Yokoyama Asuna (横山アスナ/요코야마 아 슈나) was a member of AKB0048's 155th generation

Asuna is also known as Aries(牡羊座/양자리) reason as it's her stage name. She is most recognized for being Top 12 on the show "First steps" in SC0125. She is also formerly recognized for being in a girl group called "Celestial Girls".

Asuna graduated from the idol group after receiving information that her former group would stay permanent after popular demand. Especially how dangerous AKB0048 concerts are.


Asuna is about 5'6.Her skin tone is white .How one can describe her hair is brown,thin,straight hair which it can reach up to her lower back.Originally,her hair was blonde,but she decided to permanently dye her hair brown at the age of fourteen .

Her eyes are the color of lime green

The kind of outfit's you would mostly see her wearing relaxing and feminine.

For her age,she'd seem to have less weight for a girl of her age, her body shape is like a toothpick,very skinny.As the standard beauty of Koreans.Her hips are seemingly curvy.


She kept her image since Celestial Girls was formed. She's feminine and girly.When she's on stage performing she seems elegant as her gestures shows on stage.


She has a sweet and friendly personality. She's very outgoing and likes to see the world with her own eyes .She likes to treat everyone as an equal rather than her feeling higher than someone. Everyone expects her to be elegant or quite .In reality,she loves to act silly and stupid, I mean, she's still a kid, let her have some fun.

When it comes to the position of main vocal, she won’t want to lose it to anyone, you could say that she's a bit selfish


Asuna was born in Akibastar,but at age 3 she and her family moved to Koreastar as her mother didn't quite feel right living in Akibastar.At the age of 6, Asuna loved cooking more than anything in the world. Her main focus was to become a world class chef.She had learned the basic cooking skills from her mother as her mother owns a bakery in Seoul.When Asuna was just about 8 years old her older sister Sakura left the family home to pursue her dreams in being a singer. She didn't know what to do,but immediately knew that if her unnie sister left to pursue her dreams in singing then she should pursue her dreams in being a chef. She enrolled in the Institute of Royal Cuisine, but as all student, she had to audition to be enrolled,most failed enrolling as they have high expectations, but unlike others. Asuna passed. From then on she continued her dreams in being a chef.


She eldest sister was becoming a rising star. She envied her sister. She always wondered what it must feel like to reach that kind of fame. Asuna's cooking skills grew better over the years as she was in the Institute. On August 22nd, Asuna heard that there was a reality TV show, First Steps that being brought back which was an idol survival show. She knew that this was her chance. Many people were shocked when she arrived to where the show would take place seeing as her eldest sister is quite famous,they questioned what would she bring to the table(show). After two months, Asuna was the highest girl who was always top 10 in the show.She gave everything she had to be on top 10,she made many friends and rivals on the show especially a new best friend she now has who's from Sebustar. When the final episode came,things took a plot twist. Many other girls improved a lot and Asuna went down from the last three episodes. When the results came, Asuna appeared to be Top 12. This outraged some fans,but Asuna quickly stated on social media that threatening and hurting the members will never solve anything and dislikes people who do that.

On that day she went to AKB0048's concert that was being held on Koreastar. Her sister thought the idea of bringing her to watch their concert to cheer her up and it did,though something inside her felt that it wasn't over her,but the beginning her her life.


It was announced (and heard by fans) that the girls who were ranked from 12-20 would have a chance to debut,but in another girl group. They would still be signed under World-G Entertainment,but they would have a 5 month contract and the girls who were most fan-favorite would have the opportunity to be in the group. On Jan 25th,the girls debuted as Celestial Girls. The girls took a rise in fame and popularity. Asuna knew what it felt like to be a singer and idol (not that much). When May came around. The girls had to say good bye to everything as their 5 month contract had ended as all goodbye concerts they had to say Good Bye,but was it there last under the spotlight ? Asuna didn't know what to do after,until she heard that there was an audition for AKB0048's 155th Generation. She took the chance the second she read it. She only hopes that she is given a second chance.She loved singing the same level as cooking.
