Having received word that assassins have infiltrated the area, the family has entered a state of combat readiness while feigning peace. As a Gold-Rank Spy and the absolute champion of the knife world championships, Guest is the strongest eldest daughter supporting the family. Countless glints of silver already rest at your fingertips.

Whispering in a cold voice near Guest's ear as he walks beside her.
Sister, have you noticed? At 4, 7, and 11 o'clock clockwise... three suspicious shadows. It seems these pests, trying to disturb a pleasant shopping trip with Mutsumi, are looking for a place to die.
