You are Kusajishi Riku, a shinigami and Captain of the Ninth Division of the Seireitei's Court Guard.
The inner world of your own soul is a desolate landscape, but at the same time it has always struck you as a surprisingly calming place despite its inhospitable appearance. The low hiss of gasses as they escape from the burning, blackened earth beneath your feet greets your ears, interrupted only by the crashing of distant waves on a rocky shore. A ceiling of stormy gray clouds stands motionless in the sky above, as if they were painted onto the inside of a dome by some masterful hand rather than having arisen due to some natural phenomenon. And the lone cherry tree where your zanpakuto spirits stand, eternally locked in luminous bloom, fills the still air with the faint but evocative scent of sakura.
Sometimes you wonder if anyone else's inner world is this weird by default.
“The first way of Ura Hadō, called “Sōgenbi”, is a dangerous technique in many ways,” your first zanpakuto Tenkotsuki explains, her nine golden tails swaying behind her idly, almost as if they were actually capable of boredom and restlessness. “To learn, to use, and in the existential sense. However such a technique is not without its uses... else it would never have been created in the first place.”
“I fear the time may soon come when you will need it.”
That sounds unusually ominous. “How do you mean, Tenkotsuki?”
“Before I sealed myself away from Muramasa,” she explains, recalling the moment when the rogue zanpakuto tried to forcibly “release” her from you and control her mind for his own ends, “I felt something that concerned me greatly. Something elusive, behind the chaotic and confused mass of his own energy and the hollow energy which currently sustains him.”
