While Blaine and his friends were sitting on the flying steam bus that already left Sakurahama Island, they started to notice the sun getting covered by dark clouds accompanied with a thunderstorm and Emil said "I don't think we'll get into our destined location..." Mayra replied "Yeah... We don't think so..."
Suddenly, Ostara saw an airship opposite the bus and told Blaine, Silvia, Mayra and Emil to avoid the ship, only for the airship to shoot a bullet into the bus's steam engine, causing the four (except for Mayra who can activate her own wings) to gain angel wings and the bus to crash near Featheria Island.
In Featheria Island, the five managed to land successfully, only for the airship to capture them a moment after the bus crash. 2 hours later, the first people to witness the crash were two kids, around the same age as Icicle, and they are Mathias and Delilah. The two saw the destroyed bus and climbed to the top of the bus, aiming their weapons in the air in front of the journalist who first witnessed the scene before them taking a photo of them in that pose.
5 hours later, the mayor of the affected village, and told the journalist, Mathias and Delilah to stay away from the bus crash site and stand with the villagers in front of him, before telling to the villagers the rainbow bridge that connects Featheria Island to Sakurahama Island got broken by the bus that crashed 7 hours ago and the only way to repair the bridge is to mine rubellite in northwestern Featheria Island, and it was complicated for the villagers to walk across the northwest of the island.
Mathias and Delilah told the mayor "Can we mine some rubellite to repair the bridge?" He said "Sure thing, but you'll need someone else to help you out. Would you mind that I ask an adult to help you both?" Mathias nodded, and the mayor told an half-elven villager who runs an pharmacy in the village to accompany the two heroes in their quest of mining rubellite, and she agreed to his request.
The villager introduced herself as Maeve and the two greeted her, with Delilah saying to her "Hi Maeve, are you looking for Blaine and his friends with us too?" She replied "No, but I don't know who they are. Could you please explain to me who is exactly Blaine?" Mathias answered "Blaine is our brother. We share the same mother, but she has been cheating on our brother Paco's father with this one guy, who wasn't our real father."
Maeve said "Blaine is your brother and yet you two share the same mother as him?" Delilah replied "Yes, we share the same mother as him. Like him, she neglected us by beating us up at home with Paco's father and prioritizing him over the three of us to the point we had to run away from the house and stay at an nearby park."
Maeve got outraged over hearing about that from Delilah and told her and Mathias "No time to talk, young heroes, but let's go mine some rubellite!", with the mayor giving the three of them pickaxes to mine rubellite, and they went on a long journey to reach the entrance of the mines in the northwestern tip of Featheria Island.
Upon reaching the northwestern tip of Featheria Island, Maeve, Mathias and Delilah met a strange swordsman, with the former saying to him "Dude, who are you? Why are you here blocking the way for us? The mayor told us to mine some rubellite to repair the bridge in the nearby village, yet you're blocking the entrance to others!" The swordsman replied "If you want to know who I am, you guys better pay me 1,000 feathers so I can let you enter the village. If you don't have enough, then you'll know what I'll do to you."
Maeve said "Seriously? Why do we have to pay a ridiculous amount of feathers? We're not paying for that." He replied "So you don't want to pay? Fine, I'll introduce myself for free." and continuing with "My name is Linden. I'm an average guy who just likes swords, and that's it." only to get spanked by his father who happens to be the mayor of his village with a whip much to Mathias and Delilah along with the villagers' laughter.
The villagers welcomed the three and called them their hero for saving them from Linden, with Maeve, Mathias and Delilah walking to the entrance of the Sigmund Mines, in which they enter the mines. Once they entered the mines, they saw an female orc way taller than them and she wanted to eat the two children for lunch only for them to dig a hole with their pickaxes and put the nails in it as a way to booby-trap her, with her screaming out of anger and them laughing.
The female orc angrily yelled "If I ever see you guys again at our house, then we're gonna eat you for dinner.", and soon, the three heroes stumbled upon a cavern whom the orcs been hiding the whole time and therefore, they encounter the leader of the orcs and they introduced himself to him who reacted aggressively to them and in turn, he ordered the orcs of the Sigmund Mines to get into a fight with the heroes.
As a result, while Maeve tried to defend herself from the orcs, she ended up coughing blood and was almost dying, so the nice orcs carried her to the hospital, leaving Mathias and Delilah alone in the mines and they got lost without any adult accompanying them.
Mathias said to Delilah "Lila, how are we supposed to get the rubellites when Maeve isn't here?!" She answered "Then it's all your fault if we get lost here!" and he replied "No, it was the orcs' fault for almost killing Maeve!", which then soon resulted in an petty argument.
On the airship, Blaine wakes up in a shared cage with only an underwear along with Mayra, and he saw Ostara in her own cage then Silvia and Emil in another shared cage. He said "Are you guys okay?! Why are we all in our undies!?", with Mayra saying "The owner of the airship took off our hanfu because he wants to sell us to some weirdos for profit!"
The scene switches to the poor orc leader allowing Mathias and Delilah to go mine the rubellites supervised by the female orc guardian whom they met at the beginning of the mines, and they got enough rubellites to repair the rainbow bridge, before thanking the orcs for helping them mine the rubellite as well as the villagers for helping them getting revenge on Linden as a result before leaving to the bus crash site.
At the bus crash site, Mathias and Delilah came with a huge bag full of rubellite and they gave it and the pickaxe to the construction workers, who then used it to repair the bridge. The pirate airship who took Blaine and his friends captive appeared again and the two children climbed the rope to save them before flying away with them.
Upon getting into the airship, Mathias and Delilah were armed with their weapons and they encountered the pirates who tried to catch them, but regardless to say, they stole the key to the cages and replaced the gunpowder with the skinny pirates holding what seems to be meth in the airship's cannon which blasted them down to the sky.
However, Mathias found himself surrounded by the remaining pirates and told Delilah to free their brother Blaine and his friends with the keys they stole from one of the pirates in the pirate captain's cabin, and she managed to free them, with him hugging her while crying and he said to her "Who are you?" She replied "Blaine, it's me Delilah, your sister! We've been looking for you!"
Blaine said "Really? Could you find Mathias and bring him to me?" Delilah answered "He's busy fighting the pirates at the moment, so could you please help me and him to fight the pirates?" He answered with "Sure thing, but I need some clothes."
The scene switches to Mathias fighting some of the pirates and after he beat them up, he met the captain of the ship, Elsoyrd who got outraged upon seeing that his subordinates got beaten up by an intruder and they got into a fight with their swords. In the middle of their fight, Delilah found a box of fireworks and replaced the cannonballs with the fireworks on the large cannon, with Blaine, Ostara, Silvia and Emil getting out of the cabin.
Mayra got out of the cabin a minute later, and she saw Blaine, Silvia, Emil, Mathias and Delilah carrying Elsoyrd and putting him in the large cannon along with the fireworks, and Ostara said "Goodbye, Elsword doppelganger! Don't ever come near us again!" before the cannon blasted him away with the fireworks, and then in front of them was a beautiful fireworks display, and Mayra came to see the fireworks with her friends.
After the fireworks were over, Mathias and Delilah whispered to each other about a plan to infiltrate the cockpit in order to put an end to the piracy that has been terrorizing the floating islands of Featheria and Sakurahama since Mayra told them that the remaining pirates were controlling the ship and they still haven't reached their destination yet, so the two heroes went to kick the pilots off the ship and they took control of the ship.
Once they got control of the ship, Blaine, Ostara, Silvia, Emil and Mayra got into the pirate captain's cabin and they threw their cages off the sky before leaving the keys that was used to lock and unlock them, taking a rest there. In the cockpit, Mathias and Delilah summoned a portal to the demon world through a special button.
Back at the cabin, Blaine found new clothes to wear and he gave some of them to his friends Ostara, Silvia, Emil and Mayra, until they heard Mathias' voice saying "Attention passengers! We've now reached Makai. Next destination is going to be the Unfortunate Isles in 30 minutes! Are you ready to enter the Unfortunate Isles?" and the scene switches to him and Delilah arguing over the controls in the cockpit nonstop.
In turn, Ostara yelled to her friends Blaine, Silvia, Emil and Mayra "WE'RE ALL GONNA DIE!" Emil yelled "CAN SOMEBODY GET THOSE TWO BRATS OFF THE SHIP?!" Blaine told the two "Woah, you don't have to scream like that! We'll teach Matt and Lila a lesson!" and Mayra said "I'll do my best to teach them a lesson."
Blaine and Mayra stormed out of the cabin, slamming the door as they went to the cockpit, where they pushed Mathias and Delilah off the pilot seats and hilarity ensues amid the airship until they controlled the ship which unfortunately passed over the Unfortunate Isles. When they came to the cabin, Silvia taught them a good lesson by spanking them and the ship crashed into the entrance of Ignacio's palace.
Luckily nobody got injured, with Blaine and his younger siblings and friends getting out of the airship and they saw the first glimpse of the castle, only for them to get surrounded by the guards.
