Lilietta models a new product. It's an armor with a charm effect.
Kautz has no mana, and is instantly smitten. Narden offers him a protective ribbon (as any who plays Final Fantasy understands,) but he rejects it as too feminine and picks up a completely ineffective one instead.
Lilietta has massive strength; she has to wear enchanted gloves to restrain herself.
Kautz takes the second spare room above the shop. Upon realizing that he and Lilietta will be living together, he has all kinds of fantastic delusions.
Narden tells how, when he was young he was an upcoming Genius Wizard, until he was defeated by the Sexy Knight, Rose Löhe, and became her apprentice. He worked diligently for twenty years to craft the Genuine Armor.
Kautz dives in front of the Demon lord's attacks to protect Lilietta.
Lilietta dons the genuine armor: by combining the softness of an angels feather with the softness of a girl's breasts, it overflows to maximum hardness: complete impenetrability.
Things get even less explainable when the gang investigate a giant anime store that has opened in town, get sucked into a featureless room, cosplay, and fight a man with a cube for a head.
While adventuring for reagents, a mysterious talking armor falls from the sky. After calling everyone in the store a pervert, she makes her home on Lilietta's head.
Kautz uses the sexy ray to turn everyone back into an adult again. Flearika evolves for an arbitrary reason. They spend all the animation budget for the season on a battle. They break the fourth wall to acknowledge it.
Mamori puts herself in the way to save the others.
Mamori evolves into her final battle form. Taking control of the opening, she and Lilietta literally fling the credits at the villain until her spell breaks and the world is restored.
Narden determines this was never his real master, but was Mr. Wholesome all along.
The animators tease you by having a bath scene with Flearika and Lilietta, but focussing the camera on Mokuku the whole time.
The Demon Lord, in the shape of a young girl, arrives and demands that Narden return the Angel Wings he stole from her.
