In episode 4, we learn that Akiko is the Armed Detective Agency's doctor, when she's healing Junichirou Tanizaki.
Just when she's about to start healing him, she starts taking off her shirt, and though Tanizaki appears to be dreading what's about to go down, she has a grin on her face:
That suggested, to me, that she was about to take some sort of sexual pleasure from what's about to go down.
Then the scene switches to the next room, where Atsushi and Kunikida are, and it sounds like Tanizaki is not really enjoying himself:
But then the noise subsides, and he sighs in what seems like a pleasurable way:
So it made it look like, to me, he was suffering for a while, but ends up taking some kind of pleasure from the process too, like Akiko appeared to be about to take herself.
This section from Akiko's page on the anime's Wikia says:
Akiko is named after a feminist pacifist poet whose work was considered controversial in her time for portraying and encouraging female sexuality.
So, basically, how exactly does Akiko's ability work? What does she actually do to heal someone?
It does have some sort of sexual connotation, given the trivia in the Wikia page, right?
Has the manga shed some more light on her ability? Or has maybe the author revealed anything in any other way?
