The younger sister of Shuutaro, Ryoko is a spoiled girl whose only amusement seems to be the creation and execution of elaborate plans intended to drive her older brother mad.  wikipedia

Urusei Yatsura concerns the tempestuous relationship between two focal characters: Ataru Moroboshi who is possibly the most unfaithful, unlucky and lecherous idiot to have ever been born, and there's Lum, a tigerskin-bikini clad alien package of sex appeal, jealousy and electricity who's fallen for him. The series chronicles the misadventures of these two stubborn teenagers along with a veritable entourage of weird characters. Among these characters is the richest boy on the planet, a superhuman schoolgirl, a fire-breathing baby, a powerful priestess/school nurse, a cute and psychotic alien vixen with a split personality, a gender-bending martial artist, an alien biker chick, an ice queen of Neptune, a deranged monk, a giant ghost cat and hundreds of other lunatic personalities; aliens, humans and inhumans alike interract in endless hysteria in a town named Tomobiki.

The adventures of Lum, Ataru, Ten, and all the gang from Tomobiki continue in an assortment of new &ndash; but no less weird &ndash; stories. 
Watch as Lum, Ataru, and Shinobu encounter a rabbit-clad youth, enter the Room of Destiny, and get a glimpse into their futures in "Inaba the Dreammaker," or see Ran's plans to use a sherbet cone-producing bird to open a sherbet shop one hot Tokyo summer go terribly awry in &ldquo;Raging Sherbet.&rdquo; Ataru has yet another bad experience with Lum's cooking in "I Howl at the Moon".

The story is from manga volume 23. On a very hot summer day in Tomobiki town, Lum, Ataru, and the rest of the gang are looking forward to using the school's pool. But the teachers have other plans: setting a ludicrous obstacle course between the students in their swimsuits and the pool... naturally this ends in complete chaos.

The second season of Urusei Yatsura (2022). 

Lum, the gorgeous daughter of an invading race of Oni Aliens is smitten with High School student Ataru Moroboshi.

What would you do if a tiger skin bikini-clad alien followed you to school every day? Poor Ataru's life has never returned to normal since volatile extraterrestrial princess Lum fell for him. Now an excruciatingly wealthy and genteel rival, Mendo, adds to Ataru's torment. Not to mention an unending stream of extraordinary classroom visitors and educational materials including incompetent cherry blossom spirits, a legendary nightmare-eating tapir, and a fourth-dimensional camera that breeches alternate realities.

When an alien race known as the Oni invade Earth, the chronically unlucky and unapologetically lecherous Ataru Moroboshi is selected as humanity’s representative in a duel for the fate of the planet! His opponent is Lum, the Oni’s very pretty princess, and it’s only thanks to Ataru’s unscrupulous behavior that he’s able to scrape out a win in a treacherous game of tag against her. Ataru thinks he’s had his lucky break at last, but when Lum takes a shine to him off the battlefield, the conflict follows him home as Lum invades not only planet Earth, but also the womanizing Ataru’s love life!
