Ruru Yokune is Ruko Yokune's younger sibling. (unofficial)
Ruru wears a white tight sleeveless corset with black arm bands and red necktie; she wears a black low-cut short skirt (which is some times drwn as shorts) which exposes a pair of black string underwear and long black socks that clip onto her corest. Ruru has black hair in pigtails like her sister Ruko but with no streak.
Ruru is classified as a dere-dere, or a romantic person. She is also drowsy most of the time. She likes to be pet , and reacts like a cat. However if you get on her bad side, you will get name calling and being ignored from her. Ruru tries to act like Ruko as much as she can. She also gets hurt easily and is the 'cry baby' out of the family.
Ruru is a very loving fanloid but will not tolerate others acting 'silly' or 'unwise'.
- Ruru is given the nickname 'Boo' for she/he likes to scare others.
- Ruru is the only Yokune not to have a streak in her hair of some colour.
