Synopsis[]
Following Fune's instructions to speak with her, Jin Sakai learns of her plan to capture a Mongol supply ship with enough to carry her raiders through the war.

It sounds like Fune is plotting another raid. I should see what she has planned.
― Jin's journal, before starting the Tale
Fune wants my help to relieve a Mongol ship of its supplies, at least, that's what she wants her crew to believe. In fact, she wants my help saving her daughter without a potential rival finding out and using it against her.
