Iris Stylish-Sword Belzerg (ベルゼルグ・スタイリッシュ・ソード・アイリス), usually referred to as just Iris (アイリス), is the first princess of the Kingdom of Belzerg. She is also known by her undercover name Illis/Irene (イリス), granddaughter of a chirimen trader from the capital. This is the detailed version. But because it's detailed, it also means her information is a bit limited(some other parts of her is detailed—mostly about herself, but others are not—others refer to her extra information, ex: relationships, etc). source from: https://konosuba.fandom.com/wiki/Iris_Stylish-Sword_Belzerg
