It's pretty much explained everything in the title so...

Ehn-na? Ehn-ne-ne Ehn-ne? EHN-NE-NA?!

A science-fantasy crossover, that asks "what if the world of Arknights met the 21st Century United States." Beneath the classified depths of Area 51, a decades-long black project known as Project ARKSEK has achieved what was once thought impossible: the creation of a stable, functional gateway to another world. In the wake of this discovery, the United States mobilizes its most advanced and sophisticated military units and scientific minds to establish the first Human presence beyond the Gate. However, this new world known as "Terra" by its inhabitants is no empty frontier. It is a world shaped by its own complex histories, societies, nations, geopolitics, and scarred by Catastrophes. Home to diverse nations built upon the foundation of Originium, an enigmatic energy rich mineral that fuel its entire civilizations but also spreads a deadly disease that has no cure, known as Oripathy. What begins as an exploration mission slowly becomes something far more what the US could have ever bargained for in another world. Fraught with discoveries and dangers unlike anything humanity has ever encountered before. As American forces attempt to understand and navigate this alien yet familiar landscape, they will be forced to confront questions of morality, control, diplomacy and weighing the cost of intervention. What they will find on the other side may change the future of both worlds. For better or for worse. Every discovery always has a cost. And some doors, once opened, cannot be closed.

When I opened my eyes, I was reincarnated in the Blue Archive universe 'Kivotos'? But why Abydos?!? The story of Bina who became a student of Abydos A remake of Midududoo's fanfic 'I Became Bina Talking to Myself' Author: I want to Dreams

We pose you a question, dear viewer from the outside. In the harshest of environments, the most barren of them all... Will a single small, blue flower like this one grow and bloom in the golden sands of abandon? Or will it wilt and die like the white flower before it? Huhu... let's find out, shall we? And one more thing before we leave. Can the small, blue flower still dream her everlasting, beautiful, blue and white dream? As always, the narrative continues in the distant realm called Archive of Our Own as well, but this is where we say goodbye for now.

A young girl in Kivotos was preparing for the entrance exam, but it looks like the soul of a 33 years old who wished for a quiet life influenced her to the point that a hand felt like a food.

An unfortunate soul wakes up in a disjointed body. Amidst one of Ruan Mei's experiment, a Herta puppet, which she had 'borrowed' earlier laid down on a table. The anomaly who regained life, a puppet with individual mind, completely separated from the hive. This is a story, of one who regains his humanity albeit in a different constitution... "Octa, I have found your lack of progress unamusing. Which is why I'm handing you over to the express." "Logic circuit error. Unable to comprehend order-" "I will not take any complain from you. Go." "Understood..." ...

TL;DR - The protagonist becomes G36

One would expect a new chance in life would be exciting? Not so much when your a mental hazard to everyone and the worse part? The world ain't safe against him.
