Pursuer

Who I thought to be W.D. Gaster walked into the room and said. "Your majesty." But when he saw us, the look on his face froze, then shifted to a defensive, then shifted to a confusing look when he saw taye's arm, A creepy smile crossed his face."souls." He raised his hand and taye's soul appeared and turned blue, as well as mine. He flicked his hand towards us and suddenly, our bodies were flung through the door, I caught taye and shielded him from the impact of the door, and the outside tree, I reached for the hilt of my fathers sword. I was angry, suddenly, the snow around us melted and I pointed the hilt toward Gaster, who was coming out of the door, with the roar of flame, the hilt glowed and fire extended and engulfed the front of it. When the fire dispersed, a blade was showing with a flame burning on the edge. I was too aggravated to be surprised by the sudden completion of the weapon. "So you have a sword, huh? Well, having it is one thing, knowing how to use it is another entirely." Gaster smirked.
I chuckled, My dad had been training me to fight 4 years prior... It was hard but it paid off. In an instant, I rushed him in a flurry of attacks. It felt like the strength in each attack was multiplied, and every now and again I saw flashes of blue. It caught the man off guard and I was able to prevail easily. I stopped the blade at his neck before delivering the final blow."Don't you dare, EVER, do that again". He nodded, and I gave him a hand getting back up. Suddenly, I could hear the whistle of an arrow flying toward me. I closed my eyes, when I opened them, My hand was closed firmly around the shaft of the arrow and the tip was inches away from my face, I was shocked. I wasn't the one who directed my hand to catch the arrow, how did I spin around so fast and catch it?
Be ready for what happens next, I will assist in any way possible.
Who are you?
I am the Angel of Annihilation, I witnessed your resolve before you fell, and bonded with your mind while you were unconscious during the fall. I will tell you more later.
A few seconds later another arrow zipped past my head and this time heading towards Taye. The next thing I knew, a gigantic bone rose from the ground and shielded Taye from the projectile. I pinpointed the source of the arrows, and made a bee line to it, trying to anticipate the next arrow, time seemed to move slowly, and when the next arrow came, I could see it and catch it easily. I looked at the tip, a smooth green substance coated the edge, thats when I noticed the one that had flew by right behind this one. I heard a pained reaction and turned around to see Taye with the arrow in his right arm, in a few second he fell to the ground,unconscious. In that moment, my rage flared, and through my emotion, fire was born. The flame turned blue and sailed through the air directly to the archer's bow. The man quickly dropped his bow as the flame engulfed it. He reeled and drew a dagger and charged me, I met him in a similar fashion and parried a swipe from the large knife and kicked him in the side, his body flew and hit hard against a tree. He fidgeted, and started to slowly get up, now that I could see him clearly, I saw the face of the man who had fired both the fatal shots to our parents. I extended my hand and as I grew angrier, more fire exploded from my hand. This time, with the man's arm in sight, within seconds, it too was engulfed in fire. Soon, the fire had spread to his shoulder,and then, his entire body. "Death by burning, they say that's the most painful way to go. Fitting for a heartless murderer." I said, in a low voice. I walked away
Was that a wise decision to kill him? Your EXP has increased. You are now LV5.

EXP? LV? 5?

LV is short for LOVE, which stands for "Level of Violence." Exp is also an acronym, standing for "Execution points." Every Time you kill someone, or something. Your EXP will increase, gain enough EXP, and your LV will increase. Your LV is visible by anyone skilled enough to see your SOUL, Giving people a reason to steer clear.
The man you just killed was LV 10. Some of the EXP he gained was recent, meaning he must have killed some of the monsters from the ruins

I walked back to the others, many of them wide-eyed. Toriel quickly recovered and walked quickly toward me, an angry look on her face. When we met she slapped me hard across the face. Suddenly, all the fighting caught up with me, and I passed out from fatigue.
