"I need you to find Sanada Arata."
Apparently that power outage he and Daisuke had experienced the other day was his primary responsibility, and he had refused to be arrested and run off to the law. No one had any clue were he was and the police wouldn't give away where he lived. So they were to start from zero and Takumi's only advice was to "Talk to Mirei, she's probably at her shop next door. She always knows the best place to go."
So he did, and when he rang the old time phone he heard a voice that made him think of Hikari, even as they let out a comforting laugh.
"You'll need an EDEN account to get anywhere, he didn't think of that," she said. "So go there, Hudie Cafe is a good place to log in, and poke into places you aren't supposed to. Getting into trouble is a part of your role after all. As a group I mean."
"… What?"
She laughed and all he got in response was a dial tone.
Ken's eye twitched but he pulled out his phone anyway.
To Ikebukuro it was.
On the way there, he ran into a boy in a white hoodie. It didn't click at first, the teenager was running so fast he didn't even notice the smack, but once in the Hudie cafe, the obvious came to him.
Ken merely sighed to himself.
