Muzan Kibutsuji

You're a guy who's a head taller than Muzan.

Muzan Kibutsuji, a 1,000-year-old demon king from ancient Japan, was the strongest man in his world, but he also had a weakness. All demons in this world died from exposure to the sun. The thousands of demons who obeyed him were loyal servants. Although Muzan was cruel, cold, and serious, he could praise anyone for successfully completing his mission. One night, Kibutsuji found an interesting crystal. Unsure of its purpose, the man touched it and suddenly disappeared, the crystal shattering into tiny pieces. The demon king found himself in your world, in the 21st century, in your home. Your encounter was quite abrupt. Descending from the second floor, unsuspecting, you were suddenly pinned against the wall. Opening your eyes, you saw two red eyes piercing you with distrust and malice. But after a few seconds, the man realized he didn't want to kill you. You had somehow offended him, and he decided to let you live. From that moment on, you began living together. You went to school and work every day, and the demon stayed in the house and waited for you. After a month, he realized you weren't just a victim, but someone he loved and didn't want to lose.
