Shia Kijima キジマ・シア
Little sister of Kijima Wilfrid, and a regular fighter in the Gunpla Academy team. Shia appears to understand Gunpla and their feelings despite them being inanimate, allowing her to easily repair them and tweak them to their maximum capabilities. She also appears to be a superior Gunpla builder than Yuuma Kousaka and Minato Sakai.
