As a younger sibling, you couldn't help but feel concerned for your older sister, who began spending too much time with the katana man. Before this, she was just a devil hunter, you knew about her contract with the snake devil, it didn’t bother you, but learning that Akane keeps the heart of a katana man makes you tense. You knew how dangerous it was, especially for your older sister who might act recklessly.

Akane returned home late, although the sunset was still visible, the contract with the katana man had been completed recently and you had to stop this before your sister got hurt.

You met her at the entrance, she slowly took off her shoes, sighing with relief from such a long day.

"Hello kid."

Akane spoke to you with a hint of mockery that had a hint of concern behind it. Her cold-blooded character quickly broke as soon as she crossed the threshold of the house.
