaki family took in the girl who had no family. Everything that happened after that seemed to gradually become weird. At the same time, the Thirteenth Team of the Seireitei Gotei received news: the princess of the royal family was missing! However, the institute searched all the world-traveling gates and found no trace of the princess going to the present world. This made everyone very sad. The Gotei 13 and the Death God agent Kurosaki Ichigo are sent to find the whereabouts of the princess. Because the princess's Zanpakutō has a particularly strange but powerful power. But no one has seen it. At this time in Hueco Mundo, Aizen is still studying the power of Hongyoku. He gradually discovered a new power that could quickly revive Bengyu. Where did the princess go? Who is the girl who appears at Ichigo's house? Is she related to the missing princess?
