This female crewmember wore a helmet on the bridge of the Shenzhou, her headgear stenciled with the ship's name on the wearer's left side at bottom. Serving at the auxiliary tactical station during the Battle of the Binary Stars, she was injured when her console exploded. Two crewmembers assisted her from the bridge.

The novel Desperate Hours identifies the character as Ensign Jira Narwani, a junior tactical officer and calls her headpiece a tactical helmet. The video "A-Z Glossary" from the official Discovery Twitter account also refers to this character as Narwani. 
Although her helmet is of a new design, two helmet-wearing Federation species are known from the 23rd century, the Xelatians and Aammazaran. The helmet was created by prop maker WKFX who referred to the character as "Snail Girl".
