Ryu Granger (木ノ宮 龍之介, Kinomiya Ryuunosuke) is Tyson's Grandpa.
Personality & Characteristics
The elder Granger is an enthusiastic and energetic character, although more civilized in the Japanese version of the anime (in the English dub, he is the "cool-yo" type). He sometimes follows the team around the world to support them during tournaments. In Japan, he also offers a home for the team.
In general, he mostly creates comic relief, but he also occasionally (and involuntarily) makes Tyson realize some important tips for Beyblading, such as the winder lengthening trick.
He welcomed his grandson to his dojo when Yoshie Kinomiya died since his son, Tatsuya, was traveling and couldn't take care of Tyson. He practices swordsmanship, kendo actually, and tries in vain to teach Tyson some tricks, but the latter has other interests.
For family reasons, Ryu's dojo also housed the sword-shaped stone inside which Dragoon was trapped.
In G-Revolution, he took the place of the fifth member on Tyson's G Revolution team as "Mr. X". This was only temporary, because Tyson was looking for the appropriate Beyblader to complete his team and Kai was nowhere to be seen, yet the Justice 5 tournament rules required for him to submit a list of 5 players before a certain deadline.
