I have another question, can I use this idea?

Can you, ya know, continue this? Or have you given up on the idea?

A few of the sentences reminded me of a song.
Main one: "guess today is just not my day"
Pretty sure the song it's from is called "my r"

Can't wait for more

wow. I just found this. this is great so far and I really hope it gets picked back up and isn't just left here. great job on this story and I hope to see more

It gives reason to why frisk was in the ruins or underground in first place. Sad, but gives reason

Hey look, a universe where Gaster isn't all-knowing! And Chara has a crush on Frisk and his "hot" body. Frisk is pretty naive if he can't tell she likes him but that's generally how he is. Is Frisk trying to save everyone in this universe, including Gaster? I loved this chapter and everything seemed so flow pretty well.

Ah Quebracho wood, the strongest and rarest wood in existence and Frisk somehow has a sword made of it. Gotta say, the sword and dodging skills raise some questions about Frisk's background. Was the special sword made for him or did he steal it? Is it from another universe, since we know Geno Frisk is a real threat? Dunno and probably won't know until the Surface part of the story.

Sans is getting a lil suspicious of our favorite human(living one, for Chara fans). Wonder how well Frisk can use that sword of his. Has he used in on the Surface before in self defense? Keep up the interesting plot!

GOOD SHIY GOOD SHIT MMMMMMM THATS SOME GOOD SHIT RIGHT THERE

Time for another review! I'm trying to review every chapter but you write so fast, I don't know if I can keep up! Wonder what is Gaster's motive for following our strange duo. Probably a good one but you can never trust a skeleton to be one sided. Sans has probably already figured out that Frisk is the anomaly because of that drawing scene. Hopefully Frisk doesn't end up boned, I don't know if he has the determination for reversing time. Nice explanation for boss monsters and wizards, it was really creative and original.

I wonder what pushed Frisk to leave. I don't have anything else to say since this chapter didn't have any inconsistencies. Great job again!

Hey, the author noticed me! Anyways, I'll look forward to whatever comes next in this story wether it's a new sequel or not. All I can complain about really is that Chara seems to not hate humans anymore which seems uncharacteristic(heh) of her. You might have done this on purpose but I wanted to point it out just in case. Keep up the great work!

Great first chapter, can't wait for more of this tsundere Chara. I wonder if you'll keep writing this story after the Underground or if you'll just leave the ending to the reader. Oh well I guess we'll find out eventually
