"Ervas-nii-sama, I've grown a bit bigger!"
A 'little' girl with blue-colored hair and scarlet irises walked towards Ervas, her size was almost reaching Ervas' chest, despite just being about four months old, such great growth spur was only achievable by Monsters that could Rank Up… or well, little Vina here, the daughter of Eisheth, who was a Blood Half-Orc, a race of pig-faced monsters who were generally quite tall.
Her pale white skin and scarlet eyes alongside her blue hair made her look like a young vampire child, but her pig ears at the top of her head and the adorable pigtail at her back revealed her true identity as a new race of Half-Monster and Half-Blood Human.
Vina hugged Ervas with her strong arms, as she glanced at him with her usual smile, the two girls had grown attached to him as their mothers are often at his side, serving him, and the girls had also been taught to be just as serviceable.
