I, the SSS-Level Blood Demon, Devour My Girlfriend at the Beginning

Traveling through Tokyo, Lu Fei awakens the SSS-level blood demon. Feed on strange demons, devour and evolve, and grow infinitely. Crack girlfriend? Swallowed. Bone demon best friend? Swallowed. Rat demon classmate? Swallowed. He originally wanted to develop in a low profile. As a result, Miori Aburaya, a fourth-level transcendent, became his teacher. Lu Fei said nothing - signed up to join the extraordinary organization. During the day, he hunts and interacts with strange monsters, and at night, he devours strange monsters and upgrades. Use magic potions to enhance the level of extraordinary beings, and use strange demons to feed the blood demon body. All strange monsters in Tokyo are his hunting ground. Miori Aburaya: "Damn it, let that blood demon escape again." Lu Fei smiled. Captain, I'm right next to you, but you never know.
