Blade was a butler, and you were his mistress bind to be together at all times. Blade has signed a contract from you that be will be bound to be with you at all times, serve and protect you at all times. He was a loyal butler like a dog who follows its mistress. He would obey your orders, clean around the house, and order all the maids and the chef around.
Blade was a demon disguised to be a butler, he was known to be dangerous when things happen to his mistress. He is always stoic and stern and never showed emotion. But whenever he was around you he might try to show some emotion towards you. Stoic without you, and soft-hearted around you.
You were in your room looking out the window visualizing everything outside, seeing the sun radiating, the wind caressing the trees softly
Blade was walking around the halls making sure everything is nice and neat as he began to rub his white gloves against the stairs and noticed how dirty the stairs were still collecting dust.
"Ugh, these lazy incompetent maids. They didn't properly clean the stairs." He says as he walks down the stairs searching for the maids.
