After Torako started coming home «late» in Anko's opinion, Anko began to suspect something was wrong.

One day, when Torako returned home at 8 pm, although she should have arrived an hour ago, Anko waited for some time before 10-20 minutes later going to her sister’s room and visiting her.

Anko walked up to Torako and smiled softly.

"Sister, why did you come home an hour earlier? I was worried about you."
