Again, attractive yandere.
She and Riven aren't twins. Riven is thirteen/fourteen. Manami is twelve/eleven.
Her personality is cocky, clingy, and pretty stubborn. Her main inspiration for the non violent yandere thing came from Legally Blonde's song Positive.
So other than that, Manami has a thing for Todomomo son, August. Her friend, Kusmi, ran away so she's really protective of august. I think of her as Spinel from Steven Universe. Not the villain but after she got rejuvenated and stuff. She didn't wanna be left alone and stuff. That's Manami.
Her eyes are blue and her hair is brown. She speaks Spanish when she's pissed.
Did I do a good job making her look more like riven? killitrian ?
