Note from the author DespairBreaker:

Warning, this AU will include mention of death, suicide, and gender dysphoria (suicide will NOT be explicitly drawn).

Thank you for understanding

"Remember, No Matter What You Do, No Matter If You Think We Are Immortal From That Star, We Will Eventually Have To Die Someday. That’s Why I Want You To Be Happy, Because Our Time Is Limited. Whether That Be One Day Or A Thousand Years"
– Chara Dreamirr


Haunted Hearts is a Deltarune/Undertale AU ask comic about Frisk and Chara erasing their world after many years of saving and resetting. Their last run was a genocide. They both then leave the erased world to go and haunt Kris, wanting to save them.

The AU is created by DespairBreaker and was first released on March 24, 2019 on Tumblr. The Deviantart adaptation started on January 11, 2020 and the Webtoons version started on April 21, 2020.

The worlds are not the same as those of Undertale or Deltarune, and are not meant to link the canon games, thus rules and logic are slightly different. Anything that happens past chapter 1 of Deltarune will not directly impact Haunted Hearts.

It comes in a variety of colors and designs. Though schools sell them, many go to stores dedicated to them since they last longer. Characters known to use them are Ruedof and Jay.
  • Writers Handle: Similar to the writers band, but instead of being a strap, the utensil holder is on a handle which is usually made of hard rubber or wood. This is most commonly used for monsters who can only write with their mouth. Characters known to use them are Lizz Kid.

Trivia[]

  • When the AU was being conceptualized, the names "Mending Hearts" and "Haunted Hearts" were both considered. The name "Haunted Hearts" was finally chosen since the word haunted is associated with ghosts and Frisk and Chara haunting Kris is an important part of the story. They also explained that "Hearts" in the title is purposely plural since the title has a double meaning, Frisk and Chara haunting Kris and also how all three are haunted by their past mistakes.[4]

  • It is known for the comic's blog title to change depending on what is going on in the comic. This is also shown in the deviant art's group motto
  • Many posts on the blog contains a secret message or a continuation of the dialogue shown in the URL.

  • The title "Haunted Hearts" is usually depicted with or part of an infinity symbol. The title as well has the A and D in "Haunted" have flowers in the middle of them, representing Frisk and Chara. The A in "Heart" having a red soul that represents Kris. This is all also reminiscent of the UNDERTALE title having a heart in the R.

In the DeviantArt version of the comic, the colors of the title at the end of each page is known to change colors or even signify that the page takes place in a Dream.
