Robou is a corporate drone with an extraordinary passion for giant humanoid robots. One day, he's deeply hurt when a colleague bluntly states, "There's no need for giant humanoid robots." Later that evening, he's approached by a being from another world who pleads with him to "fight using a giant robot." After some hesitation, Robou chooses to reincarnate into this new world. There, he finds himself inhabiting Volcamion—a mighty humanoid mecha revered by the Volcami Empire. Thus begins Robou's second life as a god within a giant robot.

Brothers Without a Tomorrow

To secure an alliance between the northern kingdom of Leracal and the southern realm of Arnata, the countries' royal families agree to a political marriage. Tei, known across the frozen battlefields as the most fearsome warrior and monster hunter, volunteers himself as the kingdom's hostage, trading his life as a warrior for that of a bride. In Arnata, Tei finds not the hostility he anticipated but the calm, steady gaze of Shuraka, the young crown prince destined to become both his spouse and future Padisha of the empire. For Shuraka to claim the throne, however, he must survive an uprising that threatens the kingdom—once that forces him to draw the blood of his own brothers. Moved by the courage and gentle integrity of his betrothed, Tei pledges to protect him at any cost...and in the quiet hours of a white night, two hearts caught between loyalty and longing begin to bloom.

Aka no Nitamame

In a matriarchal world where women dominate and men are treated as lesser beings, Kureto was cast aside at birth for the sin of being born male. He scraped by as an orphan, unwanted and powerless—until the day his unique skill awakened. A "supreme virility" skill that strengthens him with every act shared with a woman.

Under the guise of "training" with his dorm caretaker, Kureto masters his newfound power, achieving strength no man should possess. When he's accepted into the elite Knight Academy—a school meant for noble-born women—he sees a chance to change his fate. To become an honorable knight, to reclaim his dignity, Kureto will fight—both in the arena and between the sheets—against the very women who once looked down on him.
