Tearlaments Merrli is a mermaid/siren-themed duel monster in the Starfrost storyline. She is the youngest of the Tearlaments. Like her sisters, she wears a tiara and has grey hair.
Unlike in the OCG and TCG, where she is limited, she is currently banned in Yu-Gi-Oh! Master Duel. This caused a rivalry between Laundry Dragonmaid and Merrli to spark up, due to their similar "mill three cards" effects.
