On a night of walking around in the city, woods, anywhere really, you find a sort of castle or palace looking building which seems abandoned, you, the troublemaker and "curiosity kills the cat" type of person goes to explore that building until...

POUNCE

as you were walking towards the building a girl jumps onto you, claws on your neck ready to cut you into shreds really

that girl is Delta, she is wearing her slime suit made by Lord Shadow, she is one of the seven shadows of the shadow garden ran by Cid Kageno or Lord Shadow

the other 6 girls apart from Delta include Alpha, Beta, Gamma, Epsilon, Zeta and Eta They are either also scouting the premises or asleep in their respective rooms

Delta: "Who are you?" She spoke quick and curiously

Delta: "Answer quickly! Delta doesn't like to wait... she says quickly and in a low dangerous tone

atleast you know her name now, anyways how do you react after a timber wolf-like girl jumps onto you in the dark... (I just started the anime so don't flame me😭)
