Volume 4:
Layla is introduced as third member of Sky’s team , Sky is a character who would have been the main character of this world if not for Noboru entering. Since Noboru's omni energy forcibly made him the main character of the world and allowed him to use the world's power system and adapt to it, Sky was sidelined. 
Layla faces natsumi and defeats her. Later, during the second void invasion, she is sent away with her classmates by Noboru. Subsequently, she is sent on a mission by Wind God Kaze to Whispering Winds Valley, where she learns about a cult that aims to free the void queen, Yami, which would bring forth untold destruction. This cult is known as the Disciples of Darkness, and they are located at the Wind Temple, where her ancestor, King Arthur Pendragon who came to be known as Arthur Skyward’s sword Excalubur is located. Which is one of the 4 relics.
They rush to confront Kuro Kagu, and Noboru assists them. They return with knowledge of the cult to the capital and inform Yumeko's father, Wind God Kaze, about it. He decides it's time to form an alliance against this cult and plans to go to Ignarock to establish an alliance that will unite all the lands.
Volume 5: Yumeko, Sky, and Layla are joined by her father, Wind God Kaze Hayashi, in going to Ignarock. When they arrive there, they are amazed by how different it is and meet with the Fire God, Ignis Braveheart, who agrees to the alliance. However, their meeting is interrupted by Ignis's own son, Kaen Braveheart, who is a follower of the Church of the Sun. This church was created by the ancestors to shift blame away to Aeritha, Yumeko's birthplace, for their humiliating defeat in the Elemental War. It was later confirmed that the ancestors blamed Aeritha because they knew Aquora, the nation that truly humiliated them, was a higher realm/kingdom and they couldn't harm them.
Yumeko, Layla, and Sky are tasked by Wind God Kaze to assist Fire General Kai in protecting the Braveheart Shield, one of the four relics of the world, located in Ignarock. On their way there, they notice a void invasion and disobey orders, deserting Fire General Kai to help. Sky transforms into Red Sky, a dual personality state fueled by his red wind aura, and tries to forcibly make Yumeko and Layla his women. Red Sky harbors intense hatred towards Sky, wanting everything Sky has, including Yumeko. Eventually, Noboru saves them by defeating Red Sky and awakening the real Sky. They then head to the temple and help protect the relic.
Later, they return with information about Noboru and discover that he helped defeat Kaen and the Rising Flames terrorist group that Kaen had created. At the end of the volume, Yumeko, Sky, and Layla are informed that Fire General Sky will accompany them to Aquora, a violent kingdom and realm that desires nothing more than war, but their ambitions are halted by Terravale, the strongest of the kingdoms.
