I recently bought these two promo figures of Kyoko from Zombicide Season 1. The pack contained Survivor and Zombivor versions of her.
Kyoko was originally offered as a prize for those who designed scenarios for Zombicide Season 1. The prize winning scenarios are available online in the Guillotine Games website and in the Zombicide Compendium book Volume 1. Kyoko became the official mascot for this book. I saw that someone was offering her for sale on eBay and made a bid for her. My bid was accepted and she cost me £12.00, which is a lot of money to pay for two plastic 28mm scale figures but given her rarity and the fact that Season 1 Zombicide figures often sell for £30+ I think I got a bargain. She is the only Season 1 promo figure I own, so she has pride of place in my collection.
