Crayon Shin-chan: Kasukabe Sign-In System

Guo Jialiang, twelve years old, never imagined that an accident would send him to the world of Crayon Shin-chan, where he would become Misae's younger brother and Shin-chan's uncle. Even stranger, he was bound to a Kasukabe Daily Sign-In System. Every morning, he could claim a reward just by opening his eyes, from a remote control that instantly quiets Shin-chan to Hiroshi's famously stress-resistant constitution, and even mind-reading powers that could see through Ai's little schemes.

As the youngest temporary teaching assistant at Futaba Kindergarten, he uses his System rewards to deal with Shin-chan's elephant dance and Nene's ultra-realistic pretend games, helps Hiroshi pay the mortgage, and accompanies Misae on her supermarket bargain hunts. Amid the chaos of everyday life, he also runs right into the newly transferred Ai Suotome.

At first, the young lady who calls out for Kuroiso sees him as nothing more than an interesting commoner. But as they spend more time together, she's won over by the roses he gets through sign-in rewards, the strawberry-flavored fake bell peppers, and the reliable way he protects her when it matters. From being forced to act as her personal tutor to helping her stand up to the fiance her family has chosen for her, Liang finds not only the warmth of the Nohara family in this lively world, but also a place in the heart of a haughty young lady. A boy who loves to tease her, yet is always there to protect her, quietly takes up residence in her heart.

When the Sign-In System's ultimate reward points to spending a lifetime with the one he loves, Liang looks at Ai, smiling brightly beside him, and suddenly understands: perhaps coming to this world wasn't just luck, but a tender bond written in the stars. This is the story of a twelve-year-old boy who uses sign-in rewards to make the most of everyday life in the world of Crayon Shin-chan, and ultimately brings the young lady home as his bride.
