zerukalo (cookie)
Voice of Saigyouji Yuyuko and Moriya Suwako in Kuso☆☆☆☆☆, Konpaku Youmu in Onsen☆, Yorigami Shion in Gorgonzola☆. Her appearance in Kuso☆☆☆☆☆ went basically completely unnoticed, was the breakout star in the completely unremarkable Onsen☆, and achieved peak popularity in Gorgonzola☆. She's gone by several names but settled on зеркало (mirror in Russian).
Started voice acting around 12 years old in 2013 but her frequent name changes made her blend in with the vast amount of other wannabes and didn't get any parts until 2015. Her appearance in Onsen☆ as the heterochromatic Youmu who digs the onsen with a combination shovel and pickaxe first started giving her fan art. This was then followed by her main role as Shion in Gorgonzola☆ where her pitiful appearance and role had people sympathize with her. This was also compounded by the discovery that when she was connected with one of her previous names that admitted she was living in government poverty housing when she first started looking for roles.
