My Master Is the Postal Princess — Doctor Deicide

"Wendy, will you marry me?"

What is the matter with a lad named Hector_1304, after successfully escaping from the flooded floor and entering the factory floor? What has contributed to his change of heart? Whatever will happen to his mission of climbing Towerld toward the invisibly distant top? Besides, who is a girl named Wendy?

Hector makes a career change from a fisherperson to a mailperson. When Hector tries to deliver a VIP (very important package) to a suite on the floor above, he encounters a berserk forger named Gideon. When he starts the special delivery to the upper floor, he runs into vicious dogs trying to tear outsiders apart, mysterious agents in black suits attempting to confiscate the delivery package, and that nemesis he once avoided on the flooded floor. Will he be able to fend off the obstacles and move on to the next floor?

Hector and Wendy just have to keep on running and climbing, to continue the journey to the upper floors.
