Red Comet: “Amuro Ray, what kind of ability is it to bully recruits, come out and face me if you have the ability!”

Lin Youde shook his head: “What you’re looking for is Amuro Lei, what does it have to do with me, Li Abao?”

Go offline and return to the real world, to Konaku.

Lin Youde looked at the steel giant in Gnaku and couldn’t help sighing.

“Gundam is so handsome~!”

Correspondent: “Dr. Lin Youde, I have your sortie order.”

Lin Youde sighed: “Have it started again, stupid soul bound by gravity.”

Entering the cockpit of the red steel giant and opening the open door, Lin Youde said seriously.

“You guys, are you going to start a war again?”

“I just want to play games in peace!”

“Lin Youde, Gu Tie, attack!”

- Description from novelbuddy

Sam Sanderson is envied by many for his job, however he himself didn't seem to like it much.

Due to his expertise in nanotechnology he was tasked with monitoring the state the Valkyries, humanity's strongest weapons who all just happen to be made into gorgeous females.

Forbidden from even touching any of them, Sam spends his days in agony watching flowers he couldn't hope to touch. However one day all of that seemed to change.

Rein Aster was just a herbalist farmer from a border village.A nobody. A background NPC in a story filled with prophecy and divine warfare.But by chance—or fate—he saves one of the 7 Demon Lords during a catastrophic war event. Instead of killing him, she falls for him.Obsessively. Violently. Eternally.And then… so do the others.Each Demon Lord tries to trap Rein as her personal lover/pet/priest/husband/god, building dungeons, illusion palaces, soul prisons—but Rein keeps escaping. Quietly. Cleverly. Never fully rejecting them—but never submitting, either.Why?Because Rein realizes something:The gods are worse than demons.The heroes are tyrants in shining armor.The world is collapsing—and he’s the only one they all listen to.So he hatches a plan:Use the Demon Lords’ love to take over the world.Pit them against the heroes. Unleash them on the gods. Make them fight for him. Make them kill for him. Then tame them all.Not as a king.Not as a savior.But as the lover they would burn the world for.__________The yanderes here are darker than what you might be used to.You have been warnedThe entire novel has a dark feel. Atleast read the first two minor arcs
