Illya, you gave me another reason to not like you. So, the episode starts off with the gang snug in a rug sleeping in the cabin in Sparking, And Hannah tells Bells Gramps that Bell's currently missing and then Bell's Grandpa looks concerned, then we see Rashad and shockingly when Hannah said that he was intrigued. I didn't really get how he felt about it. Illya and Bell go up the top of Lui's Island and get ready to battle, (Don't forget that if Bell loses this battle he'll have to become Illya's maid). They talk a bit and I have no clue what they're talking about for a bit (She's probably reminding Bell about the deal). Hanah's freaking out because Bell's lost (No wonder people ship them) and she wakes up Wakiya and Ransou says that Bell's probably having a battle. Valt seems a bit confused but Ransou and Bell's Grandpa explain that usually when Bell's gone he's battling someone. Basarah guesses that he's battling Illya because of his loss in the Battle Royal. Wakiya's ticked off but I don't exactly know why maybe something about the battle? And Ransou says just let 'em battle then Wakiya screams at him (JUST START THE FREAKING BATTLE). Finally, Illya does something to her Bey, and Bell's wondering what she's doing and Illya explains the QUAD DRIVE SYSTEM! Yes, everyone, the QUAD Driver system is in the freaking anime! Let's go! She adds this part that looks like Wave or something idk. Bell says the Demon King is gonna win, you know, usual Bell stuff and Illya explains that she Burst Belial in the Battle Royal, and Bell gets mad and restates that he's gonna win. (Goodness I've literally written a paragraph and THE BATTLE HASN'T STARTED!!)
Illya does her wannabe roller skater dance launch and stuff and the Battle finally begins! Ifrit takes the center and holds it down, Bell goes straight in with a Dynamite Bomb, but it doesn't do anything. Illya is like, is this Belial's true power and Bell be like ah naw we just gonna spam Dynamite Bomb until you burst and that was the dumbest strategy ever. If you don't know, Dynamite Bomb requires a lot of speed and power, spamming that move would literally kill your stamina, we'll get to that in a moment. Belial speeds up on the ramp and uses Dynamite Bomb again. (Seriously Bell put more thought into this). It gets moved away from the center (Barely) and Ifrit just takes the center again. Illya mocks Bell but, Belial speeds up again on the diverters and what move did he use? Well, it was Venture Shoot-- Nope, it was Dynamite Bomb and this one actually did something and sent Ifrit flying into the sky but, Belial started wobbling and losing spin (This is what happens when you spam Dynamite Bomb) and Ifrit landed on the Dynamite Ramps or whatever they call it. Ifrit speeds up and Illya goes full-on cat mode literally hissing and powering up. After Ifrit speeds up it uses the Dynamite Ramps to speed up even more and use Magma Smash sending Belial plummeting into the ground and bursts. Illya has won the battle.
Rashad and the gang go up the mountain and hear a Burst Sound so they immediately assume Bell's up there and hurry up the trail. Bell asks for a rematch, but Illya just responded with "That was too easy, this is boring"
You little-- . And Bell just wouldn't stop asking in till everyone got up the mountain, Bell tries hiding the fact that he lost but, Illya just tells them that Bell is cooking curry, Bell says no but Illya says your my servant now, so do it. Bell makes Illya some curry and he's not happy, if looks could kill then R.I.P Illya but, Illya just eats the curry as nothing happened. The gang chows down and Hannah talks about Bell being Illya's servant and Basarah probably said "It's his fault for agreeing" or something along those lines. And Wakiya walks up to Bell and Illya with a picture of after the battle Royal, everyone was ticked off with Illya in that picture lol. Illya "Accidentally" dropped her spoon and asked Bell to pick it up and get a new one, Bell protests but Illya reminds Bell about the deal. (Man, Illya's really milking this). Bell and Illya talk about Lui and then Illya orders Bell to go spy on Lui, Bell reluctantly agrees and runs off, Rashad and Illya talk a bit but, now it's time for Bell to spy on Lui. Bell gets in this small cart that had something for Lui apparently, Lui picks it up and leaves, Bell gets out grabs his phone, and starts a call with Illya, (When did they get each other's numbers?) Anyways, Bell records Lui practicing with his new Guilty Longinus, Illya asks Bell to zoom in so that's what he did. Bell zooms in to see the new Guilty Longinus, Guilty Longinus' eyes glow towards Bell and Lui looks at him. Lui introduces the new Longinus and practices with it, Beys pop out of the machine and go straight for Longinus. Longinus speeds up and slams into half of them, all the Beys go flying and burst, Longinus rams through a couple more Beys and they burst too. Lui laughs as all the Beys burst right next to him (You know you're going to have to clean that up right?). Lui laughs more and Bell just says "Guilty Longinus is so powerful" or something along those lines.
Overall: For a filler it wasn't that bad of an episode (I didn't like Illya being in it but whatever) Overall 7/10, would've been an 8 but Illya was in it
