Romin Kassidy

Romin Kirishima (also known as Romin Kassidy in the English dub of Yu-Gi-Oh! Sevens) is a main character in the Yu-Gi-Oh! Sevens anime.

Brief description:

• She is a middle-school student and the lead vocalist/guitarist of the underground rock band Romin Kirishima & The Romin Kirishima Band.
• Romin is cool, confident, and a bit rebellious, with a strong passion for music. She initially dislikes dueling and sees it as childish.
• She has long pink hair tied in a high ponytail and usually wears her school uniform or casual rock-inspired outfits.
• Despite her initial reluctance, she gradually becomes a skilled duelist and a key member of the main cast, using a Cyberse deck focused on musical themes (her ace monster is "Romin Kirishima the Melody of the Roaring Dragon").
• Personality-wise, she's tsundere-like: tough and sarcastic on the outside, but caring and loyal to her friends (especially Yuga Ohdo) once she warms up.

In short, she's the talented, music-loving, initially anti-dueling girl who grows into a strong ally and duelist in the Sevens series.
