Snowball Earth vol 2 is the continuation to the mech/kaiju series starring Tetsuo. This volume focuses on Tetsuo's arrival to the home base of the strange adventurers Tetsuo inadvertently saved in volume 1. After years of making their way across the barren snow fields that was once Earth, these survivors made their home in an old school building miraculously intact amongst the ice. We also get a glimpse into what's happening in the surrounding area as a group of mysterious and hostile "kaiju pilots" are making their way to the settlement as well.

This volume delves deeper into the immediate destruction of Earth when the first humanoid Kaiju arrived and it became clear that the war front in space had either failed or would never return. Humanity faces extinction and starvation, forced to eat the kaiju meat to survive. Some humans get sick and die from this meat, but some gain the ability to telepathically communicate with the kaiju themselves. Volume 2 introduces this concept and focuses on both the chief of the people Tetsuo stays with and an engineer in the settlement who wants to get revenge for her mother's recent death.

Volume 2 was interesting. I am more and more interested in these sorts of ongoing apocalypse stories. While I find Tetsuo sometimes annoying, I am enjoying the worldbuilding of this series. I have two complaints. One the frankly unnecessary boob shot at the beginning of the volume (like why?). I don't mind nudity in manga, but it seemed like unnecessary fan service. Two: please villain stop touching your eyeball. I hate it ew.

In this second volume Tetsuo meets more people and settles into life at the human settlement. Just as he's starting to fit in he has to face off with people he thought were part of humanity's heroes.
I don't typically read this type of genre in manga, but he plot is intriguing and I'm enjoying learning about the aliens that have attacked Earth. I may enjoy this series more as it continues, but I'd like to see where the story is going first.
