Weiss Schwarz S.B Shinmai Maou no Testament Mio Sst/W62-051SP Signed KADOKAWA

This listing offers a Weiss Schwarz signed special card featuring Mio from Shinmai Maou no Testament (The Testament of Sister New Devil), published by KADOKAWA. Weiss Schwarz is a competitive and collectible trading card game produced by Bushiroad, and cards bearing authentic signatures from voice actors or production staff are among the most sought-after pulls in any set. For fans of the series and Weiss Schwarz collectors alike, a signed SP — or Special card — represents one of the rarest and most personal additions a collection can hold.

The card in question is catalogue number Sst/W62-051SP, drawn from the Shinmai Maou no Testament Weiss Schwarz set, published in association with KADOKAWA. The character featured is Mio, one of the central figures of the franchise, and the SP designation indicates this is a foil special-rarity card variant. The signature present on the card is noted in the title as an authentic signed copy, making it a step above a standard SP pull. This item is listed under the Bushiroad vendor, consistent with Bushiroad's role as the manufacturer and distributor of the Weiss Schwarz card game.

Shinmai Maou no Testament began as a light novel series published under KADOKAWA's Kadokawa Sneaker Bunko imprint before receiving anime adaptations that expanded its fanbase considerably. Within Weiss Schwarz, sets tied to popular light novel and anime properties from KADOKAWA have historically attracted strong collector interest, particularly for their signed card variants, which are inserted at extremely low rates into booster packaging. Acquiring a signed SP outside of pack opening — through the pre-owned Japanese market — is often the most practical route for collectors who want to add a specific signed card to their collection without committing to large booster purchases. Pre-owned cards sourced from Japan benefit from the country's well-established collector culture, where cards are typically handled with care and stored properly from the point of acquisition.

This is a pre-owned item that has been sourced from the Japanese secondary market. It has been reviewed prior to listing and is represented honestly based on its observed condition. As with any pre-owned collectible of this nature, the card or any accompanying original packaging may show signs of prior ownership or age-appropriate wear. No claims of sealed, mint, or factory-fresh condition are made unless explicitly stated elsewhere in the listing. Buyers are encouraged to review all available photographs before completing a purchase, and any questions about condition are welcome prior to checkout.

A signed Weiss Schwarz SP card like this one makes a genuinely striking display piece for any dedicated fan or player. Whether sleeved and placed in a binder alongside a complete set, framed under UV-protective material, or displayed in a premium card case, the combination of the SP foil treatment and an authentic signature gives this card a visual and sentimental weight that standard cards simply cannot match. For collectors who follow Mio as a character or who appreciate the craftsmanship that goes into Weiss Schwarz's higher-rarity card illustrations, this is the kind of piece that anchors a collection and rarely becomes available again once it finds a permanent home.
