Souka

Souka is a supporting character in the anime That Time I Got Reincarnated as a Slime (Tensura). She is Gabiru's younger sister and the daughter of the Lizardman chieftain Abiru (also referred to as Abil in some sources).

Initially introduced as the unnamed captain of the Lizardmen tribe's guards, she appears as a green anthropomorphic lizard with violet hair, light armor, and a yellow scarf. She plays a key role during the Orc Disaster arc, helping rally her people and seeking aid from Rimuru Tempest to protect her tribe from her brother's misguided leadership and the invading forces.

After Rimuru names her "Souka" (meaning "Blue Flower"), she evolves into a Dragonewt, gaining a more humanoid appearance with dragon features like wings, horns, and a tail (which she can conceal), along with ninja-style attire that suits her role.

She becomes a loyal subordinate to Souei, joining his intelligence and shadow squad (often as his trusted second-in-command or leader of his team), where she excels in reconnaissance, spying, and combat missions for the nation of Tempest. In the main series, she's depicted as a dedicated, skilled warrior who admires Souei greatly as a mentor and superior.

In the spin-off The Slime Diaries, her personality gets more comedic spotlight, including her shy crush on Souei (which she downplays as pure admiration for his strength), leading to humorous teasing and awkward moments.

Overall, Souka is portrayed as competent, dutiful, and somewhat serious in the core anime storyline, with her evolution marking a significant growth in her abilities and position within Rimuru's growing alliance.
