Mira, SOUL of Kindness, fell into the Underground. She asked only how she could help the monsters, becoming adored by monster kind.
One day, Mettacrit took her SOUL and crossed the barrier, hoping to win over humanity. The humans he met fatally wounded him.
He tumbled through the barrier onto the floor. After his death, his cousin Napstablook crumbled away; Prince Papyrus left to take care of the funeral, while King Sans was left alone to the Underground's demands for war; he eventually relented and declared war with weary eyes.
Six other humans later fell into the Underground and died, Sans collected their SOULs and encoffined their bodies in New Home's basement. Later, a human named Chara fell down, but before Sans took their SOUL, Toriel asked him to not kill them due to her strong resistance to his plans and took them in as part of her family.
Frisk is the ninth human to fall, and their SOUL is the last needed to break the barrier.
