The garden, hm...? A good place as any to talk. Pity there aren't any roses, now that would be especially thematic.

[Flippant reference to the mystery that she once struggled to solve with Kuro (and eventually reached the solution of while refusing to give her any more hints than were already in the text), Yasu follows after her.

Once they reach the garden, Yasu stands amidst the illusory butterflies for a moment, perfectly still as they crawl across her and alight on her arms. It almost seems like she's the hologram, and that the butterflies are real.

The only motion that betrays her is the slight trembling in her hands.

Then, the moment passes, and she flicks a wax-sealed envelope (if nothing else, Beatrice's appreciation for dramatics is something that Yasu greatly admires) out of her sleeve and tosses it at Kuro.]

If anybody deserves to know my secrets, it's you. There always needs to be a piece that can counter even the strongest play, and there are none more suitable than you, partner.

[She's quiet. The bravado in her inflection is even more hollow than usual.]

Just know that once you open that, there's no going back.
