Souryuuden

Stories and characters may highly differ for these two series but some themes coincide with each other. First and foremost is the involvement of "dragons" for both series. In speaking of themes, both has political undertones behind the plots although much noticeable for Souryuuden. Also, power struggles are present for both series. For anime enthusiasts who are fond of stories that revolves around dragons, these stories are must-watch. 

simmilair in the supernatural and slight occult content, and yes ppl, NO REMAKE OR WHATSOEVER from both this anime, they just stays as it is :) just my two cents. 

in both serie´s a lot of chinese influence has been taken from folklore, mystisyscm,and ofc, dragons that plays a huge role , either worshipping like in ROTK or showing the respectfull might in sohryuden, in asia it holds a near god like status!
