Frisk wasn't always a bad person, they even became friends with Chara in the past. That was when a being known as 'the Player' took control of Frisk, along with the timeline. And even when the player was gone, Frisk was was paranoid they'd come back. They used their DETERMINATION and combined it with LV and HATE to kill off the Player and destroy all the timelines, at the risk of all their friends. All monsters, Chara, and six humans before Frisk who were brought back to life in the timeline. However, Frisk regretted everything they done and sacrificed themself to give everyone a happy ending. Even Asriel was back with all the others, everyone was finally set free from the endless hell.
But something changed.
The timeline reset itself suddenly, removing the HATE that broke their soul. Frisk told Chara resetting can't heal a broken soul, but this wasn't a normal reset this time. It was a reset known as 'The Very Final Reset', something that not even Chara or Frisk could really understand. It was the most powerful reset, the only one that can heal a soul and take it all back to the very start. Frisk and Chara still remember everything, though. It was still the same old world, same old issues, same old monsters, same old everything. For Frisk, it was a brand new start they didn't deserve. For Chara, it was more memory-based torture. It was going to be much more different, since the reset also banished any entrance of the Player for good.
Frisk woke up on the bed of golden flowers, confused as to what happened. They stood up, only to notice the familiar kids around them. One was a pale-skinned girl with pale blonde hair tied into a ponytail with a red ribbon and light blue eyes, wearing a white t-shirt with light blue stripes and long grey pants. One was a pale-skinned boy with brown hair and orange eyes, wearing a pale brown tank with orange stripes, shorts, and a 'manly' bandanna tied around his head. One was a dark-skinned girl with dark brown hair in a bun and deep blue eyes, wearing a light-blue and dark-blue striped shirt and a pink tutu. One was a pale-skinned boy with black hair and purple eyes, wearing long pants, a purple sweater with black stripes, and glasses. One was a tan-skinned boy with dark brown hair and green eyes, wearing a white-and-green striped sweater, long brown pants, and an apron. One was a tan-skinned girl with dark brown hair and yellow eyes, wearing a pale brown and yellow striped sweater, a yellow bandanna around her neck, long brown pants, and a cowboy hat on her head. They all were unconscious on the ground, leaving Frisk more confused.
The close-eyed human stood up, "Okay, great. I'm somehow alive again and I'm with the kids I tricked when I was alive, who of which are passed out and here with me in this hell once more!", they said to themself in frustration, "...Of course, of course...", they continued while calming themself down. Then the six other kids woke up feeling disoriented, probably from falling for the third time. Frisk's eyes opened briefly, "Uh...", they muttered. "Where am I?", the boy with glasses asked, "What is this place?", the girl with the ribbon added. Frisk was going to actually help this time, no more lies or fears anymore. "Um, we fell under a mountain.", Frisk answered them calmly. The six looked up and saw the hole where Frisk always fell. As they looked back down, the ballerina spoke. "Well then, who are you people?", the girl with the tutu asked, "Beats me.", the boy with the bandanna answered, "Yeah, me too.", the boy with the apron added, "Got me there.", the cowgirl said last.
Frisk was even more confused at that point, 'Why are they acting like this? It's like they forgot more than their time down here.', they thought before realizing something, 'They probably HAVE, maybe this reset was too much for their brains due to the amounts of magic they had used or have faced before!', they continued panicking. Frisk took a deep breath to calm down as the other six stood up and looked over themselves, trying to think this over. When everyone was done, Frisk turned back to them, only to see that the cowgirl found a loaded gun on her hip. "Why do I have a gun?", the cowgirl asked, "Careful with that thing, it's loaded!", Frisk replied with their eyes open, the cowgirl dropped the gun, "Who gives a CHILD a loaded gun?!", the cowgirl shouted (saying what we're all thinking), "I don't know!", Frisk shouted back, "Okay. Everybody, just calm down.", they continued, also trying to calm themself down. Once they all were calm, the boy with the bandanna spoke up. "Just tell us what's what, girly.", the orange kid demanded, Frisk sighed, "I will, but I must tell you I'm not a girl. I might look and sound like it, but I'm not.", they retorted, "So, you're a boy?", the girl with the ribbon asked, "I'm neither.", Frisk answered, "Oh.", the boy with the apron said blindly in surprise, "Could we just call you a 'they', then?", the boy with glasses asked, "Yes.", Frisk answered smiling slightly, "I didn't know that was possible.", the ballerina muttered.
"Okay, you just met me before we fell. So I at least know your names.", Frisk stated. They pointed to the others one at a time, "You're Faye...", they started while pointing at the girl with the ribbon, "You're Brayden...", they said while pointing at the boy with the bandanna, "You're Melody...", they said while pointing at the ballerina, "You're Percy...", they said while pointing at the boy with glasses, "You're Cody...", they said while pointing at the boy with the apron, "...And you're Clover.", they said while pointing at the cowgirl, "I can't tell you my name yet, because I don't like to say it.", they finished. Frisk now had their name associated with their past and it gave them very painful flashbacks, so they didn't even want it to be said. "Well, now what do we do?", Cody asked, "Just follow my lead.", Frisk answered. And with that, the kids went into the Underground.
Here we go, again...
