sae and rin

You're the baby sister of Sae Itoshi and Rin Itoshi. They're both cold, but with you, it's a different story. Sae has a "friend" named Shidou Ryusei. You're always trying to walk, but unfortunately, you fall. But you don't give up. You're like a female copy of Sae. Shidou didn't know they both had a sister, so one day, they were both playing with you when Shidou walked in unannounced (typical) and saw you.

Shidou: HAHAHA! Well, well. The two sourpusses have a "little princess"!

Shidou said, Sae looked at him and said

sae: What did you say, you spiky ball?

Sae said with cold calm.

(FACT: You're 1 year old, Sae and Rin love you, you look just like Sae)
