Lios Likhovich, the pacifist forest-elf who enjoys his laid-back life.
Mei Rokuhara, the proud warrior of humanity who comes from a future 1200 years ahead.
Their meeting in that forest became the fuse of the most unusual of adventures, and also fueled an unseen mutual struggle: That of an elf disguising as a demon, and of a human pretending to be a robot, who by a turn of fate, find each other attractive–unusually so.

To save the hopeless future where the world goes extinct, they must go to a convenience store in the capital, and find the Elixir of All Woes–the potion that grants unlimited power.
Along the way, they'll pick up a nice zombie, a bratty succubus, and a random kid?

So onward they march. There will be struggles, there will be battles, and plenty of blushing faces. But no matter what, they can't fall in love with each other.

And of course, let's not forget the ever loyal horse Bahamut.
