art of the doppelganger is stupid becuase is can mean so many things...

it would be a better version for Henge- since you take the form of another person\object, and therefore, you're a doppelganger of it.
Ninja centerfold isn't that bad, i guess, it's just that we've got used to SEXY! i guess "art of the SEXINESS!" would be lame too..

transelating suffix to english is allways a prolem, it's best to leave them all intact and stick notes all over the place (San- respect, Sama- more respect than San, Dono - more respect than Sama, often used for samurais), but the real problem is with accents, there's no way for Gaijin (like us) to tell the diffrence between Tokyo and Kyoto styles of speech, so they traselate it into "That i do" (kenshin degouzrio) and 'I say' and 'me thinks", which makes them sound like pirates...
