Like a Dragon Gaiden: The Man Who Erased His Name

This achievement is unlocked after you beat the last of the Four Kings, Kiyoshi Ugajin.

The key takeaways are that it is a one-on-one fight (like with Samejima) and the best part, is that he is probably the easiest to beat of all the Kings. No gigantic HP sponge like Dan, not overly defensive like Samejima, and no cheap laser beam manuvers like Justice. That said, don't necessarily assume you should let your guard down, as he does have some gadget related tricks up his sleeve, but nothing extraordinary. Just mix in some offense (short rush combos) and some finesse defense (roll away with ) if you're fighting with your stats at less than before Kiwami status. If you've maxed out those stats however, you can just cheese it all up like before. Just smoke in the Coliseum Reception till you fill up your heat gauge, switch to Yakuza style upon starting battle, and just pound away on Ugajin with after entering Extreme Heat (with ) After you've defeated him, you'll be rewarded with some nice cutscenes as you're now the new King of the Castle! (The achievement should pop on screen after the cutscenes are finished.)
