Riches and Bitches: I have a gate to an isekai and leveling-up system!

\'Peter!\'

"REEEEAAAAR!" Fay\'s scream continued as the lighting came down, burning everything in its path with the sheer might it was made of. The outburst of electricity persisted for much longer than it normally would as if something anchored it in the material world and refused to let it go. Unable to sustain itself in its current form of the bolt of light coming down from the skies, the lighting rapidly grew smaller and smaller… All the way to the point where it became nothing more but a half-materialization of Fay\'s aura… Or so would one say, if the girl could still bear that name, given how her eyes turned from the gentle blue they used to be before to the vicious yellow she had in her fox form. What\'s more, her eyes turned that of a fox, while the back of her hair lifted up, suddenly intruded by the presence of a lush bundle of hair that made up her tail. The aura of the lightning persisted in the form of sparks that gathered mostly in the area of Fay\'s fox-like features as she slowly rose up from the ground. Fay\'s Haori, the outfit that Peter picked up for himself, changed too, its colors growing more vibrant in this new illumination coming from the sparks of lighting dancing all over Fay\'s aura. "Hisss…" With her eyes losing all semblance of sanity, Fay hissed at the bunched group of the last few enemies that survived the onslaught thus far.  And before any of them could even react…

"RAAAAAARGH!"

Another underworldly scream filled the air, stunning all those unlucky enough to hear it. And what was even worse, it was now infused with the power of lighting that only further enhanced the shocking effect the scream had on simple humans. The warriors weren\'t amateurs, though. Only a group of proper veterans could make their way that far into the celestial forest. And now they proved their experience, taking only a short moment to regain their composure… But it was already way too late. At the same time as Fay uttered her cry, the sparks of lighting around her intensified, only for the girl to disappear from where she was, appearing right next to her attackers in a time shorter than it would take one to blink their eyes. Her eyes were burning with hate. Her aura quasi-materialized under the influence of the power of celestial lightning. And when she clawed at the men who were the direct reason behind Peter\'s wounds that were as heavy as they were strange… The power of the lightning silently followed her command. Fay slashed with her hand, clawing at the nearest man. And while her nails couldn\'t even scratch the armors those men wore, the line of lighting that persisted for just a fraction of a second before suddenly exploding all of its energy outwards was more than capable of achieving this feat. "DIE! DIE! DIE!" Drunk on her madness, Fay slashed her nails all around, ripping her enemies to shreds without even a single hint of mercy. In just a few seconds, not a single enemy was left to stand and oppose her. And right as she brought her nails down to brutalize their insolent corpses… A powerful fist to the girl\'s stomach sent her flying a few steps back. "Snap out of it!" Fay\'s mother screamed right into her daughter\'s face, leaping after her right as she sent her own flesh and blood flying. "He is still alive!" But even those words failed to make it through to Fay\'s hate-consumed and power-drunk mind. In exchange for the word of caution from her mother, Fay slashed at her, using the very same power of lighting from before to throw the mature celestial fox away. And as it turned out, not even a fully grown kin of Fay could resist her newly-awakened power. But the woman wasn\'t anywhere close to giving up. "Would you rather rip those fuckers to even smaller shreds, or maybe try to help your wounded mate?!"

For the very first time, Fay\'s mother actually raised her voice. And not to shout, not to let her voice cut through a greater distance. No. This time, her mouth shouted to scold her. And the absurdity, abnormality of this fact finally brought enough to bear on her mind to let Fay snap back to her senses. Deprived of the madness that drove it, the power of lighting quickly started to dissipate into thin air… Something Fay couldn\'t even notice with how she instantly darted to where Peter fell. She leaped the last bit of the distance only to land on her knees and slide the last few inches, stopping just a hand-width away from Peter\'s injured flesh. And seeing the state her supposed mate was in, Fay\'s eyes filled with tears, only for a single word spoken in a pained voice to come out of her mouth. "Peter!"
