Glitched Isekai

"Bastards!" Sam said, watching everything from the Nexus. 

All 3 battles were going poorly as more and more Avengers appeared in the Nexus after being killed. 

At the Four Elements Sect, Thundar was already injured. And while Alex had managed to banish 2 demons, there were so many to go. 

She had already been killed twice and Sam kept sending her back to fight, as he did with the other Avengers with her. 

This battlefield was the most tragic as it had the most amount of demons attacking. 

Sam had sent the team that failed to get to the Poison Sect consisting of Buffy, Faith, Hermione, Alice and Natasha to help out. 

"Avengers! Ensemble!" Alex yelled, trying to rouse the fighting spirit of the group

"Assemble! Assemble!" Natasha corrected her as Mindy giggled at the gaffe. 

They needed the lightheartedness in such a tough and daunting battle.  

Even when Buffy and Faith destroyed one demon each, it took them alot of effort just to kill one demon, and there were so many more to go. 

Sam decided to send Aria and Arisa to the battle too, as this was their home. 

"Daddy!" they screamed, seeing Thundar injured, but still fighting valiantly. 

Aria activated her earth and fire lava form, instantly charging at the demons attacking her father. 

Arisa activated her water and air tempest form, her eyes glowing manacingly as she too joined her sister in attacking the demon.

At the Silverleaf Forest, Tauriel dragged Ulandir's badly burnt body back through the portal to Aristal as the other Avengers covered her retreat. The Silverleaf Forest was already lost as the whole forest burned to ashes with tens of demons walking around killing every living being they came across. 

As Tauriel exited the portal on the Aristal side, Sabrina, Cameron, Max and Violet were left behind and Sabrina destroyed the portal, preventing the demons from going through. 

Cameron, Max and Violet fought till they died, managing to help Sabrina banish 3 more demons before Sabrina stood alone, surrounded by multiple demons. 

She smiled as she cast a huge devastating spell, destroying as many demons around her as she could, killing herself in the process. 

--

Sam had abandoned the fight against Magdalena and Astaroth, letting the Avengers there Raven, Phoebe, Annabeth, Selene, Yuriko and Rey fight until they died. 

Phoebe managed to banish 2 demons there before dying while Annabeth's Master Bolt actually killed another 2 demons. 

However, the weapons of Selene, Yuriko and Rey didn't do enough damage, even though Yuriko's adamantium claws and Rey's lightsaber did manage to damage the demons. 

Finally, they all died and reappeared in the Nexus. 

--

Sam had decided to send everyone to the fight at the Four Elements Sect as that was the only one still worth fighting for. 

He watched in the Nexus as Phoebe, Alex, Sabrina, Buffy and Annabeth banished the demons one at a time, but there were still so many demons to go. 

He decided to summon another familiar. 

"Nexus, I summon a demon killer" he said, wondering if the wording will summon anyone else besides another slayer like Buffy or Faith. 

He lay down and let the pleasurable process take place. 

Within moments, a pair of hands appeared, as did lips surround his already cumming erect penis. 

A beautiful brunette started forming out of his body and as she turned around, she recognized her as Wynona Earp, who was acted by Melanie Strofano in the TV Series. 

It they didn't take long as she detached herself from his body, rocking a few more times before both of them climaxed together. 

As he had already done this so many times, he established the mind link with her which explained everything and she got off his cock with a determined look on her face. 

As Alex and everyone else was already outside, she exited the Nexus completely naked, holding her demon banishing pistol Peacemaker, immediately joining the fight. 

As all the other teams had failed, Sam used all his Avengers in this battlefield, pouring all 26 Avengers that he has summoned into the battle.

With Alex, Phoebe, Sabrina, Annabeth, Buffy and Wynona able to banish demons, the 30 or so demons started dwindling, but not without a huge fight. 

Meanwhile in the Nexus, Sam had already summoned another familiar. 

As she got off him, she immediately donned an exoskeleton and wielded a huge sword, even though she was naked and exposed inside the suit. 

Sam looked at her, Rita Vrataski the "Angel of Verdun" who was acted by Emily Blunt in the movie the Edge of Tomorrow. 

She exited the Nexus with all guns blazing, her suit firing missiles and bullets endlessly, joining the other Avengers who were also firing their firearms endlessly at the overly powerful demons. 

However, Sam realized that even with firepower brought by Rita and Trix, they were largely ineffective against the demons who only seemed to be able to be killed or banished by those that specialized in demon banishing magic or had demon destroying weapons like Annabeth, Buffy, Wynona or even Hermione when she used the Sword of Gryffindor. 

Roughly an hour later, all the Avengers were exhausted as they banished the final demon. Sam was healing Thundar who was badly injured and the other Avengers were healing each other and resting. 

The scene of the battle was disheartening as the territory of the Four Elements Sect were largely in ruins. Many of the sect members were killed, leaving only their most powerful members which luckily included Aria and Arisa's father and mother. 

Suddenly, while talking to Thundar, Sam stood still as an alert flashed through his mind. It was Queen Serene, calling for help. 

"What is it?" Thundar asked. 

"Aristal was under attack. Thousands of demons had descended on the capital!" Samsara answered. 

"We have to get going!" Thundar said. 

"No. You and your family stay here. With thousands attacking, the best we can hope is to evacuate the city. There is no hope of winning" Samsara replied. 

"Are you sure you can handle this?" Thundar asked. 

"It's best you remain here. If we are to mount a counter attack, we need the element of surprise. Asteroth and Magdalena has betrayed us, but they don't know you've survived yet" Samsara said. 

He had explained to them what had happened, so Thundar already knew the fates of Asteroth, Magdalena, Ulandir and Balthazar. 

Thundar thought for a while and nodded. "You go back to the capital. I will try and gather more forces from over here and stand ready" he said. 

Sam shook his hand and he vanished with the other Avengers into the Nexus. 

Within an instant he reappeared next to Queen Serene in the meeting room.

Queen Serene sat at the head of the table with her advisor Merlin next to her. The spymaster Shadow stood silently behind her, while Roland and Ulandir, who was already healed, sat at the other seats.

Loud booming could be heard coming from outside the castle. 

"As you can hear, war is upon us. Samsara! What happened to the other sites?" Merlin asked. 

Samsara took his seat and was just about to inform them about Astaroth and Magdalena's betrayal when suddenly he heard a familiar voice. 

"You wouldn't be thinking of starting the meeting without me I hope?" the female voice said. 

Sam froze and turned around, finding himself face to face in front of Magdalena.

With a sudden move, she placed her hand on Samsara's forehead and he suddenly screamed. 

He felt the life being pulled out of him and he could only stand helplessly as he couldn't move or even form a thought and was thus unable to let the Avengers out of the Nexus. 

His level was going down at a rapid rate. From a level 33, it dropped to 32, 31, 30, 29, 28 .... all within seconds. 

"What are you doing?" Queen Serene said standing up. 

Suddenly a black blade sliced towards her neck, only to be blocked by another black blade. 

It was Astaroth attacking, trying to assassinate Queen Serene, but luckily the Shadow blocked his attack. 

"Betrayal!" Merlin yelled summoning a fireball and firing it at Asteroth. 

A battle broke within the meeting room.

"My my my. They call me the Eternal Witch because I've lived for a long time. But that's because I use the lifeforce of others to lengthen my lifespan. But I don't seem to be absorbing your lifeforce. I seem to be absorbing something else..... Oh! I've increased in levels! What a pleasant surprise!" Magdalena said as she had already gone up from Level 40 to Level 66. 

For Sam, there was only a few levels left as he was now a miserable level 7, then 6, 5, 4, 3, 2, 1. By now, Sam had lost all the skills he acquired at every level. 

At level 1 as the last level disappeared the 3 magic skills he first requested, namely [Summon Familiar], [Heal] and [Magic Missile] disappeared from his list of skills in the Nexus. 

At the same time, all the Avengers looked at each other as they faded from existence. 

Magdalena was happily enjoying her leveling up when she noticed that it stopped. She looked at Samsara and was surprised to see a gorgeous girl instead of the handsome young man.

As he had lost her [Heal} ability, Samsara reverted back into Sharon's female body. 

Magdalena was now level 73, the most powerful being in the room. She looked at the pretty girl before her and released her hand from her head. 

Immediately Sam entered into the Nexus, escaping from Magdalena's reach. 

As she was already so weak and drained, she passed out. 

Outside the Nexus, Magdalena had already defeated the rest of the heroes by herself. The Shadow managed to escape but the rest were soundly defeated and were captured. 

She absorbed Ulandir and Roland's lifeforce, leaving them empty husks on the floor, their whole body wrinkled and old as she absorbed their lifeforces. 

She ignored Merlin since although he had lived for a long time, he was now already old and at the twilight of his life,

Then she turned to Queen Serene and absorbed her life force too. 

"What is this? Why is your life force so robust and abundant? It's like an endless supply for life. I will be able to live forever just eating your life force, You will be my life battery" Magdalena said happily. 

--

Hours later, Sam opened her eyes and looked around the Nexus. 

"Hermione? Mindy? Alex? Anyone!" ahe yelled. 

The Nexus was devoid of anyone, with only the created objects by Alex all over the place. 

"Nexus, what is going on? Where is everybody?" she asked. 

[Upon resetting to Level 0, you no longer have the ability to summon familiars. Because of this, all your familiars have been unsummoned]

"What? No!" Sam yelled. 

She looked at her own body, quickly removing her robes. She groped her breasts and felt the warm slit between her legs.

She walked to one of the many full length mirrors in the clothes area and recognized Sharon's body. 

"Shit, I'm really back to square one! I should have sent Raven instead of joining the meeting as my real self!" she said to herself, regretting not taking more precautions. 

She looked outside the Nexus and was shocked. The whole city of Aristal was burnt to the ground. There was nothing left, not even a blade of grass!
