"Seven"

The group looked up at undyne.

"Seven human souls and king asgore will become a god."

Kara held sans' hand.

"Six. That's how many souls we have so far. Do you understand? One of you will die, and when that happens..... But first, as is customary for those who have made it so far, let me tell you the tragic tale of our people. It all started when...."

"No, you know what?" She shouted, making the group jump. "SCREW IT! Why should I tell you that story.. WHEN YOU ARE ABOUT TO DIE?!"

Abigail shrieked, making Devon jump and grab her shoulder. "Calm down!" He hissed.

Undyne pulled of her helmet. And there she was, a fish- woman- monster with yellow slitted eyes.

"YOU! You lot are standing in the way of everybody's hopes and dreams! Prepare to fight!" Undyne drew a spear. "End guarde!"

Kara felt a pull from her soul. When she looked down, it was green. Undyne smirked and a spear materialised in her hand.

Warning: for the most part this book was very canon, but I will differ from how the actual fight works for this. I hope that clears any possible confusion.

Then, it was blow after blow. Trying to block was futile, her health was slowly draining. The others tried to stop her, but just ended up getting their health drained.

A spear impaled kara through the stomach before de-materialising. Kara choked in pain. Her health was 3/20.

"STOP IT!" sans yelled suddenly, right eye kicking into life. Naruto was lead on the floor in pain, his left eye glowed. Naruto jumped to his feet. Sans' hand glowed.

They both lunged.

Now undyne was the one defending herself. The force of attacks shook the cavern.

Debris fell. A large chunk hit Abigail on the head. She heard everyone cry out in shock as her vision faded to black...
