In the deadly battle at the Watergate City of Priestella, Subaru and his allies barely emerged victorious—but their triumph came at a great cost. Through the "Authority of Gluttony," Rem was put into suspended animation, while Crusch's memories and even Julius’s name were devoured. As he searches for a way to save them, Subaru learns of the "wise man" Shaula—an all-seeing being said to possess every form of knowledge. His next destination is the Pleiades Watchtower, home to a wise man, the farthest tower standing in the vast, uncharted desert known as the Auguria Dunes—a place so perilous that even the mightiest "Sword Saint," Reinhard, failed to conquer it. The fury of nature, unknown magical beasts, and unimaginable dangers lie ahead. Together with his friends, Subaru embarks on a life-risking journey to reclaim what was lost.

Confessing to my childhood friend Marika was impossible for someone as unpopular as me. So, I did what any desperate boy would do—I wished upon a shooting star! When I woke up, that dream had come true?! I could see a love meter for people, just like in a love simulation game. Once I realized this was real and not a dream I went straight to see Marika. Her love meter was so low it had broken and practically fallen all the way to hell! If she hated me so much why was she so nice?! Is this how she really felt or...?!
