Hirano, Kouta

At the start of the Edo period, samurai Toyohisa Shimazu is in the midst of a bloody battle against the legendary Tokugawa clan to ensure the successful retreat of the Shimazu clan forces.

After his entire unit is massacred, Toyohisa manages to single-handedly force the enemy to withdraw—at the cost of being mortally wounded. Walking out of the battlefield dejected, he mysteriously finds himself in a white hallway, where he is immediately thrown into a door. He awakens in a different world, and there, he encounters Drifters, other legendary warriors who died and ended up in the same realm. Together, they use the knowledge and experience from their past lives in order to take over an empire and fight against an unknown force of evil that intends to crush all humanity.

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.

The Saga of Tanya the Evil

幼女戦記

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.

One day in the 21st century, a gate opened in the middle of the Ginza district of Tokyo. Out of the gate poured soldiers and strange creatures, and they soon made Ginza look like an image of hell. The gate apparently connected Japan to another world, a world with a militant empire and many supernatural creatures. The Japanese Self-Defense Force decided to send a small group, led by a soldier who's also an otaku, into the other world on a reconnaissance mission. They're meant to learn what they can about the empire (and its plans), the world, and the people.

They're hardly in the world yet, though, when they come across a village destroyed by a giant fire-breathing dragon. The only survivor is an unconscious elven girl they find hidden in a well. Now they feel like they must warn the nearby towns about the dragon, and do what they can to help. On the way, they'll meet more magical, female companions, and learn more about this dangerous new world.

Gate: Where the JSDF Fought

ゲート 自衛隊彼の地にて、斯く戦えり

In August of 20xx, a portal to a parallel world, known as the "Gate," suddenly appeared in Ginza, Tokyo. Monsters and troops poured out of the portal, turning the shopping district into a bloody inferno.

The Japan Ground-Self Defence Force immediately took action and pushed the fantasy creatures back to the "Gate." To facilitate negotiations and prepare for future fights, the JGSDF dispatched the Third Reconnaissance Team to the "Special Region" at the other side of the Gate.

Youji Itami, a JSDF officer as well as a 33-year-old otaku, was appointed as the leader of the Team. Amid attacks from enemy troops the team visited a variety of places and learnt a lot about the local culture and geography.

Thanks to their efforts in humanitarian relief, although with some difficulties they were gradually able to reach out to the locals. They even had a cute elf, a sorceress and a demigoddess in their circle of new friends. On the other hand, the major powers outside the Gate such as the United States,China and Russia were extremely interested in the abundant resources available in the Special Region. They began to exert diplomatic pressure over Japan.

A suddenly appearing portal to an unknown world—to the major powers it may be no more than a mere asset for toppling the international order. But to our protagonists it is an invaluable opportunity to broaden knowledge, friendship, and ultimately their perspective towards the world.
