Ari 。Ki

'''Ari. Ki''' is an American odorite duo of two real life sisters inspired by Tei☆in!. Their almost perfect synchronization and original choreography have inspired many fans, earning almost 3,000 subscribers on their YouTube channel. Ari is seen as the "masuline" figure of the group, while Ki is seen as the "feminine" one. Ari usually stands on the left while Ki always stands on the right so their order will be Ari Ki. They post to both Nico Nico Douga and YouTube.

On Nico Nico Douga, their original choreographies have made it into the top 100 ranking, such as their collaboration choreography with Light of LOVExLOVE WHISTLE. Amayu and Zensoku were inspired to cover Ari. Ki's choreography of Here and There, which made the number 1 ranking in the weekly odottemita category. On YouTube, their most popular original choreography is Dreamin Chuchu with over 31,000 views, choreographed to celebrate Valentine's Day and their most popular dance cover is Tei☆in's "Tell Your World" with over 55,000 views.

Ari. Ki often collaborated with Light before he graduated from CosStarDance.

In addition to their duets, Ari and Ki upload solo dance covers and freestyle videos. Occasionally, Ki uploads vlogs.
