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.

One day, the protagonist wakes up in the body of Charlotte, a gentle healer living in a world of magic and nobility. Her new life seems peaceful, until she discovers that Charlotte had just accepted a suspicious commission: to create a love potion.

The problem? Charlotte isn't a witch, just a misunderstood herbalist mistaken for one. And before she can figure out who requested the potion, the Crown Prince himself shows up at her door.

Convinced he's the mysterious client, Charlotte panics. If she refuses now, she might lose her head for disobedience! So she decides to fake it till she makes it, brewing potions by instinct and stumbling into one awkward royal encounter after another. But the more she tries to survive, the more tangled her fate becomes with his.

"Wait... isn't this one of those classic romance clichés?" 

Apparently, it's now her life.

The Hero's Reunion

再会の勇者

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.
