Chained Soldier, Vol. 1 By: Takahiro Takahiro, Yohei Takemura, Christine Dashiell

Otherworldly spaces known as "demon cities" appeared in various parts of Japan, and
those who partook in the "peaches" growing there gained unique abilities-but only if
they're girls. One day, a down-in-the-dumps high school boy named Yuuki Wagura
suddenly gets lost at the entrance of a demon city. There, he meets Kyoka Uzen, the
beautiful leader of the seven programs of "Magical Defense Corps," whoo orders him to
become her slave?!
