†Ayase Kamiyugi†, Angel Killer/Trivia

• This card depicts Ayase Kamiyugi, a character from the Z/X -Zillions of enemy X- TCG.
  • In February 2016, a questionnaire was published asking players which characters they would like to see in a collaboration. Tama was the most voted-for character on the WIXOSS side, resulting in the creation of the Z/X card Tama, Skyfire Miko. Ayase was the most voted-for character on the Z/X side, resulting in the creation of this card.
  • This card's art also depicts Sieger, Ayase's Z/X partner.
  • Ironically, while this card depicts a human that hates angels, its class is Idle Spirit: Angel. However, there is at least one timeline in the Z/X story where Ayase becomes an angel.
• This card's first ability is based on the card Fallen Angel Killer from Z/X TCG with additional discard cost. The second ability is a direct reference to Ayase's moniker as "Angel Killer". While the third ability alludes to Black card's ability in Z/X to outright destroy the opposing card.
• This card is the only SIGNI in the game that breaks the regular naming convention for its class. The Angel SIGNI naming convention is usually a kanji phrase, then the particle の, then another kanji phrase, then a katakana name.
• This card shares several similarities with Code Art †ALCA†. They are both black SIGNI in a class that is not normally black that serve to preview the presence of black-shifted SIGNI in the next booster pack (Code Art †ALCA† came before the appearance of black Electronics SIGNI in WX-12 Replied Selector, while this card came before the appearance of black Angel SIGNI in WX-14 Succeed Selector). They are also both promotional collaboration cards, featuring characters from other franchises.
