Ciel was making sweets for her twin brother Rio in secret until he called Ciel by her fairy name which she also responded to.

“Kirarin.!!”

Ciel then walks to her twin brother Rio who she calls by his fairy name Pikario.

“What are you doing.?”

He just wanted to know what she was doing because he was just getting used to being back around his twin sister.

“You’re probably making sweets again right.?”

Ciel then nods her head and walks back into the room where she was making sweets for her twin brother until she finished while having the door closed.
