Iris Stylish-Sword Belzerg

Iris Stylish-Sword Belzerg (often just called Iris) is the first princess of the Kingdom of Belzerg in KonoSuba: God's Blessing on This Wonderful World!.

She's a young girl (around 12–13 years old) with long blonde hair, blue eyes, and a refined, delicate appearance that gives her an air of elegance and nobility. Despite her sheltered royal upbringing and polite, formal demeanor in public, Iris has a tomboyish, adventurous side—she's deeply curious about the outside world, commoner life, and adventure stories.

She's exceptionally strong for her age (thanks to her royal lineage and high stats), highly skilled in swordsmanship and combat magic, and wields powerful abilities and a legendary sword. She forms a close, sibling-like bond with Kazuma (whom she calls "Onii-sama" or big brother), admiring his tales and personality.
