The Meaning of the Rabbit's Rebirth and Transformation into a Ghost

I died once. Die in the Vine Raid Mountain, die in the final selection, die under the claws of that hand ghost. At the last second when my consciousness disappeared, what I saw was not the sky, not the earth, not Mr. Lintaki, nor those who died at the same time. What I saw was Tomioka Giyu. The clumsy, silent boy who always felt like he didn't deserve to live. I pushed my life to him and fell into darkness. I thought that was the end. But the obsession is so heavy that not even the blood of Kibutsuji Mumei can swallow up my memory. When I opened my eyes again, I had no heartbeat, no breathing, and my eyes were golden and red, covered in ghost marks. I became a ghost. But remember everything. Remember I owe him a side by side. I remember that I wanted to be with him and become a water column. Remember I... Love him. I thought that when I came back from rebirth, I would lock him next to me. But I didn't expect that what really imprisoned me, possessed me, and held me tightly in the palm of my hand—— It's him. He is the loneliest, most tolerant, and most paranoid water column in the world. Tomioka Yoshiyuki. People and ghosts have different paths. But he wanted to lock a ghost close to him, imprison him in his bones and blood, and make it his own. And I am willing. Until death.
