While Riki was anxiously waiting his first Cross Fight call his mother comes in to give him his lunch but is quickly kicked out by Riki confusing her.
She is then also seen walking into Riki's room several episodes later, telling him to go down or his dinner would be cold. After hearing her son saying that he will be down soon, Mrs. Ryugasaki closed the door and voices out her worries about Dracyan.
And in the final episode of B-Daman Crossfire, she could be seen at Riki's home looking at what's persumably Riki's laptop screen, showing a live battle between Riki and Samuru against Rudy and Dragold. After the battle ended she gives a thumbs up and says, "Good job Riki!"
