Nika Aoi

Nika Aoi (蒼井日夏, Aoi Nika) is a recurring character appearing in the anime and manga series, Beyblade Burst. Her current bey is King Kerbeus Knuckle Unite. She is the younger sister of Valt Aoi, twin sister of Toko Aoi, and daughter of Chiharu Aoi and Kento Aoi.

Appearance
Nika is a young schoolgirl with pink hair and orange eyes. She is always seen with pigtails, which are held up with two star-shaped hair bobbles. Nika wears orange overalls with a soft yellow shirt. Around her collar, she wears a red ribbon. Just like Toko, she has a prominent fang on the left side of her mouth.

In Turbo, Nika has grown taller and now wears a violet dress over a long-sleeved orange shirt with violet cuffs and one red ribbon on each sleeve. She still wears a red ribbon around her collar and two star-shaped bobbles on her pigtails. She also lost her prominent fang.

Personality
Due to being a child, Nika has an optimistic and playful personality. Alongside her twin brother Toko, they often playfully insult their brother Valt and the other Beigoma Academy BeyClub members during their training, especially when things aren't going as planned.

Despite this, Nika is shown to be very caring towards others and will openly show concern for them. Following Shu Kurenai's shoulder injury, Nika was very concerned for his well-being and felt guilty as she was the one who caused it. During Beyblade matches, Nika is also very vocal when cheering for a BeyClub member, such as Valt or Shu.

Nika is also shown to be very confident in her abilities as a Blader, but also burst into tears when she conceded a single point against Akio. Nonetheless, she quickly cheered up afterwards.
