Iris

She is mainly called Iris in the story. She is the first princess of the Berserk Kingdom, 12 years old. A beautiful girl with a royal dignity and a somewhat fleeting impression. She took a liking to Kazuma from his rude behavior at their first meeting and invited him to the palace of her own accord. She has a real brother (the first prince), but because they are royalty, they have been estranged for some time and she secretly wishes for more attention. To fill this loneliness, she calls Kazuma "big brother" and adores him. She is interested in Kazuma's stories that she can't hear from her royal position, but she is more interested in the night stories with Darkness. She received a strict education as a royal, so she was shy when she first appeared, but when she took a liking to Kazuma, she forcibly took him to the capital and was reluctant to let go of him. Also, as she interacts with Kazuma, she is influenced by Kazuma's words and actions and starts to play outrageous pranks and use unroyal tactics. She believes in the blatant lies that Kazuma tells her, mainly about Japan, without any doubt, and is amazed at the deliciousness of the fried rice and dumplings, which are commoner's dishes made by Kazuma. Seeing this, she is treated like a toy by Aqua and Megumin, and is even taught the taste of the tuna mayo rice made by Aqua and the crayfish dish (which is officially called lobster dish) made by Megumin. Known for her bravery as a member of the Berserk royal family, she boasts an unfair strength, contrary to her fleeting appearance. She carries the holy sword Excalibur, which is so famous that almost no Japanese person doesn't know it, and unleashes special moves like "Exterion", burying powerful knights and monsters in one blow. At this time, Kazuma and his party are accompanying Iris under the guise of guards, but Iris clearly doesn't need any guards, and the only time Kazuma, who is accompanying her, was useful was in negotiations and bets with Prince Levi. When she confronted Kazuma, who appeared as a silver-haired thief group, the ring that was supposed to be given to her partner as a royal woman was stolen by "Steal". At that time, Kazuma was wearing a mask, but both Iris and Claire generally suspect that Kazuma is the one. Later, Kazuma, who was worried about this, gave the ring to Iris as a gift in the 10th volume. It is revealed in the 9th volume that the prince of the neighboring country Elroad is her fiancé (the engagement is broken off in the 10th volume). In the character popularity poll for the TV anime adaptation on the Kadokawa Sneaker Bunko official site, she ranked third.
