It was just supposed to be another sunny day in the borders of the Golan Heights.

Spanning about 1,800 square kilometres (690 sq mi), the Golan Heights is a basaltic plateau bordered by the Yarmouk River in the south, the Sea of Galilee and Hula Valley in the west, the Anti-Lebanon with Mount Hermon in the north and Wadi Raqqad in the east; and as a geopolitical region, the Golan Heights is the area captured from Syria and occupied by Israel during the Six-Day War, territory which Israel effectively annexed in 1981. This region includes the western two-thirds of the geological Golan Heights and the Israeli-occupied part of Mount Hermon.

Which lead to an intergovernmental organization called the United Nations to call upon friendly nations to send troops to the troubled region which they are called the United Nations Disengagement Observer Force.

Often times, these UN peacekeepers needed to be accompanied by either the Israel Defense Forces or the Syrian Arab Army against Islamists hardliners.

Which lead to this—

"Such misfortune!"

The tranquil atmosphere of the cold dawn was shattered by a rocket-propelled grenade smashing through the first gate of the UN compound. Immediately, the familiar Type III camouflage of the Japan Ground Self Defense Force was donned by its members as their Type 89 assault rifles began to fire back.

"Off all times, this stupid thing jammed right now!"

The voice of the unlucky Kamijou Touma was heard—wait, what was he doing here?

"I'm just supposed to be a cook here, right?" Kamijou cried softly as he was forced to switch to his backup Minebea PM-9 submachine gun. "Why did I ended up here in the battlefields?!"

As he sprays 9mm rounds, he found himself wondering…

Why the hell did Japan ended up getting involved in this?!
