Yuuna Oujou

She is a young woman with tanned skin and light-colored hair tied in a side ponytail on the right side. She wears a cardigan with a white collared shirt and striped necktie, modified Night Raven College pants (sometimes) under a pleated mini skirt, knee-length white socks, and loafer shoes. She also wears makeup, fake eyelashes, and light-colored lipstick. When she got a new smartphone from Crowley, she put it in a bright case with a Grim-like design and now wears it around her waist.

She has a cheerful and communicative personality. She enjoys fashion, and is dressed in Kogal style, which is a form of Gyaru. She is also very sociable. She enjoys taking photos with her smartphones or selfies with her friends. She took great care in her beauty and appearance. Yuuna is very bubbly, and loves talking to people, much like Kalim Al-Asim.

Yuuna is rather determined and rarely gets discouraged by things, and often tries her best at everything. Occasionally she can act a bit scatterbrained, but she's actually quite smart, and still peppy and easygoing.

She seems to have a habit of giving people nicknames, such as calling Grim, "Grimlin", Cater, "Catey", and Trey "Trey-pai".

A regular pastime for gyaru is (parapara), a dance performed mostly with hands, arms and legs; with hand, arm movements and gestures with legs going back and forth from left to right. When performed in a group, everyone should be evidently synchronized. It is mostly danced with Eurobeat music or covers of other songs but with the aforementioned Eurobeat remix.

One of the most famous parapara songs and its tagline, 'GET WILD & BE SEXY,' is synonymous with gyaru culture and was a famous Eurobeat song of the same name, by the group Eurocker-Girlz also abbreviated to E-Girlz. There are many songs that can be danced to parapara. Yuuna knows a lot about parapara and is willing to share the knowledge with others randomly or if they ask.

Decoden, also known as keitai art, is another gyaru-associated hobby that Yuuna participates actively in. Decoden is a compound of 'deco', a shortened form of decorative and 'den', a shortening of phone (denwa). Originating in Japan, decoden involves the decoration of mobile phones and other electronic devices with materials such as acrylic, rhinestones, Swarovski crystals, silicone, and polymer clay. Denwa decoration is often ostentatious and makes use of 3D motifs as well as media influences. Though older decoden were glued onto the electronic devices themselves; newer ones such as smartphones are most likely to use cases to display decoden.

Another collectors type hobby Yuuna has is having substantial amount of mobile phone charms in their possession to accessorize their mobile phones. Also, decoden has also been used for events. Acer Inc. held a decoden contest for the release of their Acer Aspire One netbook laptops. The contest involved three contestants presenting their respective decoden designs for the netbooks in addition to a popularity poll.

Yuuna likes scrapbooking.

Yuuna comes from a family of farmers and helped them when she could, but her aspiration lay in fashion - she wanted to be a fashion model for the fashion magazine she subscribed to. When she was about to go shopping, a black carriage crashed into her and she was transported to Twisted Wonderland.
