Elise Toudou 藤堂エリス

Lilica's younger sister. She spent time with Ken at school as part of her sister's plan to dig up information on the student council. Afterward, she states that Ken already knew why she was there and played with her anyway. Because of that, she has taken a liking to Ken, and she addresses him as "onii-sama". She is also quite mature and smart for her age, even managing to get a math problem right before Kurimu did.
