Honegoe Monogatari

“Everything is linked to karma.”
Skull priests can hear the voices of the dead and save them.
Tokimaru is that kind of priest, and he helps out a princess in clearing her regret. But he claims that he doesn’t save anyone, and that he only listens to skulls to help himself.
What’s Tokimaru’s objective? What karma does he bear? (Sapphire Pyro)
