Mitsurugi

A Divine Sword wielder.

Mitsurugi's strength and ability exceed even what one might expect given the effects of her weapon. She can run up a mountain trail without so much as losing her breath, and her competence with the sword impresses even her senior colleagues.

Although Len could've sworn looked like she was just shy of thirty, Mitsurugi is actually well in her forties.

Spoiler

Unexpectedly given her personality, she likes buying teddy bears.
