Snowball Earth manga volume 6 features story and art by Yuhiro Tsujitsugu.

Femlar, a man-eating kaiju controlled by Nadare, attacks Mishima Mall just before the survivors relocate. With Tetsuo out of the cockpit after a misunderstanding, Nayuta pilots a damaged Yukio to engage Femlar alongside Ao and Land of Men, but the childlike kaiju may be too much for them to handle. When all seems to be lost, a strange beckoning cat may prove to be the key to unlocking Yukio's final form - but at what cost?
