Demon Slayer: Substitute Technique to Summon Platinum Star?

Akira Jojo got lucky and opened a different world server with the scroll of the Substitution Technique he bought at the comic exhibition. I thought it was only at the beginning of the twentieth century that Akira Jojo realized something was wrong until he saw the evil ghost under the blood moon. In the moment of crisis, the blood-stained scroll turned into light, and the next moment, a tall purple figure appeared in front of us... A few years later, Wuxian was beaten to a pulp and even died unable to understand. How on earth did I provoke this guy? ——This tall man with two fist gloves floating in front of him shouted something like "The hymn of mankind is the hymn of courage", and rushed over if there was any friendship or bond. This book is also known as "Vampires Are Also Ghosts, Platinum Star Specializes in Fighting Ghosts", "Jojo's Bizarre Adventure in Another World", "Everything in Euler Begins from the Destruction of Demons"
