* Based on a fantasy romantic adventure manga by Maybe.

After gathering the rings and challenging the Lord of the Abyss to a conclusive battle, Satou, Hime, and the others were able to corner their opponent and were only one step away from triumph. But Satou was so exhausted that he found himself in a perilous situation. The group was able to temporarily reassemble after Arabasta saved them at the last second. At that moment, Morion, Hime's younger sister, emerged out of nowhere. Satou and the princesses decided to go through training to bolster their abilities and fortify their ties in order to fight the Lord of the Abyss again; this program is called the "Bride's Trial." Through a series of hardships, Satou and Hime's bond deepened, while his relationships with Nefritis, Granart, Saphir, and Amber also strengthened. Will Satou and his friends be able to overcome the Lord of the Abyss and bring peace back this time? This otherworldly newlywed dream is set to resurrect the "Bride's Trial"—a mission that could decide the fate of the entire globe!
