Nakano's men took the body into their custody and reassured Nakano by telling her that the girls were safe. All of these men were wearing the same type of clothes which were black coloured suit and they also looked the same as they were bald and had sunglasses accompanying them.
They also took care of the girls and drove them to the Science_Sector. At the end of the day, Nakano discovered that the headmistress had her connections with the Divine_Ones.
Aoi and Himari were a little bit terrified from today's incident. Akari was a mature woman and so, she had the ability to convert herself according to the situation. Yui had a dark past and the deaths she witnesses now, don't scare her even by an inch.
