Touya is dead due to God inadvertently dropping some lightning on him by mistake. He then would be resurrected in a new world. He met new friends and became adventurer. He also learned magic and surprisingly he master all element.
After defeating Mithril Giants Touya and Yumina are promoted. Leen wishes to search for the Babylon teleportation array so they can find the other floating islands. Touya is uncertain but promises to help if Leen first locates the array by herself. God summons Touya to check on him and Goddess of love insists that, since he has already given engagement rings to his four fiancés, he needs to step up the romance. The fiancés worry people may take advantage of Touya’s kindness in the future. Touya takes Yae to replace her broken sword with a mithril one and agrees when Yae asks to hold hands. The king is thrilled by Yumina’s engagement but the queen worries it will expose Touya to jealous rivals and advises Touya to increase his achievements. Touya realizes marrying Yumina might make him king one day. Touya helps his friends attract more customers to their inn by building them a hot spring bath. In the bath the fiancés share their reasons for falling in love with Touya. Francesca attempts to join Touya in the bath but triggers a paralysis spell Touya installed to prevent spying. Leen announces she has already found the next Babylon island.
Everyone travels to Sandora Kingdom in the desert and spot another glass beast, now known as a Phrase, chasing a group of people. Touya encounters Ende again who defeats the Phrase. Ende reveals the barrier protecting the world against the Phrase is weakening, allowing the Phrase to search for their King. Ende teleports away. The group are adventurers led by Rebecca escorting runaway slaves to safety, so Yumina offers them sanctuary in Belfast. Touya reveals Ende was a foreigner he helped join the adventurers guild. Francesca reveals Regina created a robot suit as an anti-Phrase weapon, stored on a Babylon island in a vehicle hanger. Excavating the Ruin, Touya is teleported to Babylon’s Workshop and meets Rosetta, who offers him the workshop if he guesses the colour of her underwear. Exasperated, Touya uses magic to see under her dress and finds her panties are completely see through. Rosetta kisses him, registering his DNA, and shows him the workshop is an ultimate tool that can create any item, so Touya creates an upgraded pistol-sword from mithril. Touya sends the Workshop island to Belfast to merge with the Garden island. At Rebecca’s request Touya takes in the slaves until they can find employment.
Touya creates jobs for the slaves by opening the Moon-Reader library/café and employing them. Will, one of Rebecca’s younger adventurers, tells Touya of another Null spell, Gravity. Guild secretary Prim requests he stock a particular book series at Moon-Reader. Yumina frets as the series is a Yaoi erotic series anonymously written by her close friend Reliel, Princess of the Refreese Imperium. Deciding it would be good for business Touya agrees but is inundated with requests for similar books from his female customers. Visiting Refreese for the books he encounters a strange Yaoi obsessed girl who, desiring one of the books he already bought, offers to trade her autograph, accidentally revealing she is Reliel incognito. Touya copies the book for her using the Workshop while she reconnects with Yumina. Will has a crush on one of the former slave girls and wishes to be able to protect her, so Touya sends him to train with the royal knights. While visiting Silver Moon with Elze Touya collects a cute outfit he designed for her which she loves. Reliel writes a new book about a bisexual magician blatantly based on Touya, who promises much punishment if he ever sees Reliel again.
Touya visits the Regulus Empire for more books and finds civil war has broken out as General Bazoar rebels against Emperor Zephyrus. Touya rescues Princess Lucia and her bodyguard Carol. Bazoar intends to invade Belfast, Mismede and Refreese with two Artifacts that let him summon a demon resistant to magical and physical damage. Touya teleports away with Zephyrus, Lucia and Carol but cannot find Lucia’s brother Prince Romero. Yumina, sensing Lucia has a crush on Touya, invites her to a private conversation. Yumina’s father announces the Queen is pregnant and if it is a boy it would inherit the throne instead of Touya, which the King had intended by marrying Touya to Yumina. Rosetta reveals the two artifacts should have been on the Storehouse island. Using his phones search function Touya locates Romero. Touya defeats the demons physical resistance by hitting it on the head with his sword, enchanted by Gravity to weigh hundreds of tons. He then defeats Bazoar’s magic resistance by exposing him to a Sludge-slime emitting such a foul stench Bazoar faints. Zephyrus reclaims his throne but Touya is unable to celebrate with his fiancés who are repulsed by the stench stuck to his clothes.
Against Touya’s usual objections his fiancés, Tristwin and Zephyrus reward him by engaging him to Lucia to ensure peace between Belfast and Regulus. They also grant Touya lands at the border of both kingdoms to rule his own (very small) Kingdom of Brunhild, free from interference by other kingdoms. Using Workshop and raw materials from a derelict castle, Rosetta builds a castle in Brunhild to Touya and the fiancés specifications in a mere three days. Leen deliberately gets a job as Mismede’s ambassador and moves into the castle too. Emperor Rig of Refreese Imperium is the first to begin diplomatic relations with Brunhild and Touya narrowly avoids engagement to Reliel who fortunately is already engaged. While preparing to host the grand opening of the castle Touya is visited by Tsubaki who reveals the Takeda clan has collapsed due to the new Lord’s corruption, so she and her entire clan wish to serve Touya as Brunhild’s first citizens. With help from Kousaka Touya begins constructing a city and a merchant’s network. The party is a success with kings from every nation in attendance. During the fireworks display Touya provides Lucia her own engagement ring before holding hands watching the fireworks.
Touya and the girls locate another teleportation circle that sends Touya to the Alchemy Laboratory Island with its keeper Flora. Flora accepts Touya after making him grope her breasts. Touya learns the lab is an advanced medical facility Professor Regina used to create sexual stimulants. Touya locates a Null spell that lets him fly. Love Goddess informs Touya it is time to meet Yae, Elze and Linze’s parents. Yae’s father demands a duel with Touya, but when Yae offers to duel her father instead he accepts their marriage. Elze and Linze’s aunt and uncle accept their marriage without issue. Ende appears and reveals the Phrase are searching for their King’s power core which is somewhere inside a random human. Ende is also looking for the core and claims he is just a Traveler on a 5000 year adventure. Touya asks Francesca to mass produce the anti-Phrase suits, but the Workshop doesn’t have the materials. Needing materials and the other islands quickly Kohaku suggests contracting the Flame Emperor, a Phoenix and Queen of Birds. Upon summoning her she easily agrees to a contract and is named Kougyoku. With her power over birds Kougyoku sends every bird in the world to search for the still missing teleportation circles.
The birds locate another teleportation circle. Reaching the island Touya meets Fredmonica who registers Touya as owner of her Hangar Island and the anti-Phrase Frame-Gear suits. Unfortunately, the suits run on Ether Liquid which can only be made by the still missing Research Lab island. Flora offers to make an inferior version, but requires a rare spellstone over twelve inches long, of which there are only six in the entire world. Fortunately, one is in Brunhild, so Flora promises to have the fuel ready in one month. Touya and the fiancés train in Frame-Units, virtual reality machines that simulate piloting a Frame-Gear. Sue abruptly demands to be Touya’s next fiancé as she is being pressured to marry Prince Zabune of Linhea Kingdom, a 30 year old man suspected of paedophilia. The fiancés consent to Sue marrying Touya for her protection. Touya learns Zabune’s maternal uncle Wardack is Linhea’s Prime Minister and frequently conceals Zabune’s crimes. Zabune also has a much kinder half brother, son of the king’s concubine. Sue’s father Duke Ortlinde informs Linhea’s diplomatic emissary Sue will be marrying Touya. Hearing this the emissary reveals he is Cloud, Zabune’s brother, and begs Touya to use teleportation magic to rescue his imprisoned mother.
Cloud reveals Wardack is the true power in Linhea, even controlling the King, and imprisoned Cloud’s mother to ensure Zabune inherits the throne. Duke Ortlinde summons the leaders of all western kingdoms to discuss removing Wardack and Zabune from power and instating Cloud in their place, though in the end they leave everything to the exasperated Touya. Touya infiltrates Linhea and confirms Zabune is a scumbag who keeps female slaves and Wardack plans to start a war with Palouf kingdom to have Cloud killed. Touya quickly rescues Cloud’s mother Erya and teleports her to safety, along with Koupe, Linhea’s former Prime Minister whom Cloud trusts. Touya then records Wardack confessing that he is actually Zabune’s real father, having seduced Zabune’s’s evil mother Queen Dacia, and plans to assassinate Cloud and the King to replace them as the new royal family. Touya reveals everything to Linhea’s king who immediately declares Cloud his sole heir and retires to be with Erya. As king Cloud has Wardack, Dacia and Zabune sentenced to death then secretly sold to a foreign slave trader. Koupe is reinstated as Prime Minister and banishes all nobles who supported Wardack. Cloud joins Touya on the Alliance of Western Nations. Sue is happy she gets to marry Touya.
Touya attends the wedding of Olga and Lyon, causing him to realize he will soon have to attend his own six weddings. Yumina demands Touya take everyone on dates since he is often busy and neglects them for long periods. Touya takes them shopping and to the theatre, with a short stop to arrest some bandits. Returning home they realise they forgot to include Sue who demands her own date alone with Touya. He takes her on a tour of Brunhild where his citizens are happily settling in. Flora completes the Ether Liquid allowing the Frame Gears to activate. At Touya’s suggestion Flora uses crystal from dead Phrases to make weapons that, like the Phrase themselves, grow stronger the more magic is put into them. Flora requests Orichalcum to build more Frames, so Touya hunts for an Orichalcum Golem, though as he flies over Lestia Kingdom he sees it under attack by numerous Phrases. After destroying them with his crystal sword he meets Lestia’s knight princess Hildegard and impulsively gives her several crystal swords to promote diplomatic relations. After finally hunting his golem Touya discovers a girl in the woods missing a hand and a leg from a vicious attack.
Flora restores the missing limbs of the girl Touya found with the Alchemy Lab, but reports she has amnesia. Touya temporarily names her Sakura for her pink hair. Sakura turns out to be an excellent singer, so Touya shows her the piano, hoping music will jog her memory, but Sakura remains amnesiac. The guild sends Touya after a Catoblepas, a monster that can turn people to stone. Thirteen adventurers have already turned to stone, so Touya accepts, hoping Null healing can save the adventurers. His fiancées, except Leen and Sue, insist on joining him, so he replaces their normal weaponry with Phrase crystal replacements. The Catoblepas is defeated without casualties, except for Lucia, who is stoned up to her waist. She recovers through Null healing, but when the stone crumbles, it shreds her clothes, leaving her without panties. A second Catoblepas appears, though luckily it is killed without Touya seeing Lucia exposed. Unfortunately, when Touya naively heals the thirteen adventurers’ too quickly, he ends up with thirteen men and women totally naked. Touya gives a Frame Gear to every kingdom as a gift. In Lestia, Hildegard hopes to see Touya again. Her grandfather Galen, reputed to have been as strong as Touya in his youth, becomes interested in Touya as well as his advanced technology.
Touya oversees construction of his personal Frame Gear, Night-Baron. Love Goddess appears in person, claiming to be Touya’s sister Karen, so she can have fun observing his relationships in person. Not quite coincidentally, Hildegard visits with Galen. Galen is impressed with the crystal swords that Touya gave them earlier along with his intentions to share the Frame Gears between kingdoms, so he decides to convince his son, Lestia’s current king, to join the Alliance of Western Nations. After having a friendly duel with Yae, Hildegard is clearly disappointed Touya has six fiancées already, but after some meddling by Love Goddess, asks to become his seventh fiancé. Galen is unconvinced and demands a duel, though not with Touya but with Hildegard, to prove her resolve. Hildegard is accepted onto the Council of Brides but worries she may not defeat Galen, though the fiancé’s are certain Touya has a plan. Touya does indeed, knowing Galen is a lecher, he distracts him during the duel with a holographic projection of a bikini clad woman. Hildegard wins, but the fiancées demand to know why Touya has bikini pictures. Hildegard is curious about Touya’s parents who no one has met (unaware that he isn’t from this world), though Love Goddess assures them Touya will tell them when he is ready. She then thrills the fiancé’s with Touya’s embarrassing childhood stories and prevents Kohaku from alerting Touya.
Kougyouko locates the Rampart and Tower Islands and their keepers Preliora and Pamela. The Tower is the center of the islands and functions as a magic generator, while the Rampart can generate a magical shield. Preliora hints Professor Babylon foresaw Touya’s future. Queen Yuel gives birth to a boy, replacing Touya as Belfast’s future king. Touya names the boy Yamato. The baby makes the fiancés realize they will likely have children in a few years. The keepers confirm the Professor foresaw Touya’s nine wives having at least one child each, corresponding with there being nine Babylon islands. Touya is baffled that he hasn’t even met his next two wives yet. He unsuccessfully tries to conceal the information from his fiancés and they decide to punish him for trying to hide it like an extramarital affair and sentence him to kiss each of them, much to his anguish. At a party to celebrate Yamato’s birth, the group watch from the castle balcony. Yumina impulsively kisses Touya early, causing Linze to kiss him too and Touya just kisses Sue on the cheek. Lucia runs away embarrassed and Hildegard faints. Yae kisses him but panics and beats him up. Elze kisses him as well and also beats him up. Afterwards, Elze helps Touya up and the wives all smile at Touya and they continue watching the fireworks. The keepers locate the Professor's future sensing Clairvoyance Gem and discover the other two wives will be Leen and Sakura.
