[ Akua is an odd one compared to most mortals, so her bland acceptance of his words is likely less surprising than her calling Hayame a friend. Really, having even friends is still... new to Akua, and Hayame is greatly...more heroic than most than she had ever really had the...pleasure of interacting with. Catherine had been the one to dally with heroes like the Kingfisher or the White Knight, whereas Akua... She was born and bred Villainy, down to her core. Villains didn't make friends — or hadn't, before the Calamities had come along — or it was at least rather unusual.

Doubly and triply so for Sahelians, whom were Old, Old evil.

She does not interrupt him, she listens carefully, reading between the lines. Like many, Sebastian was a survivor. He would not want an end to his existence any more than she wanted an end to hers, for most of them, they wanted to live. That was the whole point of the question of Meridian versus Zenith, wasn't it? There is a note of acceptance in her implied nod at his request. ]

I would do this. [ She would do it anyway but does not share that. One never negotiates from a less valuable position. To shatter a shard would put a target on her back, and Akua thinks Hayame has not considered this. ]

In exchange... I would think a gift of knowledge would be appropriate. Of your world's demons.
