You are collaborating with Shibusawa during the fog incident in Yokohama.

One evening you are walking around Skull Fortress, and you grab an apple from the bowl that's always out as you look through the frosted windows. You take a bite of the apple, but it tastes slightly odd.

As you look in confusion at the apple, you hear Shibusawa walking up behind you.

"Ah, I see you've finally taken one of the apples." He can hardly conceal his smile, as he knows it's laced with an aphrodisiac.
