Evening of the Meteor Storm
The city of Ert' Aria is busy with preparations for the festival of the shooting stars, a meteor shower that happens only once every seven years. Carina Verritti arrives early at the house of Clan Oasis, hoping to rouse Leicester Maycroft from his bed, but Leicester is already awake, and must find a way to console her. The two head out to the market where they see a performance by the magician puppeteer Agnes Boulange. Agnes calls Carina out of the crowd to volunteer as her assistant during the performance; afterwords, she joins them for lunch. At the restaurant, all three notice a striking young women marching with the Holy Knights who is later revealed to be Chelsea Arcot, an acquaintance of Leicester's mother, Shelly. Both Agnes and Chelsea agree to join Clan Oasis at the viewing party on the cathedral roof. En route to the cathedral, the party runs into Ritos and Salsa Tortilla, who publicly argue over which will be Leicester's bride, but decline to join the party, claiming to know of a better "higher" viewing spot. Carina and company finally make it to the roof, where they watch the falling meteors. One appears to be heading directly towards them and harmlessly strikes one of the spires. Leicester chases after it, but finds a girl (Minette) lying in bed, who awakens and calls him Papa.
World of Dragons
The clan accepts a quest from Carina's father, Grand Duke Fabious. Fabious has detected a dangerously strong concentration of El, the magical substance that brought Minette to life, in his treasure chamber, and wants Oasis to remove it. In the treasure chamber, Chelsea senses the El behind a locked door said to lead to the realm of dragons. Carina uses her magic to unlock the door and the group passes though to a forest where they are immediately attacked by a crystal monster in the form of a dragon. No one, including Ritos and Salsa, who try to steal a march on the group, is able to defeat the monster until Minette, who came along despite Leicester's objections, captures its magic by means of the anima perla. A real dragon in the form of a girl who calls herself Garnet appears and gives Minette a glowing red and yellow sphere in thanks. The episode ends at the beach, where Leicester must think quickly to avoid offending any of the girls when asked to choose which has the prettiest swimsuit.
The Staff of Bonds
Arriving at Oasis house, Carina is taken aback at the sight of Leicester and Agnes engaged in deep conversation. Leicester deflects her inquiry by changing the topic to light-absorbing rainbow flowers, and convinces the clan to undertake a quest in search of some. The group quickly becomes separated in the woods, with Leicester and Carina flying ahead on her staff. Ritos and Salsa intrude once again, but accomplish little. Before the rest of the group can catch up with them, Leicester and Carina battle and defeat a crystal monster hiding in the darkness of the rainbow flowers. Carina flies up to retrieve a crystal left in the tree branches and plummets towards earth when her staff suddenly runs out of power. Leicester attempts to break her fall, but the two become entangled in vines and must remain in an indecent position until rescued by the rest of the group. Back in town, Leicester reveals to Carina that he was consulting with Agnes over how to give Carina's staff the ability to talk, and was told that El must be bonded with strong emotional bonds. Carina and Leicester work through the night attempting to accomplish this, and eventually succeed in creating an outspoken talking staff.
Within the Darkness
Agnes strikes out on her own, but after encountering an old favorite patron, returns to enlist the clan in a hunt for bath crystals. Ritos and Salsa hear of the quest, but misunderstanding, assume that the group is making a trip to an onsen. Leicester, Nick, and the girls enter an abandoned mine to search for bath crystals. They find quite a few, and after breaking for lunch, Agnes and Leicester scout on ahead, discovering a mysterious shrine built around a large crystal. Everyone enjoys bathing in the light of the crystal, but an earthquake sends them scurrying for the exits. A rockfall isolates Agnes and Leicester from the rest of the group, forcing them to find their own way out. The clan reunites outside the mine and celebrate their success by giving Ritos and Salsa some of their extra bath crystals. At home, Shelly pulls a prank on Leicester by sending the girls to the bath before he is finished. Agnes and Leicester end up hiding naked in a corner, hoping not to be discovered by the other girls.
A Day Off at Oasis
Minette goes shopping, makes a friend, rescues a cat, and loses her skirt. Ritos and Salsa supervise from behind the scenes. Leicester comes to the rescue. Chelsea and Garnet get lost.
On the Night of the Party
Shadowed by Minette, Leicester admires Chelsea sparring after making a delivery. He invites her to a party hosted by Fabious in honor of the Holy Knights. The girls try on party dresses. Nick and Leicester replace the knights guarding artifacts in the cathedral, and the Tortilla sisters provide security for the party. A crystal monster attacks the party and is defeated by Leicester and Chelsea as the adults gossip upstairs. They are particularly concerned about the increasing concentrations of El and the corresponding rise in the number of crystal monsters. In the end, Chelsea drinks too much and has to be carried home and put to bed by Leicester.
The Puppet Forest
Oasis is hired to investigate the preponderance of El. Why do meteors continue to fall long after the shower was supposed to have ended? In search of answers, they travel to the workshop of Mise Altoise, the builder of Minette and Agnes's teacher. Despite signs of her recent presence, Altworth is nowhere to be found. After considerable sleuthing, Oasis finds a letter addressed to Agnes from Altworth that says she has gone in search of an artifact. They have no time to reflect on the meaning of this, as the group is immediately attacked by a mysterious duo trying to take Minette's core. Agnes recognizes Avril and her own older brother Aberdeen, but they vanish before she can call them to account. Ritos and Salsa make a cameo.
It's Episode 8, You Know! Everyone Gather Together!
Ritos and Salsa are hired to protect Minette while preparations are made for the Harvest Festival. Their "protection" includes convincing Minette to promote the Tortilla Company in a bikini. Ritos plays multiple tricks on Salsa throughout the episode, but her scheme to set up her sister with Leicester falls through when Salsa refuses to be separated from her twin.
Signs of Abnormal Changes
Oasis continues to investigate. Miriam collapses while playing with Minette. Garnet, knowing her for an automaton who is no longer human, sends Agnes to help. Agnes says that Miriam will die if she cannot get a new core, and that the only suitable replacement is Minette's anima perla. Aberdeen storms the bedroom where his sister Miriam is resting, only to be confronted by Leicester and company.
Aberdeen takes Miriam back, but not before she protests that Minette should not be sacrificed for her sake. As Miriam fades, Minette lives life to the fullest. That night, Minette runs away from home after bidding Leicester good night. Shelly catches up with her on the cathedral roof, and lets Minette cry in her arms but does not stop her. The episode ends as Leicester notices that Minette is gone and rushes out in search of her.
Aberdeen brings Minette to Miriam's bedside and gets ready to transfer the core, but Carina magically locates them before he can finish. Carina battles Avril while Leicester fights Aberdeen. Avril and Aberdeen possess mighty battle artifacts and cannot be defeated, but Leicester and Carina are also strong. A particularly large flash draws Minette out from the house: when she sees Leicester and Aberdeen fighting, she interposes herself. Miriam follows and begs everyone to work together and find a way for both of them to live. Leicester and Aberdeen agree to do so, but Garnet suddenly appears calling everyone back to town. The unregulated flow of El is reaching a crisis point and everyone must work together to save the world.
Blessing of the Campanella
Leicester and company go off to fix the unregulated El. Ritos and Salsa guard the home front, Avril and Aberdeen fight a rearguard action, Nick and Garnet keep the stairs clear, Carina, Chelsea and Agnes watch Leicester's back. Altworth releases the artifact, ending the creation of crystal monsters but exposing Leicester to its full flow. With Minette's help, the artifact is restored. Nina prepares for a party.
