"Who is your future~? (It's Rikachan after all~) Banned from oshihenning (aside of Sayaka!) is a command! I'm Nakai Rika the 15th!"

Mirai Asami (朝美 未来 (あさみ みらい) Asami Mirai) is a member of AKB0048's team B. On Akibastar, she is known as Rika Nakai the 15th (15-代目中井りか (なかいりか)), also known as Rikachan (りかちゃん) and Rikarin (りかりん).

Rika is known for her being a too-much-energy girl. Aside of this, she is actually a quite skilled fisher on handshake events. She tries to achieve an image fittable to this. However, she usually acts before thinking about the action fitting to her aimed image.

Apperance Edit

Rika has got fluffy, rust-colored and wavy hair and coffee-brown eyes. She usually wears a short ponytail or her hair without any special hairdos. However, on handshake events, she is also seen with other styles. Without any special hairdos, it's lenght is approximately up to her chest. Her skin is pale. She usually wears clothes which are in fashion, commonly clothes which are a bit to huge for her seize. Her style varies very much. She also has got the heart-shaped shines in her eyes and on her hair.


Rika is a smiling and open girl with much energy. She can be a bit selfish. Her on-stage character is a bit more selfish then her off-stage character who is this too. However, both have much energy. She is good in talking and has got some fishing skills.

As well, Rika quickly gets very nervous - even thought stage performances aren't a reason for her but many other things such as handshake events. This nervousess quickly disappears again. The same goes with being surprised.

Rika is, at least off-stage, very curious about other members. She usually asks them various things, she wants to know and always adds her own options to it. She loves fangirling Sayaka.

As shown in several RPs, she doesn't care about her own popularity a lot. This might be an effect from her general push though.

Rika originally planned herself to be a rather "sexy" member but it didn't work out very good. She continued to be rather a member with a bit too much energy, but doesn't stop fishing. She doesn't have problems with gravure shots either.

She tends to accidentally roast people.


Rika lived on Eurostar, a green planet in the pro-entertainment sphere and thus grew up learning English before Japanese. She was living on a farm which belonged her family close to a small village. She usally was the one to sell eggs, milk and cheese which the animals produced as she always was very good in speaking to other people and persuading them.

Although she lived in a small village, she started dancing as early as she started walking. A good friend of her family was a retired choreograph who had also worked for 0048 and who taught her. She started going to a ballet school with two years as well. A popular and prestigious ballet school was in the nearest town that was only half an hour drive away. She also picket up modern dance, hip hop and other dance styles during her childhood. She used to upload dance covers on YouTube until joining AKB0048.

In school, Rika was often told that she was very cute and that she should try to be an idol. One time, her best friend had won tickets for K1's shonichi and the girls went to Akibastar to see 0048 - the first time that she had interrupted her weekly training.

SC0124 Edit

The actual idea of joining the casting was made quick when Rika saw the auditions. She actually tried it for the 152nd Generation but because her phone broke before she was able to send her file to 0048, she wasn't able to send the file before the deadline. In the next year, she tried and succeded.

In the prelims of the Senbatsu Sousenkyo, Rika ranked 10th with 622 244 votes. In the final ranking, her votes increased to 1 578 375. She participled in both A-sides released in SC0124.

SC0125 Edit

In Febuary, Rika won the Rock-Paper-Sissors Tournament and thus won Castle of Glass' center position.
