Crossover: The Evolution of the Affection Index

This is absolutely the author's wildly imaginative idea, brimming with beautiful hopes for the great universe! I hear Hibari has acquired a blood-sucking creature. The technical term is vampire?! System notification: Contract signed. The honeymoon trip begins now. It ends once the pet's and owner's affection level is maxed out. A 1v1 transmigration adventure featuring a cute vampire x the Executioner (with the whole KHR cast along for the ride). And so, on a dark and windy moonlit night, a certain creature clutched its stomach. "Master, I'm hungry." System notification: The owner should provide food. ════════════════╮ [Below is a protest in the form of a conversation by some innocent bystanders]: ╰☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆ The KHR cast flipped the table. "Enough! Why are you dragging us into your honeymoon trip?!" System notification: Sorry, the System has crashed and cannot recognize your question! Everyone was speechless. This thing was absolutely doing it on purpose! A few things to know before reading, just a warning in case anyone with a weak heart wanders in~ 1.
