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".

His pussyfoot maneuver was stated by Oda as being as fast as Soru, but Kuro doesn't know where he's going throughout the duration of the technique.

Oda gave Law such a cool looking devil fruit ability with his epithet being "Surgeon of death", and his appearance. It was such a perfect mix of traits to make a great character all around!
