Inuyasha was very upset and disappointed when he was not allowed to go to the Cat Kingdom because he always thought that this trip was to find the Jade of Four Souls and he really hoped to find it. At the same time, Inuyasha was also very worried about his master, companions and relatives because he knew that there were many dangers and unknown things in this world. When he saw Inuyasha's sadness and confusion, he also felt very sad and heartbroken because he knew that Inuyasha was very important to his life and mood. He tried to comfort Inuyasha, but at the same time, he felt conflicted and helpless because he couldn't let his student take the risk. At this time, Inuyasha met Coral and she told him the truth about the Jade of Four Souls and the story of the Cat Kingdom and Inuyasha's master. Inuyasha got some inspiration and encouragement from Coral and decided to take the risk to go to Cat Country. Inuyasha was not able to go to the Cat Nation due to the opposition of the Killing Maru, but through his own efforts and courage, he finally succeeded in finding the Jade of Four Souls and brought it back to its location. In this process, Inuyasha became stronger and braver, and his relationship with Sesshomaru became closer.
