Dan comes out as a mature, but arrogant person. He is very patient and waits for the opponent to attack first. He seems to always tell Reiki when and how to do things and this may sometimes upset Reiki. His arrogance is shown when Saggitario continued to spin and he said to Reiki, "This is all because someone wasn't paying attention..." Dan continued to blame Reiki for this and he then said, "My strategy was absolutely perfect, bro." He even calls his brother 'unskilled'. Also Dan is very harsh when he says "No buts, I'm the one who decides." Dan is seen to be a better blader because if Reiki wasn't so hasty, they could have won the battle.
Beyblade: Metal Fusion
Dan and his twin brother Reiki are Dark Nebula's grunts, who specialize in combination moves. They are first sent to stop Gingka and Kyoya from getting to Doji, when they break into the headquarters. Using their combo attacks they manage to toss Leone around the place. However Kyoya realizes their beys have nothing special abouth them and decides to end the battle with his special move. Dan boasts about Kyoya's special move relying on the wind but is shocked to see Kyoya use his special move by generating his own air currentsends up defeated.
The brothers then train hard to get stronger and it is a result of their intense training and spirit that Doji gives them a new bey, Evil Gemios, a bey which would allow them to combine both their powers in one bey. They are then sent to participate in the 10,000 bey-point tournament along with Yu and Tsubasa. With a new look, they step forward to battle Kenta. Dan being the defensive blader, blocks Kenta's attacks while Reiki counter-attacks. Being the smarter of the two, Dan is the one who orders Reiki around and makes the plans for the duo. However Reiki's hasty personality causes him to abandon Dan's plan of waiting and attacking. The arrogant Dan takes no time in insulting Reiki, which causes a conflict between the twins, giving Kenta all the time he needs to recover from his weakness and pull out a special move that defeats Gemios.
Dan and Reiki are suumoned to fight the traitor Tsubasa. Honored by the opportunity, the twins give it their all attacking, only missing and knocking their fellow bladers out. Tsubasa then manages to take them out.
They are somehow able to earn 50,000 points and thus battle Tsubasa again in the Battle Bladers, however once again they are defeated, giving Dan another reason to insult his brother. They are then made to battle Ryuga for their loss. They are knocked out cold and their spirits devoured by L-Drago. Their spirits return to them after L-Drago's beaten and they celebrate Gingka's victory with everyone else.

- He along with Reiki resemble Patrick Sprigs  from Mega Man Star Force as they have light colored hair, similar outfits, and are associated with the constellation Gemini.
