Takeru's grandfather is an unnamed character in the Yu-Gi-Oh! VRAINS anime.
After his grandson, Takeru Homura was rescued from the Lost Incident, he visited him in the hospital with his wife. They were hesitant to answer when Takeru asked where his parents were. After he recovered, the couple took Takeru to their home, informing him that he'd be staying there from now on. They tearfully revealed that during the Lost Incident, Takeru's parents had relentlessly searched for him, but were in an accident that resulted in their deaths.
