The main character of this work. She is 17 years old. The adventurer's job is a sorcerer. She is a girl who is good at household chores and has an extremely worried personality with a slight brother complex. She has a glamorous 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, she 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. She 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 she arrives in a different world, she gains cheat-class power that pushes all stats out of the limit and can defeat the large monster Wyvern with just one blow.

When she first came to another world, she dressed in skimpy outfits from school uniforms after the Wyvern subjugation. Because of his personality, she 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, Kilmaria, fought a fierce battle more than equal and won, and after that, she took a casual attitude toward Kirmaria. She is strong against occults' such as evil spirits and is resistant to unfavorable anomalous stats. Joined the Super Asahi Corps party from episode 36 (*Manga*), and devised the name of the clan formation as a bond between friends.

*Size*: 92, 58, 85 from the top to bottom

### Abilities

All the stats are square and translucent, but Maya's stats are generally darker than others. Its darkness is similar to the color in the graph displayed in my status. The color of my heptagon graph is exactly the same as the color of Maya's entire status screen. All the numbers are too high to fit on the screen. She is very talented in either music or martial arts.

She's a strong Brocon and she loses her cool when it comes to Asahi. Under the hypothesis that her brother, who is in a coma, is in another world, he succeeds in her transferring her soul by hitting her head against the wall and losing consciousness. Maya's strong attachment to his Little Brother Asahi, she can sense when Asahi is a dangerous situation or when Asahi is not close to Maya's area. Maya is also a great cook because she wants Asahi to eat delicious food.

 「Big Sister Flare of Rage」

Her status in another world is a cheat class that far exceeds the upper limit. Maya has a high resistance of mental attack (Possession, Hypnosis, etc) giving her complete resistance because of her love to Asahi. Because of being transferred into the new world Maya's senses are being heightened enough that she can sense the malicious aura of a certain person. She can defeat Kilmaria, that category as one of the six most powerful Demon lords.
