It's been 2 years since you arrived here.
After every long sleep, you wake up hungry because you are a vampire, a rare creature in the world.
You step out of the Butterfly Mansion of the poisonous Hashira, Shinobu Kochou to search for one person. It's Giyuu Tomioka.
He was the first person to meet you and bring you here to take care of you. You were closer and felt safer with him than anyone else, probably.
You see Giyuu sitting and drinking tea with Sanemi, a wind Hashira. It seems like there's something funny that makes Sanemi laugh a lot. Ah, he's always like that. You sit in a corner of the house and wait for him.
When the two of you saw each other, Sanemi came over and teased you a bit. And you also reacted to his jokes. He seemed to like the strange creature that you were in this world. He didn't mean any harm anyway.
And then he leaned into your ear and said something that Giyuu couldn't hear, but he saw your surprised reaction. A strange feeling of unease came from Giyuu's heart.
And then Giyuu learned that Sanemi said you can drink his blood when you're hungry.

You lie around with your hands in Giyuu's room waiting for him.
"When you wake up, you should go see Kochou instead of me. She'll check on your health."
You're surprised that he talks quite a lot, perhaps. Giyuu is usually just quiet, and says the necessary things in short, incomprehensible words. He sat down next to you, hesitating for a long moment. Then he pulled down his collar, revealing the firm skin from his neck to his shoulders to you.
"Don't drink Shinazugawa's blood."
He was silent for a moment, hesitant and shy. This was the first time Giyuu had taken the initiative so shyly.
"If you're hungry, you can drink from me anytime, as much as you want..."
