Marco looked at all 4 of them, they should be smart enough to know that they can't defeat him one against one. Then, he turned on the Chakra Gate, surprising the four monsters.
Marco: …Go.
Right now, Alma Elma was covered in wind and shot forward, Marco increased his reflexes' speed with the lightning and his mobility speed with wind, he saw Alma Elma trying to go with a knee attack, meaning she is serious with the fight.
He jumped on the side and grabbed her other leg, before throwing her back at the group with Gnome's support and her momentum.
The fight started, and the next one to attack was Erubetie, shooting a slime ball at Marco, he covered both of his hands with fire and grasped his hands, before he shot out a fireball.
The fireball and slime ball cancelled each other, creating vapor, before a second fireball came out from the smokescreen, surprising Erubetie.
The fireball was too fast for her to react, but Granberia quickly came in front of her and used her great sword to defend.
However, she was unable to take a balanced stance and when the fireball hit the sword, it exploded. Granberia and Erubetie were flung away from each other.
Marco put his hands back and used wind blasts to shot to Tamamo, she stood on her guard and waited for Marco.
He stopped some meters in front of her before jumping, raising one leg, Tamamo backed away before she would get hit from a stone pillar where she was some instants ago, then Marco covered his right hand with fire and pushed the air with his other leg.
The stone pillar moved to Tamamo, who broke it with an enchanted fist, Marco shot another fireball the moment after he pushed the air, and the fireball hit Tamamo when she attacked, since she was not fast enough to strike a second time, Tamamo fell in the ground some meters away from the burned area.
He finally took out his katana and turned around, pairing Granberia's sword attack, at his left he saw Alma Elma coming again, so he decided to use Chain-Claw, while covering his sword in lightning, making it sharper.
Like a chainsaw, Marco rotated on his own place and continuously slashed the same spot on the dragonkin's sword, sparks flew everywhere, Alma Elma and Tamamo backed away while putting their arms in front of them and Erubetie jumped on Marco.
The slime covered Marco's body and slowed him down, then Granberia stepped back before using Demon Decapitation on Marco, he let out a grin, which worried Erubetie, before Marco somehow moved in the slime body without any difficulty thanks to Undine's powers and used Daystar.
The first attack was on Granberia's wrist, she moved her arm away on instinct, but Marco moved a bit further and let out a big cut on her forearm, the lightning-covered sword came out from her forearm and pierced her stomach, then Marco grabbed the hilt with both hands and dragged the blade out, while cutting her side.
Granberia flinched with a pained expression and backed away. Marco stopped moving and lightning crackled around his body, electroducting Erubetie, she let out a pained scream and backed away, leaving Marco out from her slime body.
When he thought he could win, Alma Elma kicked kick legs while Tamamo kicked his head from the opposite side, making him fall in the ground with a small bruise on his head.
Marco quickly kicked the ground, dodging Alma Elma who almost hit him with a spine-breaking attack.
Then he stood up and appeared in front of Alma Elma, trying to slash her, but Alma Elma grabbed his wrist and used her other hand to land a palm attack on his elbow, with the intent of breaking it, however Marco blocked her palm with his other hand.
Suddenly, he jumped in the air, still with his arms attached to Alma Elma, and Tamamo accidentally punched Alma Elma on the stomach, making her flinch and release him.
She held her stomach in pain while Marco created another wind blast from his hands, shooting away Alma Elma and Tamamo while he flew in the sky, before landing in the center of the room.
Tamamo and Alma Elma were together and looked seriously at Marco, while Granberia was still holding her sword while magical power was coming out from her injuries, and Erubetie glared at Marco.
Tamamo: Heh, I didn't know you would have the Thunder Empress too…
Marco: You could find many things from cursing god… Are we going to continue? Because I can get even stronger.
Tamamo was completely filled with the power of Earth while raging wind came from Alma Elma, Granberia started to use Serene Mind and Erubetie made clones of herself.
Marco: I take that for a no… Alright.
He took a deep breath and started to use the Kurama Gate, surprising everyone from the power he emanated.
Marco: I'll make things easier, I won't use the spirits.
The spirits disappeared from Marco's body, and everyone stood on their guard, it may be insulting for them to hear that the opponent is deliberately holding back, but he had the right to do so…
Alma Elma disappeared due to the speed at which she was going, and was a meter away from Marco, to tackle him, Marco hastily extended an arm to her head and grabbed her face, his arm extended to Tamamo.
Her eyes were wide open when she saw Alma Elma coming at her, and got ready to receive the attack by tackling Alma Elma, she anchored her feet on the ground and tried to stop the attack.
But suddenly, Tamamo and Alma Elma were lifted and they were slammed in a wall, then another chakra arm appeared from Marco's back and almost hit Granberia, who was behind him and ready to slash him down.
She moved only her head, easily dodging his chakra arm, and slashed downwards.
But her attack was blocked from a second chakra arm that appeared below the first, and blocked the sword by grabbing the blade.
Marco turned around to slash Granberia, but she released her sword and used her bare hand to block his attack, surprisingly, instead of a slash, it was the hilt of the sword that hit her, since Marco held back his intent, Serene Mind had some difficulty figuring out his attack.
This was a trick he learned in the game from an archangel, by holding back one's bloodlust and intent to the maximum, it would make Serene Mind useless, and so, the hilt slammed on Granberia's head and sent her fly away.
The remaining one was Erubetie, she and her clones sent many slime balls to Marco, he easily dodged them with the Fallen Angel Dance and rushed at the biggest group of clones, then he jumped in the air and raised his free hand, which got as big as a car.
Erubetie's clones shot to the ones that would get hit, they grouped together and formed a giant slime fist, that connected with Marco's giant claw, which was smashing down whatever it was in its path, and… It got easily destroyed… What, you really expected that a slime hand could overpower a flesh-made hand? That shit is almost water.
The giant claw reduced the giant slime fist into a pancake, crushing Erubetie too, but since she was made of slime, she didn't gained much damage.
Marco fell on his feet and sighed, the only ones that could stand on their feet were Tamamo and Erubetie.
Marco: So… Are we going to finish this? I don't think I can be clearer on the difference between us without seriously hurting you.
Alma Elma and Granberia moaned in pain.
Marco: ...I'll take that for a yes...
Tamamo: …*Sigh* Yeah… I give up…
Erubetie: ...No… It's not over yet…
Marco sighed and turned towards Erubetie, then he walked towards her and said.
Marco: Hear me… As much as I hate you for killing me, at least let me alone for now… It is pointless continuing this fight.
Erubetie: ...Yo-
Marco: Look, I am not killing you, I am not killing anyone, as much as angry you can get, I won, but can you do something for me? I want you to believe in me… 'God, I sound like Naruto…'
Erubetie: What…
She was surprised from Marco's choice of words, while he just smiled.
Marco: Maybe you've heard it, but I am aiming for the coexistence between monsters and humans, there is no exception, everyone will live happily if I succeed. Even slimes.
Like I said to Alice, I will do what is necessary to make an happy ending for as many people as possible, certainly everyone. Just… Hope that I will succeed, that is what I am asking… Can you do it?
Erubetie stood silent for some seconds, before she snorted.
Erubetie: Alright…
*Ding*
*Special Quest[Successful]: Defeat Granberia, Alma Elma, Erubetie and Tamamo-no-Mae if they are revealed to be hostile.*
Marco: Fantastic!
He deactivated the Kurama Gate and stretched his body.
Marco: God… It was hard fighting with the Chakra Gate before…
Tamamo: Chakra Gate?
Marco: I am not using anymore the Nine Tailed Gates, since I came out from Undine's Cave, I learned to use the gates with a calm mind, and now I have those new for-
Before he could finish his explanation, an incredible magical power flooded the room, and everyone turned toward the large door at the end of the room, where the magical power came from.
Alma Elma: This power… Her Majesty?
Granberia: Alipheese…? She returned!?
The Heavenly Knights looked at each other in surprise, and then Alice's amplified voice was heard.
Alice: Welcome Marco, victor over my Four Heavenly Knights… No… Welcome traveler. Now, appear before me! The Monster Lord who rules over the monster domain!
Marco: ...Did… Did she treated me like a hero? Whatever…
Marco walked towards the large doors while ignoring Tamamo's shouts.
Tamamo: Wait, Marco!
Marco: 'It's time… Again… You stopped me from going in a rampage at the Witch Hunt Village, now I will stop you to commit such idiocy…'
*Ding*
