Nobody has spoken of the knife, not even the one who made the guide, we have done something wrong xDD or no one has unlocked it, but I have the maximum points in everything and I have repeated all the events of the day with lucile,and there is no way
I really don't like step by steps, but:
>Have 35 Dep.
>Select "Misty"
>Select "Top"
>Select "Original"
>If you followed the previous steps, MC will say something about making the outfit "skimpier"
>Go to attic
>Interact with shiny thing (That's the knife) (left from yellow box)
>Go back to Lucile Cosplay Event (Next day if you already did it that day).
>MC will say to Lucile that he has something to make the outfit skimpier.
>Profit!
Optional steps:
>Git Gud
>fap fap fap fap...
>Give me moneys for drugs and hookers...
>Do not subscribe to pewdipie nor T-Series...
>Have a beautiful day!.
