Characters (up to B30)
These are the people you meet up to B30, using only what the game itself tells you. People from B31 on are left out to avoid spoilers.
Lily
The heroine. She fights with traps and goes down underground to look for her family, who disappeared after the earthquake. She uses traps made from her father's blueprints.
Mia
A member of Lily's family who calls Lily "big sister". She has been missing since the earthquake. Lily follows Mia's shoe and footprints found on the first floor. Clear B30 and you can meet her in the Living Room of Lily's House.
Father
He was making traps to keep beasts out of the fields, and used to say that a trap is the wisdom that lets the weak beat the big. Gordon makes traps from the blueprints he left. He has been missing since the earthquake.
Mother
Lily's mother. She has been missing since the earthquake.
Gordon
The village trap maker. He makes traps for Lily from Father's blueprints; hand him gems and he makes traps (the Trap Gacha). He used to be a hunter and knows a lot about beasts. After B8 he tells Lily about the cave.
The shopkeeper of the Armor Shop
The woman who runs the village shop (called the "item shop" in the game). She makes armor for Lily from whatever materials she has (the Armor Gacha). She is looking for her son and the dog Pochi that he took in.
Martha
The old fortune teller. Looking at her terminal, she tells Lily about the underground and the enemies. She also tells Lily that a beast that has been defeated is not dead: it returns to normal.
Pochi
A dog the shopkeeper's son took in. On B5 it appears as a huge beast with pale-glowing eyes. When it is defeated with traps, the light leaves it, it returns to its small self and runs off into the dark.
Silver Beast (boss of B30)
A silver beast that watched Lily from the dark below after she beat the boss of B10. It carried Mia's ribbon in its mouth. It stands in Lily's way on B30.
