- The object attached to the chain is not a kunai. Real life kunai are Japanese digging tools, similar to a trowel, that ninjas used primarily as stabbing weapons (though they can be thrown like a shuriken). They can be combined with a length of chain or rope to form a weapon known as a rope dart (which is used similarly to a chain whip in Chinese martial arts), but the object on the card more closely resembles a kusarigama.
- Additionally, despite its OCG name being "Chain-Attached Boomerang", the object itself barely resembles one.
- In Yu-Gi-Oh! The Duelists of the Roses, Yu-Gi-Oh! The Sacred Cards, Yu-Gi-Oh! Reshef of Destruction and Yu-Gi-Oh! BAM, this card is a Spell Card.
