   Summary

   “Open your mouth,” Ume orders.

   “Ngh. Why –”

   “Just do it. I have an idea.”

   Gyutaro’s not altogether certain of the quality of his sister’s ideas, but that’s no reason to hesitate.

   In the lowest regions of the Entertainment District, the young and the infirm are little more than mouths to feed. Gyutaro knows it well. But with Ume by his side, he finds it's not the worst thing in the world to be.

   WARNING for sibling incest.
