Fictional Cards
Original cards appreared in this fiction are all created from [http://www.yugiohcardmaker.net Yu-Gi-Oh! Card Maker]. Almost characters use both real and fictional cards, however, some characters have their own original card archetypes, particularly Mimura Mizuki (Servitor of Beelzebub Deck). Some of them might be mentioned here as:

Elemental Hero Neos Girl (เอเลเมนทัลฮีโร่ เนออส เกิร์ล)

This card is revealed in the fiction as the winner in Amateur's card design challange test 2009 arranged by Kaiba Corporation. Until this time, it is questionable is whom this card is for (probably Jaden Yuki). The picture is illustrated by a Thai artist E-Hero Neos.

Servitor of Beelzebub - Adirael (ผู้รับใช้ของเบลเซบัฟ เอดิราเอล)

The most famous original card in the fiction and the most important card of Mimura Mizuki also. Adirael is supposed as the rival of Luck Fairy - Sarah Ne (one of rare non-Light Sworn cards in Chuya Ichiwara's deck). Some duelist often use this card in unofficial Yu-Gi-Oh! Tournaments organized in Thailand, especially DARK deck, because of her strong damage effect. The picture is illustrated by E-Hero Neos.
