Akuma ga Machi ni Yattekuru: Kyoufu!! Buta no Machi The Town of Pigs

Synopsis

One night, under a blood red moon glimmering with demonic beauty, a group of devilish creatures armed with axes and spears came riding into a quiet city on horseback. One by one, they loaded the villagers up into cages and carried them off without any explanation... I barely managed to escape alive. (Source: Star Fruit Books)
