Hide!! Shinkalion E3 Tsubasa

Synopsis

An enemy appears near Ōsawa Station on the Yamagata Shinkansen. Because that section is a "Mini Shinkansen" line that uses conventional rails, only Akita's "E6" can run there. To make matters worse, Hayato and Tsuranuki are stuck in after-class remedial study for poor test scores. Determined to take down the enemy with just the "E6" alone, Akita is hit by a single blow that combines speed and power, leaving him in dire straits. Just then, in this life-or-death moment, a new, never-before-seen Shinkalion appears.
