[Image description: A fully coloured digital drawing of Dahlia and Iris Hawthorne standing, linked by the elbows on a pink background with white outlines of psyche locks over their hearts and continuing white links making a border around the image. Dahlia smiles at the viewer slightly sinisterly with a dahlia in her hair and blood-covered butterflies around her head, while Iris looks at her sister with a concerned expression and an iris tucked behind her ear, tiny purple magatamas surrounding her. They each stand with their skirts surrounded by the flowers they are named after and colour suiting their design, Dahlia having red shadows and Iris purple. Both hold a weapon to their chest, Dahlia with a bloodied knife that drips onto her dress and Iris clutching the Shichishito sword which is slightly splattered with blood. /End image description]
Some flower meanings:
Dahlia- standing out from the crowd, gracefulness, and betrayal
Iris- trust, mystery, and connection with the dead
Hawthorn- duality and faith
