The Truth About Light and Darkness (光と闇の真実 Hikari to Yami no Shinjitsu) is the 48th episode of Beyblade: Metal Fusion. It aired March 7, 2010 in Japan and on February 19, 2011 in the United States.
As the shards fall down, they break Phoenix's mask which reveals that Phoenix is in fact, Gingka's own father, Ryo Hagane. Gingka bursts into tears and asks him how could he be alive and not come right away. He runs into his father and hugs him while Ryo tells him that he's sorry. Ryo tells them that they need to rescue Yu right away. The gang go to a Dark Nebula cell, where Bladers who are to be drained of their energy and given to Ryuga like Dan and Reiki, Tobio, and Tetsuya are kept. Yu hears them comes and they rescue him. Meanwhile in Battle Bladers, Blader DJ announces that Gingka has made it into the finals. However it is unknown who he will face, Kyoya or Ryuga. As Benkei watches some of Ryuga's battles, Kyoya tells him to turn it off as he's seen enough and tells Benkei to follow him. When the gang sit down to take a break, Gingka asks Ryo why he didn't tell him that he was alive. Ryo decides it's time to tell them the story of the history of Beyblade. Long ago, meteorites fell down on Earth. Hyoma recalls this, as one meteorite made his favourite Green Hades arena. However there were much more, and one had filled itself with Dark Power. The ancient people of that time, used that power for the basis of L-Drago. With that power, they were able to control the world of war. As with the hatred and anger of the army's servants it turned into dark power and was able to make L-Drago very powerful. Over time, in the battles it fought, it's power and shape differed to make the L-Drago people know today. It also has been passed down from generation to generation. However others made a Bey to represent the light of hope, and would become the basis of Beyblades today - Pegasus. Pegasus was barely able to defeat L-Drago. Due to the immense power of L-Drago the people of Koma Village had locked away for all eternity and it would become known as the "Forbidden Bey". However, there were still people who wanted to control that power, Dark Nebula. When they invaded Koma Village in search of it, Ryo tried to stop Ryuga from controlling that power. He failed and Ryuga took L-Drago with him, making the world in danger. At this moment, Ryo looked like he was going to die and gave Gingka his Storm Pegasus and made an exit for him to leave in. However, Hokuto rescued Ryo and got him out safely. Since Ryo had scars he though it would be better if he would stay for a little until he recovers. When Gingka got sidetracked to Koma Village, Ryo was recovered. When he saw how Gingka fought with the bond of his friends he knew he had to put on a disguise in order to see how Gingka was doing and thus, Phoenix was born. He revealed that he was watching Gingka in Battle Bladers from the shadows and would help in his time of need or to become an obstacle. Ryo tells Gingka that in the end, the final battle with Ryuga, the bond of Gingka and his friends in his journey will help him to defeat Ryuga and L-Drago. Gingka realizes what his father did to protect him and thanks him for that. On the other hand, Kyoya dismisses all this power of friendship and tells Gingka that he will face not Ryuga, but him, Kyoya in the final battles. Kyoya states that Gingka's not the only one who's been through tough challenges and this whole journey Kyoya made was so that he would be able to defeat Gingka once and for all. Gingka acknowledges this and tells him that he's ready to fight Kyoya whenever the time comes. Doji gets out of the crystal trap he was in and limps away. He says that he will never forgive Phoenix but just then, Ryuga comes. At first Doji is happy at this but Ryuga has other plans. He tells Doji why he would need more power to defeat Gingka if he already has Lightning L-Drago. Doji just says it was backup just in case. Ryuga ignores this and tells him that if he needs more power he should take Doji's power. Doji gets surprised at this and won't let this happen. He launches his Dark Wolf at Ryuga's L-Drago but quickly loses. L-Drago sucks all the energy out of Doji leaving Doji powerless. Ryuga leaves while Doji just stays lying on the ground. Ryuga says that once he beats Kyoya he will have power to crush Gingka.
