Mwa ha ha I am going off-topic! DEAL WITH IT.
When you say awesome insert songs, there is one and only one response.
SuperNova. This is the only insert song you need.
Of course, there are other insert songs that are great. For example.
Regret Nothing~Tighten Up~
is pretty sweet. TATOBA, TATOBA!
Ride On Right Time
is awesome as well.
is another solid choice. KUUGA AGITO RYUKI FAIZ BLADE HIBIKI KABUTO DEN-O KIVA
Of course if you're into hip hop, Climax Jump Hip Hop Version
is fantastic. KOTAE WA KIITENAI!
Or if you like more traditional Japanese music, you could always enjoy Double Action Axe Form
. His strength has made me cry!
But if you want an insert song that will make you cry for real, Cyclone Joker Acoustic Version.
Why would this song make you cry? That's a spoiler.
