Comic / Manga choice (Saber or Android 18) (Patreon)

So, I'll start making a comic from this month, and updates will be given to $10 tier weekly, what I want to know is, which idea you'd prefer for now.

Saber, after hearing Rin complain about her lack of money, goes out to find a job and receives a tempting offer from a stranger.

Android 18, defeated, offers her body to save her brother, Android 17.
