This is the same head mold as the standard release SD girl Mimi and the old optional head F-13. The default eye size is 20mm. Since this had been a standard model, the head was available to all FCS locations upon release. She was then discontinued at Sumika locations on September 30th, 2020. Following the usual pattern, she was then discontinued from Tenshi no Sato and Tenshi no Mado on January 31st, 2022.
