Card Trivia:Girsu, the Orcust Mekk-Knight
- This monster appears in the artwork of "Vesper Girsu". One of its hands can also be seen in that of "World Legacy Token".
- Conversely, "World Legacy Token" appears in this card's artwork.
- This card's effect of Summoning a "World Legacy Token" and treating itself as a Tuner is a reference to the bond between "Ningirsu the World Chalice Warrior" and "Ib the World Chalice Priestess", as this card's effect supports the Synchro Summon of this monster's sister, "Ib the World Chalice Justiciar".
- Also, the orange ribbon this monster is holding is the same as that of "Crowned by the World Chalice".
- "Beckoned by the World Chalice" → "Ningirsu the World Chalice Warrior" → "Longirsu, the Orcust Orchestrator" → "Dingirsu, the Orcust of the Evening Star" → "Girsu, the Orcust Mekk-Knight"
- This monster is "Longirsu, the Orcust Orchestrator" after it was revived by "Avida, Rebuilder of Worlds" as the last "Mekk-Knight" in order to protect the Earth, along with the soul of "Galatea, the Orcust Automaton" (now "World Legacy Token").
- This monster's appearance is based on "Dingirsu, the Orcust of the Evening Star".
- This monster can be considered another counterpart of "Mekk-Knight of the Morning Star", along with "Dingirsu".
- The kanji 「宵星の騎士」 (Shōsei no Kishi, "Knight of the Evening Star") in this card's Japanese name is derived from the kanji 「宵星の機神」 (Shōsei no Kikaishin, "Machine God of the Evening Star") in the Japanese name of "Dingirsu, the Orcust of the Evening Star".
