We start with Bell doing stuff with vials and lab equipment, with different colored liquids. We then see Ranzo and Hannah walking through the Mansion hallways. Ranzo says that Bell might be depressed after losing to Rashad, and Hannah's sad that her brother left for BC Sol. Ranzo says he though Bell would stop Basara. He then giggles and says he can help him if he's sad, but then slips into some goop. Hannah also steps in it. Bell then appears with a big smile, showing that his experiments resulting in a successful prank. Ranzo is annoyed, and Bell says even though he lost to Rashad, he's not really sad, since the Demon King can't get depressed. He then say his usual phrase "It's not a loss, just a preparation for a win." Plus, he has a secret plan. That is the V Gear. It attaches to Venture and can replicate Valkyrie's speed. Ranzo is impressed and wants to check it out, but Bell refuses. Ranzo then asks again (He's in Bell's face but is being polite.) Bell says he's not gonna show it to the enemy before battle. Ranzo gets mad and says he's lucky that "the enemy" is always practicing with him. Bell says that he doesn't even enjoy battling. Hannah tries to get them to calm down. Ranzo says that they're friends, Bell says the Demon King doesn't need any friends, and he doesn't even remember Basara. Ranzo gets mad, saying why would you say that, the reason Basara went to Rashad is because he was being mean like this. Bell just says that he likes to be that type of Demon King. Hannah is sad, and Jingemon looks worried. Ranzo calls him a carp, and says that he's no longer friends. Hannah tries to stop Ranzo but he storms away, and Bell just scoffs,
Later we see Bell as a bridge, holding the bars and looking sadly at the scenery. Then someone comes up to him, saying his name. Bell doesn't know the guy, and he has kids surrounding him. He says that he's Shu. He heard Bell was a Demon King, but now he's getting a different impression. Shu says it looks like he had a fight with a friend. Bell gets mad and says the Demon King doesn't have fights. Shu simply says that he hopes though. He then shows off Astral Spriggan. He says he used to Dynamite System to make the ideal Spriggan, and then challenges Bell to a battle. We cut to Shu and Bell at the mansion, and they agree on a 2 point match. Bell says that it's courageous to fight the Demon King, and then looks back to tell Ranzo to watch, but only his Grandpa Jingemon is there. Jingemon says neither Ranzo or Basara are here, and Bell shouts I know. He says he doesn't care if there isn't anyone here, and then they launch.
Astral Spriggan goes for Belial. Bell realizes that it's a balance type and says he'll show him the horror of the Demon King. The Beys clash and Spriggan easily smashes Belial away. Bell is surprised at how heavy it is. Shu says it can make heavy attacks due to the metal in the layer. Spriggan and Belial clash, and then Belial runs out of stamina. Spriggan says that his disc is the strongest, with it's high centrifugal force. He says Spriggan has no blind spots, even with stamina. Bell is angry, and Shu says he wonder why he got a point. He says that he's not concentrating on the battle, and he couldn't even bring out the Belial's power, let alone win. We see a shot with Shu with Astral Spriggan behind him. He says to show him and Spriggan the best of you (Bell) and Belial. Bell says that Spriggan is an interesting Bey, and he has something to scare him, since he wants to be scared. He says he made it with all his might. We then see Bell and Belial. Bell says he sorry he couldn't get the point, bet he'll go full power this time. Belial says he came make him go full power if he needs too.
They launch, and Belial goes for Spriggan, but Spriggan looks different and is spinning counterclockwise. Spriggan swiftly evades Belial. Bell says it's like a different Bey. Shu says that Astral Sprigan can flip it's layer to spin counterclockwise, and access up to 4 modes with it's tip. Meaning there are 16 possible formations it can use. Shu says it's the ultimate Bey. It attacks Belial, but hits the F Gear, which absorbs the impact. Shu tells Spriggan to push forward, using the move Astral Counter. We also see the Astral avatar. Spriggan slams Belial into the wall, but this causes the V Gear to hit the groove of the stadium wall. Bell and Belial uppercut and Bell tells Belial to rampage, with Belial using the speed to fly up in the air. Spriggan bursts mid air, and Shu is shocked. Bell's glad that he won, and Shu's impressed that he got the best Valkyrie to put into the V Gear. Bell says that it's only natural, Belial is constantly is evolving. Shu says that if Belial is defeated, it can take what it learnt and grow. Shu says he was able to see something good, but then points to the door, saying that visitors were also watching. Bell and Jingemon look back to see Ranzo's hair pointing out of a crack in the door. Bell is annoyed, but Shu says he should cherish his friends.
Hannah says that if he's supposedly only come to watch, he shouldn't go inside to the battle area. Ranzo claims that he hasn't forgiven Bell yet, and goes to Bell. Bell decides to finally show him the V Gear. Ranzo is impressed, annoying Bell a little bit. Ranzo realizes what they're doing, and Bell blushes. They both stare at eachother awkwardly, and Bell says that he was bad. Jingemon, Ranzo, and Hannah light up with smiles. Ranzo says that if he insists, he'll forgive him. Bell tells him to just accept the generosity of the Demon King.
Sorry it's a bit long, I tried to make it as detailed at possible.
