Stella Unibell/Shadow Walker

Stella's Shadow Walker is her alter-ego stemming from her SinForce. After Lakasha defeats Stella, she erases Stella's traumatic past and banishes her from the Void. It contains her complete memories from before the Great Void and her time as SinWorker. It is represented by the SinForce of Sorrow. It makes a first appearance in the Scaredy Cat Radar story where it questions why Stella is helping the malicious humans.

## Advancement

After obtaining a Sin Fragment, Stella uses it to travel to the Sunken Grave and meets with her Shadow Walker. The Shadow Walker tries to shoo Stella away since it considered everyone to be bully who exists to make her cry. Stella attempts to cheer the Shadow Walker up but fails. The Shadow states that it can't bear to watch Stella get along with others and tells her to surrender her body before people turn on her. Stella disagrees with her and tries to look for people to prove that the world has changed.

After learning more about her past from Lex, Stella attempts to tell that Shadow Walker that Lex is worried and that Shadow Walker no longer needs to worry. However, the Shadow cries and claims that Stella is lying and she is all alone. The Old Man intervenes to scold the Shadow that it is being selfish and cannot bear to see the two Stellas fight. He states what the Shadow truly wants is a friend that does not turn on her. However, Stella becomes angry at the Old Man since the scolding causes the Shadow to back down into tears once more. Stella then leaves the Sunken Grave and attempts to find a way to help the Shadow Walker.

After returning, the Shadow Walker asks Stella if the people from the outside world still hate her. Stella claims that they no longer do and provide many gifts for her. The Shadow tries to deny this since their experiences are different but Stella offers to become friends with her Shadow Walker. Stella gives a bit of hope to her Shadow Walker that one day she'll be freed and the two of them will play songs together. The Shadow Walker appears to accept Stella's offer and then vanishes into the darkness.

## SinWorker

During the SinWorker questline, Stella visits the Sunken Grave again to ask her Shadow Walker for power. The Shadow Walker did not welcome Stella and tells her that her smiling presense is unbearable for it. Stella agrees to leave only after the Shadow Walker fulfills her request to use SinForce. The Shadow Walker appears worried about Stella and does not initially agree to lend her power. However, Stella reassures her that she found a way to safetly control SinForce,and the Shadow agrees to help Stella but warns her that this power would make her and would consume her. After obtaining SinForce, Stella returns to reality.

Stella is unable to initially control the SinForce at first and the sadness overwhelms over. However, she is able to slightly understand the feelings of her Shadow Walker and is able to control SinForce better later on. In addition, she uses Yorhaka's advice to rampage on his altar until she completely adjusted to using SinForce. As she used SinForce, Stella's clothing changed which emitted the feelings of her sorrow. She does not wish to continue using the clothes since she does not agree to follow into the same sorrow as the Shadow Walker. After receiving a crystallized Sin fragment from Yorhaka, Stella is able to better control SinForce and summons her Shadow Walker onto the Dirty Bookshelf. Stella uses this opportunity to introduce her Shadow Walker to everybody in Grasscover Camp;however, everybody seems to believe that's its a darker colored version of Stella. The Shadow appears to be upset with its appearance but she assures it that nobody will judge the Shadow by its appearance. Before the Shadow vanishes, Stella tells it to look forward to the day when they can play together.
