No problem, allow me to help you.
You're right, Taijutsu in a sense is unarmed combat, but under the right person it is also the most lethal, it means body arts, attacks and such are the result of your constant movements, you induce pain onto another person by using your own flesh and skin, it's the most natural form of fighting. Most of it doesn't even require any chakra, and those attacks that do just spice up the battle.
There are various different forms of Taijutsu, some are specific to certain characters, there's the Kaguya KG, there's the Raikages' lightning armour and so and so.
Within our RP yes, there's a branch of Taijutsu referred to as NB Tai, or Kaito's Tai. It was developed by a former mod who now goes by the name of Nirvana, it is specific to this RP and requires permission to be taught, the techniques in that are an advanced version of regular Taijutsu. Then there's the EIG of course which is something amazing, the absolute pinnacle of Taijutsu but as you've stated, the drawbacks are immense, if you are an EIG Master however, you can open up to the 6th gate without spending a move, AND won't suffer any drawbacks after it closes. But take one step further and boy oh boy are you in for some trouble >_>
Alright *Summons a dummy*
This'll be your partner where you'll demonstrate your ability to grasp the concept of Taijutsu, where you'll learn to be the very best dudududu. What I want you to do now is simply go up to the dummy and practice a combo of hits, it could be anything and everything, this style of combat is only limited by yourself. Kicks, punches, you know the deal. I don't want a lot of course, I just wanna see how you are.
