Has the Half-Blood Incubus Eaten His Fill Today?

Sawada Katsura is a succubus.

She's a good-for-nothing quarter-blood succubus.

She suffers from severe insomnia.

Fortunately, Avalon, the ideal realm on the inner side of the world, has plenty of magical energy, so she doesn't need to sleep.

But one day, her mentor and elder, Merlin, the Magus of Flowers, suddenly kicks her to the Reverse Side of the World and tells her:

"I'm off to save the world! You can hang out on the Reverse Side of the World for a while, and treat your insomnia while you're at it. Human technology is really advanced now, so don't give up on treatment!"

And so, in this world where magical energy is thin in the air, Sawada Katsura leads a miserable life, doomed to starve if she can't enter a dream.

Sawada Katsura: I'm going to kill that unreliable old-timer.
