- This is the first member of the "Utopia" archetype to not have 39 as its number, instead being 39 reversed.
- This card is the first Rank 12 monster to be released in the OCG/TCG.
- This card's Summoning condition is similar to "Number F0: Utopic Future" and "Number S0: Utopic ZEXAL". All three monsters can only be Xyz Summoned by using Xyz Monsters with the same Rank.
- Strangely, and unlike "Number F0" and "Number S0", this card does not obey the rule that all Xyz Monsters must have a Rank equal to the Levels of their usual Xyz Materials. All three monsters mentioned use Xyz Materials that lack Levels entirely, thus "Number F0" and "Number S0" have a Rank of 0, but this card uniquely has a Rank of 12 while never using or mentioning Level 12 monsters at all in its Summoning condition.
- This card's OCG/TCG artwork is taken from Yu-Gi-Oh! ZEXAL Rank 54: "The True King of Numbers!!", specifically from the panel showing this monster being Summoned.
- This monster appears in the artwork of "Commitment to Tomorrow".
