"Protect the Empire" was considered unbeatable for over a decade until streamer extraordinaire "Mr. Gamer Geek" comes along and defeats the game on its hardest mode. But just when he's about to rest on his laurels, he's sucked into the world of the game by some mysterious figure and thrust into Prince Ash's body! Ash now realizes that every click and command he had mindlessly sent out had real, gruesome costs—including his teammates' lives that he sacrificed for the sake of victory. To make up for his previous actions, Ash promises to keep his whole team alive this time while using his wits and knowledge to survive the hellish onslaught of monsters. But who brought him to this world in the first place, and why? Ash may soon find the answers to these questions—if he can survive the bloody battlefield first!

A modern man is reincarnated into the world of a fantasy game he knows well: as Werner, the son of a powerful noble. The thing is, Werner isn't the hero or even the villain—he's a background character likely to die during a climactic siege! Werner seeks out and befriends the hero, but he doesn't have powerful enough skills to be a hero himself. Unwilling to die as a later plot point, Werner uses his knowledge of the game and his power as a noble to aid the hero and defend against evil attacks. That's when he realizes that when he does so, he saves other people who were doomed as he was, which changes the "plot" he thought was inevitable. As the hero's close comrade who can see the future, perhaps Werner will be a savior to this place, after all!

Isayama, Hajime

Hundreds of years ago, horrifying creatures which resembled humans appeared. These mindless, towering giants, called Titans, proved to be an existential threat, as they preyed on whatever humans they could find in order to satisfy a seemingly unending appetite. Unable to effectively combat the Titans, mankind was forced to barricade themselves within large walls surrounding what may very well be humanity's last safe haven in the world.

In the present day, life within the walls has finally found peace, since the residents have not dealt with Titans for many years. Eren Yeager, Mikasa Ackerman, and Armin Arlert are three young children who dream of experiencing all that the world has to offer, having grown up hearing stories of the wonders beyond the walls. But when the state of tranquility is suddenly shattered by the attack of a massive 60-meter Titan, they quickly learn just how cruel the world can be. On that day, Eren makes a promise to himself that he will do whatever it takes to eradicate every single Titan off the face of the Earth, with the hope that one day, humanity will once again be able to live outside the walls without fear.

Tanya Degurechaff is a soldier who has the appearance of an innocent young girl. But behind her cute facade lies the soul of a ruthless salaryman who challenged "Being X"—the self-proclaimed God who reincarnated the man into an industrial world of magic. By doing this, Being X hopes to prove that, if the situation were dire enough, even a non-believer like this man would pray for God's help.

Opposing Being X's desires to make her suffer, Tanya enlists in the military with the hope of living a peaceful life. She manages to impress the higher-ups with her aptitude for war, swiftly rising through the ranks. However, her country soon participates in the ongoing world war, quickly crushing her dream. In an attempt to return to her calm she starts using any merciless means to obliterate her opponents. Thus begins the saga of Tanya the Evil and the Empire as they seek world domination.

1-Star heroes are just fodder for learning a boss' attack patterns. That was Seojin Han's philosophy when playing the notoriously difficult game Pick Me Up. But after being transported into the game as one of those 1-star heroes, he's got no choice but to rise in rank and defeat the player controlling him and his party. Can a gacha game character hope to defeat a player akin to being his god?

Pick Me Up

픽 미 업!

Toujou, Chika

Intrigued by the severe lack of faith a particular salaryman displayed as he drew his last breath, a godlike presence known only as "Being X" reincarnates him into a magical yet war-torn world to test his mettle. Under these new circumstances, Being X believes that, should this man succumb to relentless suffering, he will call upon the heavens for assistance.

Starting life again as a young girl named Tanya Degurechaff, the salaryman quickly utilizes his past experiences and volunteers for the military of his country, the Empire. Wielding tremendous potential despite being a child, Tanya's prodigious capacity for strategic and magical warfare allows her to quickly ascend the ranks and consistently lead her nation to miraculous victories in the ongoing war. Even so, she does all of this for one purpose: to live in the backlines far from the war zone, effectively defying Being X's objectives.

However, as Tanya strives to escape Being X's influence, she soon comes to know that even with her genius, there are situations that a human simply cannot overcome without divine intervention.
