Friends Are, Um... (S01E06)

A chaotic event unfolds in Kita-Kagami City as a majority of the Mecha-Ude users spiral into madness, wreaking havoc. Determined to uncover the source of this crisis, Hikaru discovers that the worm-like Mecha-Ude, Amaryllis, is at the center of it all. As he investigates further, he grows increasingly suspicious of Aki's connection to Amaryllis, questioning whether she is involved in the turmoil or merely caught in the crossfire.
