If you can delay it a level, pick up Weapon Finesse at level 2 with the rogue trick, taking TWF as your first level feat. You'll likely want to dual wield wakizashis.
Rich Parents is a waste of a trait. Go with Augmented Disguise or Keeper of the Veil instead.
Invisibility from Magical Tail isn't really worth it when you have Vanishing Trick. Definitely not worth taking the feat 4 times to reach (you have to gain the abilities in order, can't pick and choose). The Disguise Self option isn't terrible, since it last the full 10 min/level, as opposed to the 1 min/level of Sudden Disguise. I'd still take Sudden Disguise, since Swift Kitsune Shapeshifter + Sudden Disguise means you could duck around a corner and become a completely different person.
Taking Realistic Likeness means you'll rarely be in your normal form, so you won't get much from the natural attacks.
Miscellaneous thoughts in no particular order...
1. I never played in a game that used feats, but Rich Parents seems iffy. You're essentially trading what could be a permanent advantage for an amount of gold that will eventually become little more than chump change.
2. In order to get Invisibility out of Magical Tail you need to take the feat 4 times. You may want to reconsider, especially because you have Vanishing Trick and then Invisible Blade... which you would get at level 10 or around the time you'd be blowing a fourth feat on Magical Tail.
3. Regarding an Amulet of Mighty Fists: I'm the one who suggested it to you before because you mentioned having two claw attacks in addition to the bite (or at least I thought you did though I didn't stop to think how you did). If you only have the bite then an AoMF isn't worth it due to the cost. I'd just make due with your bite as is; don't depend on it, but think of it as a nice bonus when it does hit.
4. I think a Monk dip would be a bad idea. You wouldn't really be getting anything from it and you would be losing Sneak Attack and Ninja levels to qualify for the good talents. Plus you can't Flurry with a wakizashi.
I'm not crazy about your feats either. Dirty fighter is to situational and rich parents nets you little all things considered, you're not a fighter looking to get the best armor at lv one after all.
Off the top of my head I'd recommend Reactionary for the initiative bonus and Cheat Death for the re-roll, though the latter does require taking Besmara as your god.
I like the initiative idea. What's the pro/cons of Besmara as a god? And most attacks I make should be within flanks. I'll be using acrobatics a lot to get into position.
Besmara is the goddess of pirates, and a goddess who's a pirate. She's geared towards a nautical campaign, thought that's not required by RAW. She's who you take if you want to be chaotic, but think Cayden Cailean and Desna are to goody-two-shoes.
If One Piece were set in Golarion this is goddess every character from Luffy to Blackbeard would worship.
