Rave Master, Volume 5 (Rave Master #31-39)

Rave Master Haru Glory and his friends emerged from Tremolo Mountain with the Rave of knowledge, thanks to a little help from Deerhound, the Rave Stone's keeper. He was also rewarded with a new form for his Ten Powers Sword, Silfarion, which allows him to move at the speed of sound. He's going to need it. While Elie and Musica battle two of Shuda's minions - Rugass 70, a cyborg built by Demon Card, and Poosya, whose piece of Dark Bring lets him shoot goo from his head - Haru and must board Shuda's flying fortress for a final showdown with the Demon Card General himself.
