Card Trivia:Protective Soul Ailin
- This card is based on Ailin Kurashima, the son of former UDE Product Manager Leighton Kurashima, who passed away hours after birth. The card "Indomitable Fighter Lei Lei", which it equips to, is based on Leighton, as his nickname is "Lei Lei".
- This card features similarities with "Second Goblin", as both cards are Union monsters that can be equipped to specific monsters ("Giant Orc" for "Second Goblin", and "Indomitable Fighter Lei Lei" for this card), both of which features identical effects.
