Rimuru never imagined he would transmigrate into the body of a dying man.
If I was going to transmigrate, couldn't I at least get a better situation?
What kind of joke is it to end up in a body that's about to die?
With the mindset of a tabloid reporter, he said to the younger man connected to this body:
"I love you. If you can't accept that, just take it as a joke from your senior on his deathbed. Be good to your fiancee, okay..."
Then he transmigrated again... and became a slime... with a Great Sage.
Rimuru: "Wait, this seems kind of familiar..."
Isn't this the anime his little sister is watching?
After finally becoming friends with the Beast King, Rimuru never would have guessed that he would transmigrate into a game again.
He and his companions built the Great Tomb of Nazarick,
And when the game was about to shut down, Rimuru thought he would disappear along with the game data.
But instead, he transmigrated again... and "sort of" returned to the world of Slime.
Looking at his panicked friend Momonga, Rimuru remained perfectly calm.
He reassured him:
"It's fine. Relax. I'm used to this."
