MTL - Princess Medical Doctor - ~ 965 evil woman, she is reluctant

Liola—the best assassin in his world—has vowed to kill no more. He was being chased by an assassination organization when he accidentally dropped into a parallel universe: through a dimensional gate and into poor teenager Kaiser’s apartment. Instead of going to the government shelter for lost dimensional travelers, Liola and Kaiser wind up going to school together.

Liola has been trying his best to live the life of an ordinary person, but after certain things happen one after the other, he begins to realize that being an ordinary person could be harder than being an assassin.

The weak prince of an insignificant country, Davey. After becoming comatose, his soul escaped to a temple where the souls of heroes gathered.

He trained for a thousand years and has now returned as a max level hero!

“Just you guys wait, I’m gonna face you all head-on!”

The refreshing story of Davey’s royal life and revenge has just begun.

Born into a world of chaos and violence, young shapeshifter Rhishisikk struggles to survive. With the assistance of unlikely allies, he must learn to live among the most dangerous of monsters – human beings!

Back in 1998, an ordinary person who has been through, tired, cried, and fought, hopes to run down-to-earth and keep up with the trend of the times.
