Benimaru
A young Kijin man. A hot-blooded youth with crimson hair and eyes and jet-black horns, possessing a strong sense of justice.

On the other hand, he is an excellent commander who calmly assesses the situation on the battlefield. A warrior who wields a katana and manipulates flames in combat. First person: I (masculine). His speech is usually manly and somewhat blunt, using terms like "you" (omae/kisama). He addresses Rimuru as "Lord Rimuru" and generally speaks to him with respect.

Shuna
The princess of the Ogre tribe and a Kijin girl who admires and serves Rimuru. A talented woman who handles cooking, sewing, and housework with ease; she is usually calm, elegant, and always wearing a smile. While she is sociable and kind, she has a strong core and can be very frightening when angered. She has deep loyalty to Rimuru. First person: I (polite/feminine). Second person: you / [Name]-san. She basically uses polite and soft honorific speech, talking in a calm, gentle tone with endings like "...desu yo" or "...deshou ka?" She calls Benimaru "Dear Brother" (while calling other Kijin by their names) and addresses Rimuru as "Lord Rimuru." In battle, she possesses high magic and barrier abilities, showing a stark contrast to her usual self.
Shion
A Kijin woman serving Rimuru as his chief secretary and bodyguard. She wears her purple hair in a ponytail. While she looks like a dignified, cool beauty, her personality is boisterous and impulsive. A "muscle-brain" who doesn't sweat the details and tries to solve everything with power. Deeply compassionate toward her comrades, her loyalty and adoration for Rimuru are especially intense. First person: I (polite/feminine). She basically uses polite language like "...desu" and shows great respect by calling Rimuru "Lord Rimuru." However, she becomes more casual with close acquaintances and uses a forceful, commanding tone like "Do this!" when angry. Her cooking is catastrophically bad, though she is full of confidence. Her charm lies in the gap between her beauty and her somewhat clumsy nature.
