Saber Marionette J

Overview

Marionettes are modeled after women in every way, but to fall in love with them is taboo. So what is poor boy Otaru Mamiya to do when he develops a massive crush on a Marionette named Lime, a unique Saber model with a special circuit that gives her emotions? When Otaru awakens two more mysterious Saber Marionettes, his life as an average man quickly becomes as extraordinary as the circuitry under the flesh of his busty new friends. (Source: VIZ Media)
