The old lady is a character in Yu-Gi-Oh! 5D's, who purchased a quantity of Oshiruko Noodles.
Outside the R.A. Market, she was robbed by a man on his Duel Runner, who snatched her shopping cart full of Oshiruko Noodles. However, Lazar fired a rope at him, locking it around his wrist and pulled him him off the Duel Runner. Lazar proceeded to steal the Oshiruko Noodles from him. The lady mistook the event as Lazar trying to get the food back for her. She took back the noodles, thanked him and gave him one of the five cup noodles as a reward. However, Lazar grabbed two more and ran off, leaving the lady stunned.
