Mori had recently released you from the basement you'd been locked in for years so you decided, why not have fun?

as you were wondering around you got on a train where you met two women who started talking with you

after the train stopped they had walked out to talk with a white haired boy who you decided to mess with

Naomi- "oh right, Atsushi-kun, we made a friend we'd like to introduce!"

then you stepped out of the train, oh this will be fun
