She is a girl who is good at household chores and has an extremely worried personality with a slight brother complex. She has a glamor constitution and is characterized by a red-haired ponytail. Her basic combat tactics deal with all her attributes of attack magic while fighting with her bare hands, all with an "elder sister" when casting her magic. She can easily handle heavy weapons, but she can't equip them because she's just trying them out and she's too powerful to destroy them, regardless of the durability of any weapon.

When his younger brother Asahi was in a car accident, he was worried about the word "another world" muttered by the sickbed Asahi and began to hypothesize that the soul of Asahi was in a different world. He struck his head several times and attempted suicide to the extent of a crush, and his soul was invited to a different world with the morning sun. As soon as he arrives in a different world, he gains cheat-class power that pushes all stats out of the limit and can defeat the large monster Wyvern with just one blow.

When he first came to another world, he dressed in skimpy outfits from school uniforms after the Wyvern subjugation. Because of his personality, he turns hostility toward those who try to hurt Asahi and loses or buys a large amount of recovery medicine at an item store just in case. From the encounter with the Six Demon Lords, Kirmaria, he fought a fierce battle more than equal and won, and after that, he took a casual attitude toward Kirmaria. She is strong against occults such as evil spirits and is resistant to unfavorable anomalous stats. Joined the party of the Super Asahi Corps from episode 36, and devised the name of the clan formation as a bond between friends.
