Kiken Akutagawa(Akutagawa's little sister)

Atsushi glanced at down, there was a young girl with long black hair with stipes of white hair tugging at his shirt.
"Excuse me. I got separated from my siblings can you help me find them?" Asked the girl. Atsushi nodded while scanning the large crowd of people looking for other people who resembled the child. He didn't see anyone.
After a bit of searching with no leads to where her parents and siblings were Atsushi decided to bring the young girl back to the agency so the others could help.
