- Examining herself in a mirror
- Wearing spats under her dress
- Hugging or holding up a yes (or no) pillow
- Holding her hands in a claw pose (with optional unenthusiastic "gao") - https://catbox.moe/c/t817mr
- Wearing Ptilopsis' outfit from Arknights (minus the headdress and gloves) - https://files.catbox.moe/w85vin.png

Significantly lewder suggestions:

- Lifting her dress, with anything explicit cut out of frame - https://files.catbox.moe/1fws9z.jpg
- Wearing a one-piece swimsuit that's gone ever so slightly transparent - i.e: https://twitter.com/Seic_Oh/status/1245541636546809856
- Getting uncharacteristically flustered when her dress is lifted by somebody else - https://twitter.com/99chocolove99/status/1160229201741398017
