It is the dawn of another new day. A new Star Fragment, has entered the Earth's atmosphere. Yuki, a young astronomer and a Blader, is keen to see the mysteries behind the Star Fragment and unlock its secrets.
Yuki had just arrived to his destination by plane to study the Star Fragment. However, he is stopped by none other than Johannes. Johannes challenges him to a battle and they proceed. Yuki's Anubius fights against Johannes's Beat Lynx.
In Pluto's lair in Mexico, the powers of the beys of some of the Legendary Bladers are used to begin the revival of Nemesis. The energy that this process emits alerts Gingka and his friends to the impending danger and they decide to head to Mexico to stop the revival before it's too late. Meanwhile Ryuga feels the power of Nemesis' revival too and plans to take the power for himself.
Gingka and his friends have landed in Mexico and rush to try and stop Nemesis' Revival. Inside the temple, Rago, the Child of the Black Son, has already arrived. Gingka, King, Yuki, Masaune and Madoka make it inside the temple and battles begin.
Gingka defeats Chris in battle but convinces Chris that as a Legendary Blader, Chris is part of a team and not alone anymore. Aguma is defeated by Tithi and Dynamis gets Aguma to go with him and follow Gingka and the others. Gingka arrives at the Temple of Nemesis where he meets up with Pluto, Rago and to his surprise, Doji.
In a temple in Mexico, Rago battles all comers including Gingka and his friends and Ryuga and none of their beys have any effect on Rago's Diablo Nemesis as it sends them all flying Pegasus. Before Gingka and the others can decide on their next move, Rago uses the power of Diablo Nemesis to destroy the temple.
While the WBBA and all its members are searching the world for signs of Rago and Nemesis, Gingka and his friends are training hard for the battle they know is ahead of them. Meanwhile, Rago, Doji and Pluto are on a boat in the middle of the ocean, attempting to raise the sunken Kingdom of King Hades.
Gingka and his friends try to help Ryuga who has been badly hurt in a battle with Rago, but it appears they are too late to save him. With Ryuga gone, Dynamis tells them that it means that Zeus barrier cannot be completed and now they cannot depend on any help from Mother Earth, they are on their own.
Gingka and the rest of the Four Season Legendary Bladers appear to complete Zeus' Barrier and seal Nemesis away for good, along with Rago and Pluto who are carried down with the destruction of the Lost Kingdom of Hades. Their celebration is short lived though as through a crack in Zeus' Barrier, the God of Destruction appears and is determined to destroy the earth.
Gingka and his friends fly towards the location of Nemesis in the Pacific Ocean, but the helicopter they are travelling in hits a vicious storm. They are forced to land on a deserted island and use boats to get to the Lost Kingdom of King Hades where they believe Nemesis is located.
Kenta and his newly evolved bey, Flash Sagittario, battle head to head with Rago and his bey, Diablo Nemesis. Gingka is convinced that Kenta has been given the powers of the summer constellation legendary Blader from Ryuga. The others agree and a new attempt to create the Barrier of Zeus begins as they try to seal up the God of Destruction.
