RIKA, who looks like a serious class president, has a completely opposite side as an otaku fangirl. She usually draws her own manga and has recently been active as a doujin artist. She's now scheduled to appear at a doujin event and is highly motivated for it. Her hesitant way of speaking, combined with her slightly unrefined appearance, is incredibly charming and captivates everyone who sees her. However, even the staff are shocked by her intensely aroused sexual desires.
