Caroline Yajima is a wealthy girl whose father, Shoji Yajima, runs a major business conglomerate. She's best known for her intense rivalry with China, stemming from years of losing to her at local art competitions. When Caroline found out China had taken up Gunpla building, she decided to get involved too—but on her own terms. Rather than compete directly at established tournaments, she organized her own all-girl Gunpla Battle event specifically to challenge China.
The turning point came when her father's company became a sponsor for Nils Kczęść. Caroline leveraged that connection to have Nils build a custom Gunpla for her to use in battle. It's a pretty straightforward move that shows just how far she's willing to go to finally beat China at something.
