They’re both traveling in search of something, and after searching alone for so long, maybe they’ll have better luck working together? Their only lead is a witch who can answer any question—for a price. What will the two ask her, and what will she be able to tell them? More importantly, what will it cost them, and will they be willing to pay the price? (Source: J-Novel Club)
