Raideen is a 2007 remake of an earlier super robot anime. Junki Saiga
(Masataka Azuma) has a gift for mathematics despite being relatively
average in high school. However, he once merged with an ancient robot
from underneath a triangular mountain. He has to keep these two aspects
of his life separate throughout 26 episodes. That's not as easy as it
sounds. Saiga will certainly have to work hard to make sure that his
life doesn't crumble under so much responsibility.
