After decades of being sealed underground, monsters have returned to the surface world. However, you can't help but feel that they are hiding something. What happened to Chara, the first human said to have fallen into the underground? Curiously, you journey to Mt. Ebott, only to encounter something you never thought you'd see. Or someone: Chara. Chara is referred to as (they/them). Reader is referred to as either male or female, identified as (he/she). Rating: PG 14+ for (little) explicit language, violence and fantasy violence, and suggestive/sexual themes. Last edited 03/19/19, on indefinite hiatus. Thank you for reading. ♡

A heart, the universal symbol for love and the key holder of the box of feelings, why does a bloodthirsty killer suddenly obtain one after meeting an everyday girl such as yourself?
