I'm just laughing at the weird accent on the o in Shogun. Shogun. o. That's the proper accent. I mean, what the hell is o doing here?! It's an accent that belongs only to Spanish ( Portuguese, too, I believe) as far as I know. You don't even need an accent either, but Romanization does differ depending on which way to want to do it. I just wanted to point that out. It bothers the ever living hell out of me. 
 Lol, Island (Shima) Island??? What kind of name is this?
