Naotora is more melee and is a kick-mania. Which in this case, fits DOA more.
And if you wanna talk about playstyle, try Samurai Warriors first. You'll see more reason why Naotora is chosen other than having round boobs as reasoning.
Warriors/Musou veterans would know that Samurai Warriors fighting system has more depth and more purpose than DW. The only DW that has meaningful fighting system was Multi Raid/Strikeforce and people were complaining because it's too hard and complex.
If you wanna talk about personality, Lu Lingqi, Guan Yinping, and Naotora are all retarded boring morons with two of them being overly proud of their daddy and the other has I'm-sorry syndrome.
And please, TN don't revolve around FSD and western audience. Hate them all you want, but they priorities their fellow countrymen first, just like any other developer/publisher out there.
