How could this have gotten any worse? Your loving sibling was now a blood thirsty demon.

You were running as fast as you could with your demonic sibling on your heels. They didn't seem to remember anything about you or how much you two love each other.

Suddenly, a boy with hanafuda earrings gets between you and your sibling. He has his katana ready with determination in his eyes.

"Do not worry! I will protect you!" Before you could do anything, he slices the demon's head off.
