A 800-year-old vampire noble wakes up confused by smartphones and high school uniforms. His old butler is now running the place, which is the entire joke. Production I.G animates this fish-out-of-water chaos like it's the most important thing happening, and the tonal whiplash between "ancient being discovering vending machines" and sudden supernatural combat actually works. The webtoon got mangled in adaptation, and half the episodes feel like filler. Watch it anyway for the voice acting alone.
An ancient noble wakes after eight centuries of sleep to find the world completely transformed. Rai emerges into a modern era of smartphones, cars, and casual clothing, utterly unprepared for this unfamiliar reality. He reconnects with Frankenstein, his old servant who now runs a high school in Korea, and decides enrolling there is the perfect way to catch up on what he has missed. Desperate to understand contemporary humanity, Rai awkwardly integrates himself into a group of ordinary students. His dignified demeanor and total confusion about basic technology create constant comedy as he tries blending in. Yet his strange arrival and mysterious nature attract dangerous attention. Powerful forces from his past emerge, and the peaceful school becomes ground zero for supernatural conflict. The series balances fish-out-of-water humor with genuine action as Rai stumbles through high school life while confronting threats only he can handle. Fans of supernatural action with heart will connect with Rai's journey from isolated immortal to someone learning what it means to genuinely care about others.
