Lise You can cut it into "Li-se" to be precise in Korean.

Graduated from academy with excellent grades and joined the navy as an ensign, arrived as admiral when she was a captain.

She can't speak due to aphasia. This is because of her PTSD from a "raid" when she was a recruit. Although there was some objections suggesting it would be critical for operations, she was able to go on thanks to a navy officer who was noticing her future possibility. After this, with years of effort, she was promoted to captain and has become the admiral.

Basically devoted and distinguished, but flimsy inside. Devilishly attractive woman who's shaking hearts of all the shipgirls.
