Does anyone know a manga like this?

try "Grand sun" :)

Just a note: I put the links below in order of my own preference/perceived similarity to this manga rather than the order I explained them.
If you're looking for a manga with a strong female lead who crossdresses as a male, I'd recommend Idol Shopping (by the same artist as Hot Blooded Woman and Love in the Mask). The story is nowhere near as good as TCP, and has little actual action, but it reads quickly and is decent entertainment.
If you want the strong crossdressing female with a decent/good story line, I'd really recommend Saver and/or Basara (I think Basara might be closest to this manga as far as plot/character depth goes, so I'd really recommend reading that one first). Though both of those are classics, so you've probably already read them.
And if you're as big a fan of female MCs who can fight as I am, I'd also really recommend Oresama Teacher. No crossdressing and only the barest hints of romance, but it will give you abs from laughing.

Hope you like them!

Oh my...I just started reading it and I feel like I've been waiting forever for a story like this. I like it so much that I'm scared cause I see a tragedy tag. I can guess how it will end...probably I'll end up crying but still I can't not read it. So, will it really break my heart without mercy? ╥﹏╥
So this is it...well, I'm not completely satisfied. I wish they would have gone a little further! It would be good a spin-off with the two living together...they are too cute, I want more!!! Am I too greedy? lol
