Designed in a compact, dynamic duo style, Mascot Character Puugeru-kun and Sonia-chan captures a lively moment of transformation. Puugeru-kun, the mischievous mascot, perches cheerfully on Sonia-chan's gloved hand, his oversized head and perky ears emphasized by glossy paint and subtle shading. Sonia-chan stands with a confident pose, her cape fluttering and her eyes wide with determination. The two figures are coordinated in color—soft pastel tones with bright accent hues—and each piece is finished with delicate texture, from fabric-like sculpting to the translucent effect at the transformation corners. The pedestal base ties the composition together with a glossy sunburst motif.

In the Mascot Character world, Puugeru-kun is a sprightly companion spirit who helps heroes discover their courage. Sonia-chan, a cheerful tactician with a soft voice and a sharp mind, acts as Puugeru-kun's partner in playful adventures across dimensional fairs and city rooftops. When danger begins to simmer, Sonia-chan calls out henshin—an energetic shout that awakens Puugeru-kun's hidden power and reveals a luminous transformation motif that glows through their costumes and base. Together they navigate quests where friendship, kindness, and quick thinking triumph over mischief. The duo's lighthearted teamwork teaches younger collectors that even small figures can spark big imagination.
