Zyro, Shinobu and Maru visit Tsubasa and Madoka at the headquarters of the WBBA and are informed about the Synchrom. Shinobu learns that Zyro's Samurai Ifraid was given to him by Gingka Hagane, which leads to Shinobu leaving the group.
The next day, tag team battles are being held at the Bey Park. Shinobu faces off against various Bladers and beats them all, including his partner. Next a new fire type Blader named Ren Kurenai battles against several bladers and, like Shinobu, beats all of them, including her partner. But she uses her own version of Zyro's special move.
