S1 E1 • Les forces d'Auto-Défense vers un monde parallèle

Itami Youji is a 33-year old otaku who enlisted in the Japan Self-Defence Forces to support his hobby. He is in Ginza to attend a doujin event when what becomes known as the Gate opens, and warriors and monsters enter and attack the people. His presence of mind and valour in the face of the unprecedented events helped save the lives of many civilians, and he is acclaimed as the Hero of Ginza, and even receives a personal citation from the Prime Minister himself, and is promoted to second lieutenant. The mysterious Gate remains open, and while no more creatures have come in from the other side, the Japanese Government remains deeply concerned, and they assemble an expeditionary force to explore the mysterious land beyond the Gate. Youji is of course chosen to be part of this force.

S1 E2 • Deux armées

The JSDF expeditionary force remains camped just outside the Gate on the other side, and decimates the allied forces that attack it, their medieval-level technology no match for modern weaponry and military tactics. This is, however, actually a gambit by Emperor Molt to weaken the kingdoms that are only nominally under his authority and keep them from rebelling. With their armies largely destroyed they are unable to resist his subsequent scorched-earth tactics. The emperor`s daughter, Pinya, is ordered to lead her order of knights to investigate the JSDF and learn all she can about them. Meanwhile, back on Earth, the President of the United States considers sending an American force beyond the Gate as well, lured by the prospect of immense resources in the lands beyond, despite the political implications. Domestic opposition in Japan to the JSDF`s operation beyond the Gate is mounting as well, so the President is convinced to bide his time. Youji is made commander of a reconnaissance unit whose job is to make contact with the locals and establish friendly relations with them. Along the way, they find a dragon burning a village. When they reach it after the dragon leaves, they find a woman at the bottom of a well, apparently the only survivor.

S1 E3 • Le dragon de feu

Youji goes down the well to pull up the woman, a blonde-haired elf maiden. The Third Reconnaissance Platoon then returns to the nearby village of Coda with the still-unconscious elfmaid and tell the mayor about the dragon, which terrifies them, and they make preparations to evacuate. Youji asks the mayor what happened to the lord who ostensibly ruled over their lands and why he wasn`t doing anything to help with the dragon, and was told that their lord never returned from the last battle near the Gate. While the Platoon helps guide the villagers away from the dragon a group of bandits thinks to attack them and in so doing become their new lord. A demigoddess named Rory Mercury slaughters them without mercy. The next morning she meets with the village and the Platoon, and seems to take a liking to Youji. Soon enough, the dragon attacks them, and kills a sizeable number of villagers. Even modern weapons are at first ineffective against the dragon, until the elfmaid and Rory help the platoon to injure it badly enough that it is driven off. After the villagers bury their dead, most of them are able to settle in other villages where they have kin. The young apprentice of an old magician, named Leilei, the elfmaid, Rory, and a few others remain with the Platoon.

S1 E4 • En terre inconnue

Youji has brought his platoon and the small group of refugees back to the JSDF base camp at Arnus Hill near the Gate. His decision to do this stirs up controversy in the upper ranks. The girl Leilei proves able to learn Japanese rather quickly and becomes interpreter. They are fascinated by modern technology but are concerned that they must find a way to repay all the help they are being given. They see a battlefield full of dead dragons killed by the JSDF during the last battle, and attempt to harvest the dragon scales and trade them at the nearby city of Italica. At the same time, Pinya travels throughout the lands and hears stories of the doings of the JSDF from some of the survivors of Coda Village. She finds one of the imperial vassal kings, badly maimed after the battle at Arnus Hill, who tells her of the slaughter and how he realises how they had been used by the Emperor. She resolves to visit Arnus Hill and see these invaders for herself. They also have to pass through Italica to get there. Meanwhile, back on Earth, the President of the People`s Republic of China makes plans to colonise the land beyond the Gate as well. Garbled reports of the incidents involving Youji`s unit serve to make a public relations nightmare for the Japanese government, and the exploration of the land beyond the Gate continues to lose popular support. The Diet of Japan summons Youji and his refugees, but by then they have already departed.

S1 E5 • La bataille d'Italica

Many of the soldiers who survived the battles at Arnus Hill against the JSDF have turned to banditry, and Pina finds herself in command of the defenders as Italica is besieged by these bandits. The city, after the sudden death of its lord recently is nominally ruled by the late lord`s daughter Myui, who being only eleven obviously cannot lead the defence, and so Pina and her Rose Knights offered to do so. During a lull in the fighting, Itami`s platoon, with Leilei, Rory, and Tuka arrive, and convince Pina that they are friendly and are willing to help defend the city. This is Pina`s first true battle: her Knights were relegated solely to a ceremonial role before, and she is not doing well. She had Itami`s platoon guard the south gates, as they are the most difficult to defend, but that night the bandits unexpectedly attack the east gate and overwhelm their defences. She thinks of calling Itami to help but fears he will not come after having put him in what looked like a suicidal position. It seems though that Itami will help of his own initiative.

S1 E6 • La chevauchée des déesses de la guerre

The fighting continues at Italica. The eastern gate`s defences are breached, and there is fighting in the city. Rory goes into a battle frenzy, with Itami`s troops behind her. Itami has also called in a squadron of helicopter gunships, and they terminate the bandits with extreme prejudice. This awesome display of modern military firepower leaves Pina in a state of shock, and she realises that a war with them would result in their inevitable defeat. She is equally shocked that Itami does not demand crippling terms which the victors in such a battle usually do, merely requesting trade concessions in exchange for the continued sovereignty of Italica. Leilei sells the dragon scales, and the 3rd Platoon tries to return to the JSDF basecamp at Arnus Hill, only to encounter Pina`s Rose Knights, who do not yet know that the battle is already over and that Pina has negotiated an armistice. They threaten Itami, who allows himself to be captured, ordering his troops to leave him behind, to avoid more fighting.

S1 E7 • La détermination de la princesse impériale

The Rose Knights treat Itami very roughly as they bring him back to Italica, so much so that he is knocked unconscious. Pinya is livid, as they have then violated the treaty so soon after it had been agreed upon and she fears that the JSDF will use the incident as a pretext to attack, so she orders Bozes Co Palesti to make it up to Itami with her body. In the meantime, Itami`s platoon sneaks into the city in an attempt to rescue him, to find that he is being well cared for by several semi-human maids and they have a small party. Bozes arrives and slaps Itami after she sees that he seems to be having fun. Pinya and Bozes join Itami`s group as they return to the camp at Arnus Hill, and along the way they see further evidence of the JSDF`s overwhelming military might as they conduct a training exercise. Pinya speaks to General Hazuma, the commanding general of the JSDF forces at Arnus Hill, apologising for the incident. The next day, she joins Leilei, Tuka, and Rory as part of the delegation from beyond the Gate for the audience with the Diet of Japan.

S1 E8 • Le Japon de l'autre côté de la porte

The five girls from the Special Region pass through the Gate with Itami`s unit, and are astounded by modern Tokyo. A Public Safety intelligence officer named Komakado meets them and escorts the group to the Diet. Pinya and Bozes are not part of the official delegation and attend a private meeting with cabinet officials in preparation for a possible future peace conference with the Empire. At the same time, Leilei, Tuka, and Rory are brought before the Diet into what becomes a sensational public hearing. Some members of the Diet opposed to the JSDF`s operations beyond the Gate try to paint Itami`s attempt to save the villagers from the dragon into a bad light, but the three girls are having none of it, and stress that the lieutenant did the best he could under such difficult circumstances, and in so doing humiliate their spokeswoman. Komakado is concerned about possible attempts on the Special Region girls, and so gets them to leave the Diet using the subway rather than the cars they were expected to use, which are promptly attacked. Whoever is attempting to capture them also seems to have control over the subways as certain lines they are about to use inexplicably fail. They are attacked by a man in the street who tries to take Rory`s axe, which is incredibly heavy, which incapacitates both the attacker and Komakado who both unwisely attempt to lift it. To hide them, Itami brings the girls to the house of a famished young woman whom he introduces as his ex-wife.

S1 E9 • Combat nocturne dans les reliefs de Hakone

Itami`s group spends the night at his ex-wife`s home, and decide what to do next. He has the girls go out for a bit while he meets with the Minister of Defence, who is an old friend, and he is ordered to bring their guests to the Hakone Mountain resort that had been prepared for them and is guarded by elite Japanese special forces. Itami brings them there as ordered, and after they are settled there is fighting just outside as several groups of enemy commandos make their way to the resort. The Japanese special forces unit manages to neutralise most of these mysterious enemy forces. However, President Dirrell blackmails the Prime Minister with reports of government corruption and convinces him to get the unit guarding the resort to withdraw, so that the American commando unit can abduct the girls from the Special Region with no interference. Rory Mercury is heavily affected by the fighting outside the resort and tries to seduce Itami.

S1 E10 • Espoir et désespoir

The American paramilitary officers approach the Hakone resort unchallenged, only to find that there are also Russian and Chinese paramilitaries there, apparently on the same mission. A bloodbath ensues when Rory joins the fray, and eventually all of the invaders are killed. Itami`s party escapes by commandeering the van used by the American paramilitaries, and they drive back to Tokyo. Itami`s ex-wife Risa spreads the word that the girls will be heading back through the Gate that afternoon, so a large crowd gathers at Ginza to see them off. Meanwhile, the Prime Minister has resigned, removing the blackmail leverage that the Americans had, but the Central Intelligence Agency is still attempting to abduct the girls, planning to take them just as they arrive at Ginza, since the assurances of the previous administration should still hold. However, Komakado has arrested all the foreign intelligence agents in the area, including the CIA ones, saying that he has no way of verifying whether any such agent he finds is with the CIA or not, foiling their plans. Itami`s party thus returns to the Special Region unmolested.

S1 E11 • Un visiteur

Itami`s squad and the girls have returned from Japan. The JSDF basecamp at Arnus Hill has become the centre of a thriving town as trade across the gate between the Special Region and Japan flourishes. Pinya and a Japanese diplomat have begun meeting with imperial nobles, attempting to convince the most hawkish of them to consider peace with Japan by giving them gifts and negotiating the release of important prisoners of war captured during the first assault by the Empire against Japan. Meanwhile, Itami is at a tavern with Rory, who is still trying to seduce him. A dark elf woman named Yao Ha Dyusshi appears, looking for what she calls the "green men" (the JSDF) trying to get their help. She denounces Itami for apparently corrupting a minor, and her interference irritates Rory. She makes the misunderstanding deep enough that the Yao draws her sword on Itami, who flees. It turns out that Yao is looking for help to finally finish off the fire dragon that Itami`s group encountered earlier, and offers a huge diamond as reward.

S1 E12 • Si c'était Itami...

Yao goes around the settlement of Arnus and the JSDF basecamp, but is unfortunately unable to make herself understood to the JSDF soldiers she meets. She falls prey to thugs and robbers but is able to defend herself but one of them reports her and she is eventually arrested by MPs. Leilei, being the best bilingual speaker manages to get her story and the thug is instead taken into custody, and she eventually secures for Yao an audience with General Hazama. Yao explains her errand, but the General refuses to help. The settlements of Yao`s people can only be reached by crossing imperial territory, and if he sends enough forces there to defeat the dragon that would be interpreted by the Empire as an act of war. Frustrated in her mission, she overhears stories about Itami and how he might manage to do something to help, and so when she goes to the refugee dormitories she asks Tuka about him. Itami meanwhile has escorted a second diplomat to join Pinya, and is being sent as part of a delegation to the capital.
