Crayon Shinchan Kasugabe Sign-In System

12-Year-old Guo Jialiang never thought that an accident would allow him to travel to the world of Crayon Shin-chan and become Mei Ya's younger brother and Xiao Xin's uncle. What's even more bizarre is that he is bound to a "Kasukabe Daily Check-in System" - you can receive rewards every day you open your eyes, from "a remote control that makes Xiaoxin quiet in seconds" to "the same anti-stress physique as Guangzhi", and even "mind-reading skills that can see through Xiao Ai's little thoughts." As the youngest temporary teaching assistant in Futaba Kindergarten, he used system rewards to cope with Xiaoxin's "elephant dance" and Nini's "super-realistic pretending to be a family wine", helped Guangzhi pay off the mortgage, and accompanied Miya to grab supermarket specials. At the same time, in his busy daily life, he bumped into Ai, a transfer student. At first, the eldest lady who called "Heiji" only regarded him as an "interesting commoner", but after getting along with him again and again, she was moved by the roses he exchanged for signing in, the "disguised green peppers" with hidden strawberry flavor, and his reliable protection at critical moments. From being forced to be her "exclusive instructor" to accompanying her against the "fiancé" arranged by her family, Ryo not only gained the affection of the Nohara family in this world full of fireworks, but also let the arrogant young lady quietly live in the heart of a young man who can complain but always protects her. When the ultimate reward of the sign-in system pointed to "staying with the one you love", Liang looked at the smiling little Ai beside him, and suddenly understood: traveling here may not only be luck, but also the gentle bond of destiny. This is a story about a 12-year-old boy who uses sign-in rewards to have fun in the world of Crayon Shin-chan, and finally marries the eldest lady home.
