MTL - Inside and Outside World - Chapter 135 :Double insurance

What are you going to do when you pass through another world?

Yalin(MC): Perhaps, many of those seniors who passed through another world would like to use violence to solve their problems, but I like to control the fate of a country with economics and races with faith, I use benefits to instigate others so that I profit, and even making them take risk for me without them even knowing. In each country the highest is the king and behind the king is a string that is attach to my hand, for I am their puppeteer.

Yalin(MC): Certainly the credit does not only belong to me, I must give my thanks to the great knights and their leader Zero(Code Geass). The supreme master of blood, the moon princess(Tsukihime), the black and white princess, and also my ‘good friend’ called by his title the ‘God’s left eye’, president of the neutral autonomous city. Finally I must give thanks to my loyal and competent subordinates!

- Description from Novelupdates

[R18 novel with a lot of sexual content]Artem never expected to take on the role of a villain, let alone transmigrate between harem novels. Bound by a system, his task is clear: steal the heroines from all the protagonists’. From Chinese Cultivation and Korean Gate to Japanese Isekai Fantasy, VRMMORPG, and beyond—no heroine is off-limits, and no protagonist is safe!

Crimson Vale Academy—where reputation is currency, and failure is a stain you wear on your sleeve.Behind gothic walls and spotless uniforms, students aren't just educated—they're measured, ranked, and pitted against each other in a brutal meritocracy. Privileges are earned, not given. The strong rise. The weak vanish.Enter Kairon Vale, a transfer student marked Rank D—the bottom of the bottom. No badge. Just a stitched black fang, branding him as “Obsidian”—a warning to others.In a system where points dictate your value, Obsidian-ranked students claw for every opportunity to ascend into the prestigious Golden or Platinum ranks—where comfort, power, and influence await. But for most, it’s a losing battle.Yet Kairon isn’t here to fit in, impress, or play by their rules. Cold, calculating, and impossible to read, he watches the system… and waits. Because while the academy judges worth by numbers and names—he understands something deeper:Everyone wears a mask. And every mask can be cracked.Let the games begin.

[MATURE CONTENT]Arella is an angel.Well, she used to be an angel. A real, bona fide, halo-wearing, wing-flapping celestial being. That was until one tiny whoopsie where she unfortunately burns a pair of wings at a banquet happens.Fine!There was more than one tiny whoopsie.Fast forward a few hours later, and Arella found herself booted from the pearly gates with nothing but her wings and an eviction notice.Her family called it a “vacation.” Ha! A vacation, in the human realm of all places!One hundred years later, Arella calls it her new life. Turns out, living among humans isn’t half bad—especially when you can turn invisibly smug at their lack of ability to fly. Early retirement has never been so blissful. That is, until the heavens smack her face with a message: Arella’s back on duty. And her new job? Marry. The. Demon. King.Wait, what?!Marrying the Demon King isn’t exactly on Arella’s bucket list, especially when demons and angels have been sworn enemies for eons. But orders are orders. So, off she goes, wings drooping and attitude cranked to full sass, to meet her new husband—a devilishly handsome demon who seems unnervingly smitten with her.Not to mention the heat that surges within her the moment she lays her eyes on him. Cue in dinner dates, fiery arguments (literally), and a series of catastrophes involving Arella purposefully setting a demon's hair ablaze with her holy fire.But as Arella settles into this bizarre celestial-demonic union, she uncovers a sinister plot that threatens not just her marriage but their entire reality. Turns out, angels and demons might have to join forces to stop a threat that neither side can handle alone. And Arella? She might just be the unexpected key to saving everyone.Armed with nothing but her quick wit, trusty angelic powers, and a painfully doting husband who may or may not leave her love notes carved into rock when she is angry, Arella must navigate battles, betrayals, and the occasional marital spat to protect their world. After all, nothing says “happily ever after” like saving existence itself, .... right?Right?One fallen angel. One absolutely smitten demon king. And a whole lot of chaos.
