Gu Chen thought his life was a sweet and romantic comedy, a reincarnation into a crossover anime world. On his left was the perfect maid who raised him, on his right was his proud and cute blonde childhood friend, and in front of him was his sharp-tongued and charming senior with long, straight black hair. Life should have been this perfect.

Until his fifteenth birthday, he tore away the veneer of world peace. Fishermen with gills growing on the beach, mad ramblings echoing from the old school building—beneath the surface of daily life lies a profound malice capable of tearing the entire world apart.

It was on that day that he awakened a god-level talent called [Five Senses Connection], which allowed him to share his senses with the proud women of another world.

Through the eyes of a certain electric-shocking princess, he glimpsed the limits of science; through the taste buds of a certain god-obsessed queen, he savored the flavors of the gods; through the ears of a certain useless goddess, he heard the complaints of the heavens…

When Gu Chen discovered that he could not only see through all worlds, but also quietly bring the forgotten, out-of-control servant civilization legacy on Earth—that silent, uninhabited starport—to various worlds through the bodies and wills of the girls, he made a decision.

"Eri, stop drawing doujinshi. I'll teach you how to pilot a mecha and fight for love and peace."

"Senior Shiyu, stop working on new books. Reality is more absurd than fiction. You'll be the one to write this 'Investigation Report on the Descent of the Old Days'."

When daily life crumbles and lovers are in danger, Gu Chen will use the iron and fire of the starry sea to play the final symphony of protection for everything he cherishes.
