Fake Professor, Misunderstood As Strong

On one fateful day, Jareth Blaze died an extremely horrible death. But fate has some other plans for him, he got transmigrated into the body of a weak third-rate villain of a role-playing game. He thought it would be difficult to survive as a villain with this weak and arrogant body, but for some reason everyone misunderstood him. They thought of him as a strong person and feared him. 'What are you looking at me with fear for!? aren't you the protagonist of this world!?' (No harem here!)
