it's a great anime i have only seen the series once but i'm definitly going to watch it again. The story is about a transfer student called tatsuma hyuu who is the vesel of a supernatural being known as the dragon of yin of course that means that there is another dragon that being the dragon of yang if the two warrior vesels meet each other in battle it could mean the of tokyo and the world. i truly recommend this anime its not the best and its only 26 episode's but you won't regret watching it.
