We start with our main protagonist, Shichimi, bidding farewell as he readies for his journey into Edo (on our Earth, Edo was the old name of Tokyo before it became the capital of Japan). His mother has just died, only leaving him a walnut and a request for him to go to his half-siblings. Shichimi bids farewell to a sternly old man, who is a firefighter. We can tell this from the symbol on his cloak. This symbol is also on Shichimi's cloak. Upon reaching the town of Edo, Shichimi meets a mysterious man, who ridicules the peace of the world as an illusion.

From ryColaa:

Reputation is everything in a world of icons and popularity contests. So why not score some points here and there by being the nice guy? This is the way Kang Shin-gi legitimizes the fake personality he has everyone believing. Armed with his above average looks and a (completely false) angel-like personality, he has every girl in school head over heels, and all the guys looking to him for guidance. With the exception of having a screwed up cross-dressing devil for a dad, Shin-gi’s life is absolute perfection (*cough* of lies), until one day, Um Seung-hui transfers to his school.

While being a complete martial artist freak, she also likes to fib just a little in front of those who know her… you know, like acting like she's just a scared little girl who'd play with kittens rather than break brick walls with her head! After all, how can anything go wrong when you're as cute as Seung-hui?

Fate has brought these two masters of lies together, and the two must battle it out to see who will be crowned the undefeated heavy-weight champion of fakeness!
