Shadow Monarch in Tensura

Chapter 65: Chapter 65: New Ultimate Skill

"Ekmm..." I fake coughed, scratched the back of my head, and saw Rimuru looking at me, "I was slightly bored, and after I saw you eat Veldora, I decided to have some fun pretending to be your son."

Rimuru, whose [Mimicry] skill started working again after almost five hours, deadpanned, "How is pretending to be my son supposed to be fun?"

"There wasn't anything new and exciting over the years, and when I was about to visit Veldora, I saw an intelligent slime, so I kept an eye on you. Then you got a human form, so I decided to pull a small prank."

Rimuru was silent and looked at me for what seemed like hours. Why do I feel like a kid who's about to be scolded?

"It seems I did a bad job as a father, so as your punishment, I'll be taking all the mangas and novels until further notice," He said, standing up.

"Wait! You know I'm not really your son, right!?" I asked.

"Oh, but you pretended to be one, so I will treat you like one," He said, and I saw the hundreds of mangas disappear into Gluttony's stomach.

"My manga..." I cried...

...

..

.

A few hours passed after I lost all my mangas and novels, and I saw Rimuru thinking about what I'd said, "Wait, so you, Ashborn, and Milim are Demon Lords. Could you tell me something about the others? You know, after me treating you like a son for so long, you could at least do that." He tried to guilt-trip me into giving him some information.

"While I can't tell you much about the other Demon Lords, you should know that at your current level, even the weakest one is stronger than you," I said, which was true at the moment Rimuru would be considered Special-A Class by the future Tempest Rankin System, "Oh and Ashborn and I are the same person."

"Huh?" His eyes widened slightly, "So you are the Ashborn that Veldora has been talking about being his rival... Didn't expect Veldora's rival to pretend to be my son..."

I awkwardly scratched the back of my head, "That's what he's been calling me over the past 300 years, but we actually fought once, and I was so drunk that time that I don't remember much."

"You fought Veldora while being drunk..."

"Hey, I was going through some stuff back then, got drunk, found a sleeping dragon, and like they say, the only way to wake up a sleeping dragon is to strike it where it doesn't have scales."

Rimuru's had a terrified expression and backed away from me.

"Hey, I don't normally act like that," I said, looking at him, "Oh, and just call me Cale. Not many have seen my true face or know my real name. So keep it a secret," I said, changing to my true appearance.

"Don't worry, I won't," He said.

"Oh, and another piece of advice, Rimuru," I looked at him seriously, "You shouldn't be so trusting in the future. Especially now that you established a magical treaty with the Armed Nation of Dwargon, this place will be seen as a nation and, coupled with its location and the fact that its citizens are monsters, could cause a serious problem."

"I'll keep that in mind," He said, and we sat in silence, drinking the green tea Shuna prepared for us, "Could you tell me why you became a Demon Lord?" He asked after a while.

"Hmm..." I hummed, remembering the day I first met Guy and became a Demon Lord, "It's probably the most boring reason out of all the Demon Lords," I chuckled, "I didn't have any other choice. I encountered a Demon Lord and wasn't that strong back then. Thankfully the Demon Lord was interested in my ability and strength and offered me to become one myself."
