MTL - I! The Villain Licks the Dog’s Father, Specializing In All Kinds of Protagonists - Chapter 6 I don't take rubbish!

A striking man of mysterious origin and peerless talent, he looks back at the world, in all its entirety, with utter disdain. And yet, in the treacherous and unpredictable ultimate formation of the Boundless Secular World, he guards a breathtaking ancient qin with broken strings, waiting silently for the destined one to arrive!

A boy encounters him, and knows for the first time that the world beneath the Heavens is a fickle place. Not even demons, devils, ghosts and monsters can match the frivolity of human nature!

A slender physique, and jade-like beauty, but the sword that strikes between heaven and earth is not unlike a streaming rainbow!

The vastness of the starry sky, the seven emotions and six desires! Greed, anger and ignorance! The teachings of Buddha will grant you boundless strength!

A sea of blood will come, at the cost of all mortal beings full of honest hope!

The ghosts wail as the gods roar, but the sea of blood has no end!

Where, pray tell, is the path I should take?

Since there is no path, no matter how bitter and bloody the sea, even if my boat is made out of bones, I will soar to the heavens above!

- Description from Novelupdates

A normal guy gets hit by a truck and isekai'd. Why? Because trucks are apparently some cosmic loophole. He decides to be a dungeon, because it sounds weird and interesting to be one. Is it? Let's find out.

Utsuro no Hako to Zero no Maria, or The Empty Box and The Zeroth Maria, tells the sinister story of Kazuki Hoshino, who is almost madly attached to his everyday life, and his antagonist Aya Otonashi, who suddenly transfers into his class—for the 13,118th time. She majestically announces to “break” him, without paying heed to anyone else around them.

Before her rebirth, she was abandoned by her parents, then murdered by her seemingly pure but vile younger sister. After her rebirth, she kicked all her scum boyfriends to the curb and began a campaign of abuse against the superficially perfect. Rumors were rife on the internet that Qin Sheng was a kept woman? A bunch of computer nerds, "Let's hack the keyboard warriors' computers." The first director, "Boss, have you written the script yet?" The medical expert, "Sheng Sheng, our research institute will give you 100 million. When will you be able to join our team?" A famous painter, "Sister Sheng, take me along when you hold your art exhibition." The CEO of a billion-dollar company, "Boss, when are you going to publicly disclose your identity?" Finally, a big boss pulled Qin Sheng into his arms. "Sheng Sheng, I've transferred all the assets under my name to you." Netizens, "?? This world has suddenly become crazy?" She was a business genius, a computer genius, a legendary screenwriter, a legendary painter, and a legendary medical expert. It remained to be seen how she would create flourishing prosperity. (The male protagonist has a propensity for recognizing bitches, but is infinitely sweet and doting to the female protagonist!)
