Runo Sakaki

Runo is the daughter of and.

Design
Runo has aqua-green hair combed in a curvy spiral fashion, similar to her father but with the spikes wrapping around all the head and with the color of her mother. Over the forehead she has a blonde bang spiking upward similar to her mother's, but smaller, and with two thin sidetails suspended around her face. She has her father's light blue eyes, with a shape remiscent of both his parents.

Originally, her hair was more angular and colored light blue, but it was changed to avoid making her look too similar to Yugo.

Her usual outfit is a skin-tight pink riding suit (similar to 's) with green lines and orange pads over the breasts, shoulders, elbows, and knees; pink gloves, and orange heeled shoes.

Her is a custom model shaped like Yugo's, with blue circular body and yellow double-blade.

She has a red, built by her together with her parents, dubbed "Flaming Star".

Personality
Runo is a very energetic and always happy girl. But at the same time, she's tomboyish, as she really likes traditionally "male things", such as mechanics and electronics. As such, she's very good with motor vehicles and computers. She tends to spend time with both boys and girls of her age.

Much like her father, she's a bit of a glomper, sometimes invading others' personal space, but she does it calling others "bro" and "sis", and when she starts to know well someone, she learns how to not make them uncomfortable.

Etymology
Her name is a fusion of her parents' names (more specifically, Yugo's vowels and Rin's consonants).

Yugo and Rin
Runo loves greatly her parents, and idolizes her father's ing skills, hoping to become like him one day.

Rito Kurosaki
Runo and Rito are best friends, forming a typical "tomboy and girly girl" duo. When she's with her, Rito opens up more than with others, and is always amused by Runo's antics.

Rise
Despite her personality, Runo has a vitrolic relationship with the Fusion child, and she's often annoyed by his "trolling" attitude. If she's not happy, then he very probably just irked her. This is caused by a fragment of their fathers' sleeping inside them.

Yushi and Asuyu Sakaki
Runo is friendly with the Sakaki siblings as well, but she a bit closer to Asuyu, as she sometimes spends time together with Runo and Rito to do girly things, just like a trio of sisters.
