Flying Dragon 【飛竜 Hiryuu】 (Sai. Vol 3 - Continuous) ☆ Creature made by the combination of science and youkai magic, and with them Kougaiji and the others can use the sky paths, and quickly show up before the Sanzo Ikkou. However, it seems that Ukoku Sanzo travels between the East and West using a different method. ☆ Another example is Hakuryuu. He is a creature created in an experimental “combination of science and youkai magic”, and so has crimson eyes like the flying dragons of Houtou Castle. ☆ Hanyou and flying dragons are are both “taboo existences”.
