DxD: Scion of Lucifuge - Chapter 300: The War Game Begins—Yukari’s Light Magic—Megumin, the Melee Mage

Kazuki’s life was painfully average—just another cog in the nine-to-five grind. His only escape? Binge-reading novels and no-lifing video games.Then he woke up inside one of those novels.Armed with unstable morals, unhinged humor, and a penchant for pettiness, Kazuki is determined to survive, thrive, and maybe cause a little chaos along the way.The world has no idea what’s coming.

Before the disfigurement, everyone loved Ling Chunan. After the disfigurement, Ling Chunan became a plague that everyone avoided. He was held on captive by his own agent afterwards because he was so ugly now, desecrating his love. Finally, Ling Chunan chewed himself to death because he was starving. After his death, a thing that claimed to be the counterattack system 098 found him.

A long time after, a certain counterattack system of a host with a 100% success rate posted a message in the System Forums.

《Emergency Help Request, my host is a masochist! He won’t be happy if every meals doesn’t have meat, and if he doesn’t have meat to eat, he will start to gnaw himself! How to treat this illness?!》

Great God : No need. I have a fast recovering ability. I will let him bite me.

You Liangxing would never open the speech function in game.
That was because his voice was…
Particularly! Kittenish!

But there was one day, he queued up with a teammate who had so much to say that they may as well explode. Vexed to the point of no return, he contributed a voice that was capable of splitting heaven and earth, “Don’t BB.”
The other party who was being scolded stilled. In the ensuing silence, he suddenly let out a long, relishing… Moan.
You Liangxing: “…..”

Later —
