The game opens with a wedding between the main character and a woman named Toki, which is rudely interrupted by an attack. This brings out Toki’s meaner alter ego, Towa. After an undisclosed series of events, Toki finds herself flitting back and forth through the passage of time.
Makimono is a fortune teller who predicted the attack on the main character’s wedding, as shown in the opening of Tokitowa. Bikodo is the head of the assassin’s guild, who is introduced in a fight scene.
