Bellerophon

Medusa kept running around the Chimera. She imitated Kisuke's actions and led it around the whole stadium, killing some of the clan's members along the way. Although dead members are desirable results, that isn't her main goal. Unknown to everyone but Kisuke who saw what she's doing, Medusa is secretly setting up magic circles for her magic for future use.

Although she needs to kill it as soon as possible, she still has to plan for their future actions and planting possible trump cards could be their key to victory. Medusa also didn't forget their real goal of securing the blindfolded girl. If she's successful in getting her, they didn't need to fight any of them and just escape.

After a few minutes, she's done setting up her magic and controlled the 12 chains to attach to different parts of the Chimera's body.

Using the chains, she kept slashing and going around the monster which enrages it greatly. Medusa is waiting for a single moment that it'll lose its patience and put all of its Mana to an attack. And just as she expected, when she put herself opened for an attack, the beast immediately took the bait and put all of its Mana to its claws intending to cut her into pieces.

Before it could do that, however, faster than the beast Mana gathering, four chains wrapped around the two necks and tail. Pulling it with all her might and transferring the sharpened Mana to the chains she pooled inside her before, the chains dug to its flesh and eventually beheading all of its head at the same time.

The Chimera stopped all of its movement with its heads dropping on the ground with a loud thud. Everyone is silent. Even the Manticore who is chasing Kisuke around stopped for a moment. The Chimera died before it can even let out a cry.

"!?" Watching all of this, Petter felt relief that he didn't have to fight her. He underestimated her too much. Although he can also defeat the Chimera, he can't do it as fast or as easy as Medusa did, 'But she used a lot of her stock Mana... That unknown guy is also a problem... But as long as I can push her to use that, everything will be fine. I guess should just bring out everything and scare that guy... It looks like he the type that wouldn't hesitate to abandon her if things get dicey?'

Medusa first looked at Ana before deciding against saving her for now as Petter tightened his hold on her. She turned around to help Kisuke deal with the Manticore but she stopped her steps when she heard Petter spoke, "Not so fast..."

Another snap of his finger, a large number of clashing chains was heard throughout the whole area and one by one, a bunch of monsters appeared slaughtering everyone in their way. A total of 7 Chimeras and 3 Manticores.

"I-Impossible..." Medusa muttered, "Where are you getting all of this extinct beast?"

"I don't have any obligation to answer your question... Just defeat all of this and I'll give this girl to you." Petter replied with a sneer.

Instead of entertaining him, Medusa immediately went to Kisuke's side to help him retreat and stayed quiet to wait for him to speak.

"I don't think I can do this..." Kisuke spoke with a frown on his face. The black cat, Yoruichi jumped back to his arms.

Medusa already expected this and sighed, "Go... I'll cover your back. The teleportation circle isn't far from here..."

"...Thanks..." Just a word of gratitude and Kisuke turned back to run to the direction they entered. Medusa did her best to fend off the monsters' attacks from all side and she received several wounds from it, some of which are intended for Kisuke.

They reached their target and Kisuke immediately stepped on it. He turned back and saw Medusa's disheveled appearance with multiple cuts all over her body. Her maid uniform already turned into a rug and can only cover her important parts. The only unharmed part of her is the pair of glasses and the purple gemmed pendant hanging on her neck, both of which are a gift from Kisuke.

"...Take care..." With a sad smile on her face, Medusa said her final goodbyes. Chances of her surviving this ordeal are low and if she wants to save Ana, she's going back to ether state where she would suffer for another three generations.

There are so many things that she wanted to say to him as he showed her a new door where she can go and enjoy life even for a short period of time. Although she wanted to try and discover more things, what she had this past few days are already enough for her to remember for multiple lifetimes. Looking back, she's already more indebted to him than Ana multiple times.

"Thanks... And this isn't the end." With those words that don't seem a goodbye, Kisuke disappeared in motes of light still with a large grin on his face.

Medusa was dumbfounded, but shook her head and smiled wryly, 'It's probably just his way of comforting me...' She wanted to talk to him more, but that's already impossible. Now that she's sure that Kisuke is safe, She can stop holding back. 'I have still two cards left... I'll use one to disrupt everything and the second one to escape. If I can toss Ana on the magic circle, I can bring everyone here with me to the afterlife.'

With strengthened conviction and confidence, she faced the army of monsters, crouched down and finally, slashing on her own throat, a red magic circle appeared in front of her.

'This is it!' When Petter saw this, he immediately turned around to flee bring with him the unconscious girl. The other who saw this also started fleeing. Heck, if the strongest guy from them started fleeing after seeing what Medusa is doing, why wouldn't they?

From the magic circle, she summoned her Divine Beast which has been sleeping inside her Divine Core all this time, a Pegasus. Medusa's Pegasus is incredibly weakened due to her state, but it's still a Divine Beast and wouldn't lose to any of the monsters in front of her.

Along with the appearance of the awe-inspiring beast, from Medusa's both hands, appeared a shining golden bridle and a whip as a set. She immediately put the bridle on Pegasus and rode it, flying with it to the sky.

Pegasus shined in white light along with Medusa, "Bellerophon!" And as if a bolt of divine lightning, they descended with extreme speed leaving a trail of white light. A split second later, they swiped down in the middle of the roaring and fleeing monsters, killing them in blood and gore along the white light's wake.

A few seconds later, everything settled down and everyone peeked from their hiding places to the devastation created by Medusa's magic. All of them shuddered at its might that it might as well as strong as a big missile that annihilated everything.

Although it's strong, it's still on the level of a normal mage capable of casting large scale magic. High-Class Devils or Humans with strong Sacred Gear is capable of the same destruction.

These people have never seen a large scale battle that shaped the terrain so they were in distraught after witnessing one. But unknown to them, Medusa already approaches Petter's side and impaled the arm which is holding Ana. In an instant that their mind became occupied, Medusa used that chance to snatch her goal, the one she's indebted for and shouldn't have been in this situation if not for her.

While carrying Ana in her arms, Medusa bolted with all of her remaining strength towards the magic circle to exit this place. She didn't have any reason to use her second trump card as it isn't needed. Thinking that she could meet him again, she ran with all her might. Even though the scenery is grotesque, her heart is light as a feather.

But her wishes were popped like a bubble when she suddenly felt a burning sensation in her chest and she instantly lost control of her body and let go of Ana. She tumbled down and rolled for a few meters before stopping. With difficulty, she turned her head and looked at her chest. There is a knife sticking out of it and the only person who could have stab her is the one she's trying to save, Ana.
