Read up to chapter 43 CONTENT HEAVY! Truly excellent. But, should wait until it's completed. Since it is so content heavy that re-reading it would be a burden.
It's coloured, it's historical, it's action,it's beautifully draw, it's a 5star manga, it's soooo damn good! Even if it's not yaoi (yeah,i'm a yaoi lover). It's a must read, I recommended this. Politics! Wow!
