I must say that this anime started out great. The twisted rivalry plot is one of the strong point of Basilisk. In each and every episode in the anime you will feel the curiosity and the tension in between the two sides. When it seems that one side finally has the upper hand, the other side will unexpectedly get back at them and gain the upper hand instead.. this goes on and on.. I really enjoy watching the first few episodes..
