- At first, she wanted Neviril so she can fly higher with her than anyone else, after hearing what Floe said "If you really like somebody, you want to kiss her even when you're not flying a Simoun". So appearently, she thinks that a lot of things are better if she likes her pair Neviril.
- One night, she sneaked to Neviril's room to sit in her bed, asking her to look at her and to go outside with her leaving her despairing memories behind, and to open the door together she gave her a kiss before being captured by Paraietta.

- She wants to fly with Neviril, believing the sky can make her wishes come true, but she can't fly in it without Neviril, except if Naviril wants her to pair with another Sibylla, she knows that she can fly if she's with her.
- On a dangerous flight paired with Mamina, she was a little nervous, but when she thought of Neviril, and when she reminded herself that she was going to fly with her, she felt more relaxed.
- The first time she saw Neviril, she thought that their meeting was fated, then cried, she didn't really understand why, she was so happy when she met her because she thought Neviril might come with her, she was sure they'd be going together, when she looked at her, she felt the same way she did when looking at the sky.
- She confessed her love to Aer, she loves her, so she thinks she can make it on her own, to grasp a hold of her own sky, and if Neviril care about her her sky too, they can fly together, even if they're not physically there with each other.
