I'm a Behemoth, an S-Ranked Monster, But Mistaken for a Cat, I Live as an Elf Girl's Pet, Vol. 5 (Manga): Volume 5

A dragon with a fire in her belly...for a bun in her oven! Stella--the former dragon turned cute girl--has joined the party! Though given that she charges full force at any enemy she sees, having this tomboy around might be more trouble than it's worth...especially after her totally one-sided love for Tama and jealousy toward Aria only grow stronger once she sees them getting all lovey-dovey. Meanwhile, a tantalizing personal request for the party's services arrives in recognition of all their recent achievements. Stella gets hyped up for her first real adventure--but none of them know what truly lies in store on this quest...!
