Kirinmaru's Ship

Kirinmaru's Ship is a location that appears to the residence of the aforementioned Beast King of the East and his family.

History
After being defeated by Tōga, Kirinmaru returned to his ship with Rion. Years later in the Kamakura period, Konton and Kyūki would report to Kirinmaru on his ship. Kirinmaru also had the Shikon no Tama in his possession and kept it in his office. Kirinmaru then fell asleep for an unknown period of time and was awoken by Zero after Tōga's sons Sesshōmaru and Inuyasha destroyed the Grim Comet where he learned that Sesshōmaru had fallen in love with a human woman and had half-demon twins.

After Tōkotsu's and Jakotsumaru's death, Kyūki flew to Kirinmau's ship where he sat on his throne and ate grapes while listening to her report. Kirinmaru was reading and assured Zero that Riku will be able to handle the daughters of Sesshōmaru and their cousin Moroha. Kirinmaru stood on the bow of his ship and intercepted Tōtetsu, who was leading the girls to his ship.

After his battle with the half-demons, Kirinmaru was reading in his office when Zero told him she was going out and they discussed the half-demons. Standing on the bow of his ship, Kirinmaru saw through the eyes of Osamu Kirin that the Grim Comet has appeared in the Reiwa Era.

After battling the half-demons again, and killing Setsuna, Kirinmaru retreated and saw through Riku's eyes that Setsuna had been revived. Later, he rested on his throne, lamenting on the injuries that his rivals granddaughters had inflicted on him. He then went to sleep, so he could see Rion in his dreams through the Yume no Kochō.

Kirinmru left his ship in search of Akuru, and didn't return until Osamu came to the Feudal Era with the Grim Comet. As Osamu slayed various demons, Kirinmaru stood on the bow, lamenting the end of humanity. He then fell asleep on his throne after Osamu drugged him, and woke up just in time to see Osamu and Rion disappeared into the Grim Butterfly.

Kirinmaru left his ship to try and save Rion, but never returned as he was finally able to let go of the past and he and Rion passed on together, leaving the ship abandoned until the half-demons and Riku used it to travel to the Iyo Province in Shikoku. With Kirinmaru and his family all dead, Riku is presumably the ship's new owner.

Physical description
The ship was massive with a castle as its bridge. It had giant white flags for the wind to catch. The hull was clad in metal. The interior had two main areas.

The first was Kirinmaru's throne room, which had purple carpet leading up to his chair that was red and brown. Beside the chair was a small round table on which Kirinmaru would often keep grapes on to eat.

The other place was Kirinmaru's office, which consisted of carpet, a long wooden table with chairs. On the far side was a wooden desk and chair. Off to the side was a wooden stand where the Shikon Jewel was sitting when in Kirinmaru's position.

For years, the ship landed on the water and has an anchor.

After the Grim Comet was brought and before the Grim Butterfly has come, the ship can fly and sail.

After the Grim Butterfly was destroyed, the anchor didn't drop when taken to Iyo Province.
