Moto Sekai Ichi'i no Sub-chara Ikusei Nikki - Chapter 21: The real deal

The brash Li Chengfeng makes a living through trickery with his clueless but loyal servant, Xiaobao. One day, the love of his life is murdered, making him a suspect, and he meets a demon who suspects he is the reincarnation of a traitorous immortal.

The Main Character, Watari Karito, is a veteran player of a Military Shooting VRMMORPG.

Imagine being forced to live, after death, as incorporeal bodies trapped in a vast space of nothingness for thousands of years, with nothing to do but exchanging past memories with other cohabitants (read: weirdos). Everybody wanted out, but there was no way to leave the Void…

Until one day, a young man was finally summoned, as a powerful but reluctant mentor, by a bubbly and motivated but completely naive young girl. Baiyi, finally out of the Void, was the only one who could save all of the other 32 souls from their prison and his summoner might just be The Key to their freedom.

However, Baiyi had to use the techniques and abilities the other souls had taught him throughout the years, and together with his own extensive knowledge of anime and game tropes from his shady and dangerous past as an otaku, to face the biggest challenge of them all: training the clumsy young girl he was forced to partner up with… into a competent sorcerer!

This is a story of heroic adventures, cunning strategies and romantic tales. How will our MC thrive in a world completely strange to him? Where will his ambitions and abilities take him in the palace?

- Description from Novelupdates

After her rebirth, Rita vows not to repeat her past mistakes. This time, her first priority is to stop her brother, who is about to marry into the Lopez family, from participating in the initial game beta test. In her previous life, she was deceived by this scheming brother until her dying breath. It was only at the end that she realized she was merely a villain in a male-oriented novel about a live-in son-in-law, with all the malice and manipulation orchestrated by him behind the scenes. In this life, Rita decides to change the rules of the game. She will stay in the shadows and seize all the opportunities meant for the male and female leads. By participating in the beta test and re-selecting her abilities, she systematically dismantles the protagonists’ advantages, all while making them believe she’s on their side. Rita has no intention of harming innocent people, nor is she a selfless saint. In this game, she works with the authorities for mutual benefit, all to achieve her ultimate goal—becoming the true master of her fate.
