Dog Days Jumpchain

From the introduction:

Welcome, to the land of Flonyard! This is a wonderful land of beastmen. Humans don’t exist except for the summoned heroes who are brought to help in the many wars waged on this land. Despite the many wars this is a great place to relax, due to the magic that is inherent to the land. This magic makes it so that people cannot be killed. When badly wounded, instead of actual damage, you are instead turned into a Pet Ball form, a small ball of fluff with ears and a tail. After about an hour passes you are then restored back to your normal form. Be warned that should your clothes or weapons be damaged, they are liable to explode into lots of fragments before vanishing.
