Yuno looks meaningfully at Mimosa, who continues to heal from her serious injuries.
Klaus: What were you thinking, coming back for me? I gave you a direct order, let alone a mission to complete! That means getting to the treasure hall by any means necessary!
Yuno: First we defeat him. Then we go the treasure hall... as a team!
Veldora: THAT MY BROTHER
Just before that showdown could begin, Noelle catches up with Rimuru and Asta, their weapons and grimoires drawn as she stands by side with the fair skinned individual while Asta boldly charges.
Asta: You're facing us! You ready for this beatdown?!
Lotus: Oooooh, I guess my count was off by one more. And where did you come from, little girl?
Rimuru : She was with us, pardon her tardiness. But don't take her lightly, it would be a poor lifestyle and health choice.
Lotus: Your friends are coming out to play one by one. How positively delightful!
Luck suffers another flashback, this time to the day of his mother's funeral as everyone is gathered around literally just minutes after she is buried and committed to the Earth.
???: From what it sounds like, she just upped and died.
???: She was under a lot of stress, that's what their attributing her death to as well. But where does her son fall in all of this?
???: Poor thing must be heartbroken.
???: Yeah but that's the thing, he's just been smiling ever since the tragic day. Strange one Luck Voltia is indeed.
Luck: He's mine.... stay out of it, you three.
Noelle: Luck, wait!
Rimuru : There's no telling what this guy is capable, let us help you.
Luck: HE'S MY PREY AND MY PREY ALONE!
Luck's mother: Win!
Luck: I will win! And dedicate my victory to you, mother!
The Cheery Berserker blitzes past Noelle, Rimuru , Asta like a certain bird evading capture from a coyote, making his way towards Lotus.
Luck: I will take him on alone! STAY BACK!
Rimuru : Damn it this battle-drunk idiot!
He kept his pocket knife close.
Luck: I don't need friends to win a fight! I only need my strength and my strength alone!
Noelle: Please, Luck! Let us help you fight!
His lightning crackles even fiercer as he reaches his mark closer and closer.
Luck: I can do it, on my own! I'll end him and finally earn my mom's acceptance.
Asta: Fine, have it your way.
Noelle: Asta!
Rimuru : No he's right. Luck will do this of his own volition, Noelle.
Noelle: Not you too!
Rimuru cracks a flashy and signature smile.
Asta: But...
Lotus: Is that all you've got... this isn't really the time to be holding back, you know!
Luck: I'll do it, I'll win... for you mom! I need her to accept me or I'll be all alone!
Lotus shoots one giant smoke cloud at Luck again before it gets crudely slashed by Asta, catching Luck by surprise while
Rimuru:SLIME MAGIC:ICEBERG SHOT GUN
He was firing ice crystals
Asta: You do what you have to, Luck!
Rimuru : But so will we three! YOU ARE OUR COMRADE! OUR BROTHER IN ARMS! AND DAMN IF YOU THINK YOU'RE GOING AT IT ALONE THINK AGAIN! YOU.... ARE OUR FRIEND!
Luck: I have to beat him on my own!
Asta and Rimuru come after Lotus as they slash wildly at the Diamond Mage while Tyrus shouted at him again.
Rimuru : AND WHO THE HELL TOLD YOU THAT?!
Asta: THAT'S JUST NOT HAPPENING LUCK!
More smoke shoots from Lotus's hands as Asta slices and hacks away.
Asta: I'M NOT DONE YET!
Luck finally snaps out of his blood obsessed battle-rage as he reflects on Rimuru , Noelle and Asta fighting to save him from his self.
Luck: In some way...
Asta: I don't know what you think of me but it doesn't matter, but do what you have to! Because I guarantee, we will too!
Luck: I wasn't even trying to notice but-
Noelle: You may be a battle obssessed nutcase, but you're the Black Bulls Resident Battle Obssessed Nutcase. I can't believe I'm saying this, but you're a good teammate and a great mage.
Rimuru : And I don't feel like repeating myself so I'll shorten up! You.... are..... our... damn friend Luck Voltia!
Luck: Trying not see that even I had friends who I can truly count.
A picture flashes in his head as he gets good look at Noelle, Rimuru , Charmy in her human form, Gauche, Asta, Gordon, Finral, Captain Yami, Magna, Millim and Vanessa.
Luck: Sorry, mom.... but I'm not alone in this world! Not anymore, I have a family that like you, loves and understands me!
Lotus retreats back as he sees a slightly exhausted Asta and barely spent Rimuru .
Luck: You're right! It's so much better to fight with friends than doing it alone!
Asta: Sure does!
Rimuru : Glad you're finally seeing the light, Luck.
Noelle quietly hmphs but stands relieved, glad Luck is back to normal... well as only normal as he could be as all four Black Bulls activate their grimoires ready for the scrap ahead.
Lotus: Well this isn't good for me... there's four of you and only one of me. I guess that means I should stop holding back then.
He creates yet another smoke cyclone, the polar oppposite to one of Rimuru magic as it envelops all four Magic Knights.
Lotus: Smoke Creation Magic... PRISON OF THE FALLEN KING! Poor foolish little children, there's no escaping this field of smoke!
Rimuru : Yeah.... we don't care about your silly little smokeshow dude. The thing about us Black Bulls?
Asta: Is that we don't lose to anyone! AND THAT INCLUDES YOU!
Yuno: Time to go... this ends now!
Klaus: W-What are you planning?!
Intense winds pick up as Yuno's grimoire glows intensely!
Yuno: Engaging Wind Magic! Swift White Hawk paired with Wind Blade Shower!
Klaus's jaw almost dropped to the floor. He knew Yuno possessed massive power for a commoner but to be able to set off a dual casting? Unheard of!
Klaus: He's performing a dual casting?! AND ONE WITH SUCH MASSIVE MAGICAL POWER!
Mars looks on, somewhat... intrigued? That this boy had so much magical power to his name and body so the least he would do is take whatever pitiful attack he could muster before he ended Yuno's life.
Yuno: Time to get out of our way, Diamond Kingdom mage. This dungeon belongs to the Clover Kingdom's Golden Dawn and we will reach the treasure hall first!
He fires off his attack simulatenously just as Asta continues helplessly to slash through the smoke cyclone Lotus had trapped him and the other Black Bulls in.
Asta: I'm cutting, cutting and cutting! But it just keeps coming back!
Noelle: Here, try this!
She fires off a water ball but much like his slashes, had no effect.
Rimuru : It's like not even our best attacks are having damn lasting effects to this. This is the power of the Diamond Kingdom's best? Ya know if they weren't such evil and pretentious bastards, I'd actually tip my hat to him.
Luck: HAHHHH!
Luck tries his best, kicking through the plumes.... only to get the smoke to grow more intensely and actually hit Asta, pushing back the non-mage. He then thought quietly to himself.
Asta: Anyone else.... feeling kinda dizzy?
..Asta: Anyone else.... feeling kinda dizzy?
Noelle: This place is filling up with smoke, if we're not careful... we're all surely going to suffocate in this magic! Our only chance is to beat the spellcaster and beat him fast.
Luck: I can sense him and his magic power... he's moving every so often as so we can't detect him being stationary. But I have a good idea on where he might be. If we attack now, he'll most likely dodge it. What did I pick up on his fighting style so far? That's right, he prefers fighting from a distance as well not needlessly wasting his energy. But when he's in the smoke, he's faster than even I am! Our best shot.... is to blindside him, and I know just who can do it.
Luck: Noelle, Rimuru ! I have a plan, but I'll need your help.
Rimuru : Uh, sure what exactly did you have in mind?
Lotus: This spell's effective but it's taxing on the body since it's taking out a lot of magical power... I may not be young and fiery like you four, but I can keep this going all day. Of course the only other detriment is that I can't see my opponents. I would hope for your sake you don't get foolish ideas. I can sense your magic power's so it'd be a waste of time in resisting and launching sneak attacks...
He stops talking when he sees two glowing lightning eyes, shoot at him from a distance, while Asta, Noelle and Rimuru got into their positions.
Noelle: How long it will take you to charge up?
Rimuru : Given I haven't expended that much magical power? Not even a minute, I just gotta hope Luck gets him in the perfect position. Alright, Asta... time to fly, brother!
Noelle: He's right! Up you go.
She shoots a water ball into Asta's back sending him flying into the cloud.... they both wait until they a thunderous clang and someone hacking up blood.
Noelle: NOW!
Rimuru : Icy slime Magic: CRYSTAL SHOT GUN!
He blitzes onto several bricks up top as he lauched his bicep across Lotus's chest and rams across another brick layer, effectively taking the enemy out for the count.
Lotus: UGHHHHH!
The dust settles as Rimuru jumps back to the others, the ice on his body now gone as they see Lotus, now out cold as Luck and everyone explains the takedown of the Smoke Mage.
Luck: First I cornered him!
Noelle: Then, using every drop of my magic power and in a fraction of second, so that he wouldn't notice what we were up to. UP YOU GO!
Luck: With Asta not possessing any magic, he wouldn't be able to sense him coming from a mile away! Then Rimuru finished the job and turned his lights.
Noelle: NOW!
Rimuru : ON IT!
Noelle: That went really well.
Luck: You know you were right earlier, it is fun fighting with friends by your side.
Rimuru : Heh. Glad to see it from you, ya damn maniac. Teamwork makes the dream work!
Meanwhile with the Golden Dawn.... Klaus and Mimosa couldn't pull believe what they were both seeing. Between seeing Yuno fire off a dual casting spell and firing it off. They had been sure this intruder was most certainly killed or at the very least neutralized to the point he wouldn't interfere... but yet. Mars will standing with only a few scratches on his body as Yuno's wind magic continued to dissipate around him. Yuno had a hand on his knee, laboring for breath as we get a look at what has stolen the Golden Dawn's breath in a sense. A giant crystal blunt tipped sword, generated from out of nowhere trained on all of William Vangeance's members
Klaus: W-what type of monster are we dealing with?! How is this even remotely possible!
Mars: Now..... I shall give you the proper respect. And kill you with my tremendous power, cockroach.
(Rimuru is going to be using different ice slime magic in the dungeon)
