A reference art has been posted for a yet-unrevealed card from Rush Duel, to be printed in Over Rush Pack 4. The name is アクツキのブラスデス (akutsuki no buradesu). We are using the provisional name of “Brassdes the Akutsuki”, until we learn more about the card. It may be related to other themes, or we may infer something else from the artwork. The name is a multi-layered pun: The most prominent aspect is “akutsuki” being a spin on “噓つき” (usotsuki, liar). The reference art suggests that the monster is “wearing” a demon as a hoodie, so “akutsuki” could be 悪着き(akutsuki, evil + wear). It’s also very close to 暁 (akatsuki、dawn/daybreak) which could just be used by the monster to sound cool. Finally, the t-shirt seems to be a goofy depiction of the demon Asmodeus, which may also be part of the monster’s name. It’s also possible that the “brass” part is closer to “blood”.

As a final TL note, today is April Fools, and in Japan, the date is less about funny pranks and more about telling a lie.
