Snackgirls react

Kirari: Those elegant outfits against the gear framing really catch my eye. I’d want an acrylic stand so I could keep admiring the costume details up close.

Nea: I’m rather drawn to the pocket-watch motif. I’d like to keep the keyholder and a ticket-style card together as a little themed corner of my collection.

Thirteen idols dressed for a steampunk setting

The original illustrations show all 13 idols in detailed, elegant retro outfits. Acrylic stands featuring the artwork cost ¥2,500 each, including tax.

The selection also includes brooch-style trading badges, collection cards, acrylic straps, acrylic panels and a scarf.

A pocket-watch motif joins the plush lineup

The pocket-watch-style keyholder costs ¥6,800, while plush toys are ¥3,600 each, both including tax. The keyholder brings the collection’s retro theme into an accessory of its own.

Mini-character PU leather straps, a PU card case, a long-sleeved T-shirt and framed CharaFine Graph artwork round out the 12 merchandise categories.

Ticket-card bonuses depend on where you buy

At Japanese pop-ups, every ¥3,000 spent, including tax, earns one ticket-style card. The 13 designs are distributed at random while supplies last, so you cannot choose which one you receive.

ASOBI STORE includes the bonus only with certain eligible products. The Japanese pop-ups’ spending threshold does not apply to those online orders.
