Hannei is unaware of any internal sleuthing or unwanted presences lingering. Instead, she smiles.

“I’m happy to help!” She lightly taps her her toe against her other heel. “And um, thanks for talking, I’m sure this whole situation with the tapes is… weird” she doesn’t know what was on the tape Akechi got but he looked frazzled when she saw him. So she can’t help but wonder what else could be seen on these tapes.
She wonders if anyone got one of hers.
She isn’t sure if she wants that to happen or not.
“But I like talking with you! You’re cool” Kou is pretty cool. And maybe it’s her curiosity but she does want to get to know him more.
He’s the only Kou it seems, like she’s the only hannei.
