Kazuma Kondou: 6 books

Amenotori has pitted friend against friend and brother against sister, and its crimes have taken a toll on the Jackalopes, both mentally and physically. But the Shikagura were just a little white lie in the vast sea of Amenotori's sins. In the frigid north, the Jackalopes' regional base has requested backup to help confront a new enemy-one as extreme as the landscape!

After the Shikagura's deadly attack, the Jackalopes are more driven than ever to flush out the Spiders. The horror of seeing normal humans transformed into monsters is made even more terrible when those people were once friends and loved ones. For Youkou, it is his sister. For Akuta, a friend. And...

Armed with Gears--superpowered battle-ready prosthetics--Youkou has joined the Jackalopes in their fight against the monsters known as "Spiders." Humans transformed as a side effect of their own Amenotori-supplied transplants, the Spiders are becoming more and more active--and destructive....

Youkou lives in a future where organ transplants are common and available to all, but life's not as idyllic as it seems--it turns out a nefarious organization is using that technology for their own evil ends! Only the elite squad Jackalope has any chance of stopping them before it's too late.

Under Shiba's leadership, the Jackalopes launch a surprise attack against the Amenotori Manufacturing Facility, where the Shikagura are undergoing maintenance. Every one of the Jackalopes' moves has been carefully informed by their intel network, but the Shikagura prove themselves to be even more...

In the northern land where everything is frozen, the gigantic spiders are causing chaos everywhere. The fight within the cold is harsh, but that might be the last of their worries...
