This is Kotone Kashiwagi from Tonari no Kashiwagi San. The character is very cute and quiet, however she is a wonderful artist too as well. This character was requested to be made and was made by Pyro with 4 pieces of fries. If you wish to have a suggestion of a character to be made, please add me on Discord of Koikatsu Party, Pyro with 4 pieces of fries is the username.
