Tsuzuki eats demons. They're not as tasty as pastry, but sometimes they leave him pretty gifts, dark wings and sharp teeth. He admires the gifts, then puts them away for later use. Hisoka likes when they can blend in and attack without warning.
Then a demon comes to Tsuzuki with purple eyes, wearing his own face, and says, "Asato."
"Who are you?" he asks, though the smell tells him.
"Your sire. You've done very well, but--"
"We share blood."
The demon frowns, says impatiently, "Yes."
"Share your blood with me." Tsuzuki strikes.
It's an exhilirating match; the blood, unexpectedly sweet.
