Ikkitousen: Dragon Destiny

If you like Tenjou Tenge, you might like Ikkitousen (especially Dragon Destiny). Now, I know Ikkitousen has been recommanded to death, but Dragon Destiny has way more similarities with Tenjou Tenge and is way more recommandable than the first season: better production quality and they both have stories related to some kind of 'dragon eye'. If you like Ikkitousen Dragon Destiny, you might like Tenjou Tenge. Same kind of story related to some kind of 'dragon eye' but with a slightly poorer production quality. 

both are all female and are using weapons 

Both of these anime are similar that to them there is a theme of fighting arts. Accordingly similar technics (liberation of mythical essences, etc.). The main characters in them - girls. At all not having thoroughbred relationship the main characters all equally become the friend for the friend as sisters. And in desire to protect the favourite and dear person, heroines will go on everything even if it will cost it of a life...  

In my opinion, that's what Ikkitousen should've been. Re-telling of famous war periods (the Three Kingdom era for Ikkitousen and the Sengoku era for Sengoku Basara). Different factions that beat the crap out of each other but with LOTS of action and more exciting fights in the case of Sengoku Basara. However, there's not as much fanservice as in Ikkitousen. And Sengoku Basara is pretty much GAR and over the top. 

Similar on the fact that the names have to do with the other and some of the fight scenes are similar and is a Historical anime and is the second season of Ikki Tousen so of course it would also go here.
