PLAMATEA VALKYRIE TUNE Erika = Stradivari Plastic Model is a non-scale bishojo kit from Good Smile Company in the VALKYRIE TUNE line. Standing about 160 mm tall, the model features color-separated runners and pre-painted parts for straightforward assembly. Four interchangeable face plates provide multiple expressions, plus four blank faces with decals for customization. Translucent blue parts accent the main body and weapons, while the Harmonic Weapon— a violin-type instrument— can transform into a Bowgun and, if reassembled, into a large blade. Frills on the skirt and arms are removable; an articulated stand and interchangeable hands support dynamic poses, and parts can be rearranged to display high-speed light equipment mode.

Erika = Stradivari is depicted as a serious and stoic strategist within the VALKYRIE TUNE universe. As a member of the Valkyrie team, she wields the Harmonic Weapon, a violin that channels musical energy into combat. Her demeanor reflects discipline, precision, and unwavering focus, guiding her allies through challenging missions. The character's backstory emphasizes duty, loyalty, and a calm, almost austere confidence under pressure. Her weapon transformations—from Instrument Mode to Bowgun and then to a large blade—symbolize adaptive tactics in battle. This plastic model captures Erika's elegant silhouette and controlled elegance, highlighting the contrast between delicate artistry and formidable battlefield prowess.
