Sheila Grandsley

Sheila Glanzudlii  (シーラ・グランズドリィ, Shīra Guransudorī) is the adoptive mother of Lay Glanzudlii.

Personality
She is cheerful, gentle and careful.

History
Born as the child of a demon from the royal faction and a spirit mother, Sheila was abandoned by her father because of her mixed-parentage, something that could tarnish his reputation due to the importance of blood purity to the royal faction. Because of this, she was unable to leave Lay, whom his family left to die in the streets. She took him home and gave him a meal to eat, incurring the fury of the Yesla family, who threatened her if she ever did it again. Nevertheless, Sheila didn't kick him out and the two of them moved to a city where they couldn't reach them.

She raised him like her own son despite having a weak constitution. Because she was a half-demon half-spirit, her magic power and root began weakening until she developed spirit disease, a condition that half-demons half-spirits face when their traditions and rumors become forgotten or cease to be known. The two visited many clinics until they arrived at the Lognorth Magic Clinic, which put her condition into remission, seemingly able to help her. However, in exchange for helping Sheila, Lay was forced to join the royal faction against Anos Voldigoad in the Magic Sword Tournament and let them implant a magical device inside his body.

Magic Sword Tournament Arc
When Anos and Misa visited the clinic, Sheila woke up for the first time in a long time. Although she seemed to be comatose, she was actually conscious all this time, and was able to recognize Anos from the stories Lay told her about. She told him what she knew about her condition and what she overheard from the doctor, giving the boy a better understanding of her condition. Sheila didn't know how, but a bit of her power returned to her, waking her up. And she used this chance to tell Anos about Lay and asks him to fight Lay with all he has.

Anos then invented a new magic to help Sheila, allowing Misa to change and transfer parts of her traditions to Sheila. Although her condition got worse, and she couldn't speak anymore and her body began fading away, she slowly recovered once the traditions settled in. When Lay returned to the clinic, she was able to tell him to live freely and that she will always be by his side, before falling in a deep slumber and leaving Lay in tears.

After Anos defeated Lay in the tournament, they were sent to another dimension, where Melheis planned on ambushing Anos. However, Lay didn't die after being defeated by Anos and helps him against Melheis, causing the latter to reveal that he took Sheila hostage and that by breaking several gems, he can end her existence as a spirit. But both Anos and Lay told Melheis that he could kill her, creating enough confusion for Lay to break in to the dimension where she was held at. Melheis then fires Beno Yeven at Lay and his mom to force Anos to divert more magic power to protect the two. This causes Lay to ask Anos for a sword instead, which he uses to slash away the magic fired upon them, but no matter how much Lay cuts away, it keeps returning.

Lay, who was planning on giving up and entrusting his mom to Anos, was encouraged by Sheila to continue fighting. Sheila then used all her remaining power to return to her true body, a powerful spirit sword. The two reminiscence about the time when Lay sliced a pot with a knife, before Lay destroys Beno Yeven using his mother's sword, resulting in Sheila fading away as she tells him the she loves him. Once the battle was over and they were back in the Arena, Anos reveals that Sheila's spirit disease was cured and he uses Ingal to resurrect her. A few minutes ago, Anos declared in his victory speech that the sword his dad forged using heart and hopes had the same strength as a magic sword. He deduced from everything that had happened so far that the rumors that formed Sheila's source were: something other than magic residing in a sword that was forged by a true craftsman. With his victory over Lay, people who were spectating the tournament across Dilhaide starting believing in this, which made Sheila's rumors well known. Sheila thanks Anos and reunites with Lay.

Abilities

 * True Form: Being a half-spirit, Sheila has temporary body and a much powerful true body, which in her case is a spirit sword. The spirit sword is strong enough to cut Beno Yeven, the very same magic that split the world into four.

Lay Glanzudlii
Because her own father abandoned her as well, Sheila couldn't bring herself to abandon Lay, who was just a child. She then raised him and treated him like her own son, to the point of wanting to die from her spirit disease instead of holding him down.

Trivia

 * Sheila's true body resembles Anos' Diamond Iron Sword because the true body of a spirit embodies their rumors and traditions. In the minds of the audience, they had a clear image of a sword that was forged by a master craftsman not by using magic but by his heart. They were looking at Anos' sword so Sheila’s appearance became that of his sword.
