Shadow Star Narutaru

The First Black One (1x3)

:

Fast friends Shiina and Akira, along with their shape-shifting alien pals Hoshimaru and Ensof, join together and try to figure out the mystery behind the recent attacks on Shiina's father's aviation company. In a lush forest they find the culprit - a teenage boy named Tomonori Komori with command over a deadly sword-shaped "shadow dragon". But picking off jet pilots is only the beginning of his twisted schemes, and murdering the two meddling heroines is his next goal.
