Details on the “The Wizard of Mongarta” POP-UP SHOP

A POP-UP SHOP for the Cthulhu Mythos TRPG scenario “The Wizard of Mongarta” by Mr. Sanmiya will be held at MEDICOS SHOP Shinjuku on the 2nd floor of Shinjuku Marui Annex.

Newly drawn illustrations themed around a “Tea Party” have been created specifically for this event. At the venue, new merchandise featuring these illustrations will be on sale, and bonus mini-cards (6 varieties total) will be distributed. Additionally, an oversized panel of Fika Karel Hezerich, also featuring the same illustration, will be on display.

New products featuring original illustrations are here!

At the event, a total of 10 items will be on sale, focusing on merchandise featuring new, original illustrations based on the “Tea Party” theme.

BIG acrylic stands and acrylic dioramas are here!

There are 6 types of “BIG Acrylic Stands” that let you fully enjoy the full-body, newly drawn illustrations. Each comes with a base in a color unique to that character. The “Acrylic Dioramas” allow you to display the 6 characters from the newly drawn illustrations alongside background pieces featuring “Mangata Magic Academy.”

Also available are the “Dialogue Acrylic Keychains” (6 varieties total), featuring secret artwork designs, and “Black Tea” (limited quantity) in a container adorned with the “Mangata Magic Academy” school crest!

Random merchandise, such as pin badges, is also available!

The random merchandise consists of six items: the “Pin Badge Collection,” “Acrylic Keychain Collection,” “Acrylic Block Collection,” “Mini Photo Card Collection,” “Student ID-Style Clear Card Collection,” and “Acrylic Name Badge Collection.”

Each collection features six blind-pack varieties with all-new illustrations; as long as the box remains unopened, you can collect all varieties within a single box.

Product Lineup & Purchase Limits

The purchase limit is up to 5 items per type per person per transaction (up to 5 BOXes per type). For random items, you may purchase up to 5 BOXes per type if they are sold as BOXes, or up to 5 units per type if sold individually. These limits may be changed or lifted depending on sales conditions.

Receive a bonus mini card (6 varieties total) as a gift

During the campaign period, for every 1,000 yen (tax included) spent on “The Wizard of Mongarta” merchandise, you’ll receive one random bonus mini card (6 varieties total) featuring an original illustration. You cannot choose the design, and this offer ends when supplies run out.

[Event-Exclusive] Oversized Panel Giveaway Campaign

A campaign will also be held where a total of three winners will be selected by lottery to receive oversized panels (3 types in total) featuring original illustrations displayed at the venue. The giveaway is limited to the three figures of Fika, Karel, and Hezerich, and participants can choose their character when entering.

To participate, you will receive one entry ticket for every 5,000 yen (tax included) spent on “The Wizard of Mongarta” merchandise at the venue during the campaign period. For example, a total purchase of 15,000 yen (tax included) will earn you three entry tickets; however, receipts cannot be combined. The entry period runs from October 31, 2026, until 11:59 PM on November 12.

Winners will be notified via shipment of their prizes. As these are exhibition items, they may have scratches, dents, or stains; entry is limited to residents of Japan. Since this is a venue-exclusive campaign, merchandise purchased online after the event is not eligible.

Post-event online sales will begin at noon on November 13

Items sold at the POP UP SHOP will be available for post-event online purchase at the MEDICOS ONLINE SHOP from noon on November 13, 2026, through December 1. A bonus mini-card will also be included with post-event online orders.

Random items are sold only in boxes; individual items are not available. One box contains all varieties. Post-event online sales are limited-quantity, made-to-order, and not first-come, first-served; all items reserved during the order period will be delivered.

Shuffle Lottery Admission on October 31

On the first day, October 31, 2026, a shuffle lottery admission system will be implemented to alleviate crowding. Numbered tickets will be distributed in front of MEDICOS SHOP Shinjuku from 10:30 to 10:40, and the admission order will be announced around 11:00 on X “MEDICOS Entertainment_General.” The first admission slot will begin at 11:15.

Since admission is not on a first-come, first-served basis, there is no advantage to lining up before the numbered ticket distribution time. Each numbered ticket allows for one entry and one transaction; once all customers with numbered tickets have entered, admission will be open to the general public. Admission may be limited on days other than the designated dates as well.

Please note that visitors are asked to refrain from coming to the store in cosplay or attire that could be perceived as cosplay. MEDICOS SHOP Shinjuku is open weekdays from 11:00 AM to 8:00 PM, and weekends and holidays from 10:30 AM to 8:00 PM. Please check the official website and official X account for the latest information before visiting.
