Smile of the Arsnotoria the Animation - Season 1

Heine Wittgenstein is a pint-sized man given a monumental task. He's recently hired by the King of Grannzreich to whip four of his five sons into royalty material as their tutor.

Two kids whose families own businesses in a shopping arcade that's scheduled to shut down are thrown into a series of dimensions, each one a parody of some form of anime or video game, and try to find their way home.

The Summer of "Anu": In a summer once every five years, demons in the mysterious Tower of Druaga lose their powers due to the magic spell cast by a god named "Anu". King Gilgamesh, ruler of the kingdom Uruk, uses the appearance of demons as an excuse to invade the tower and find out the construct's secrets. As 80 years passed, the Uruk army managed to fight back the demons and built a fortress city and safe haven on the very first floor of Druaga—Metz Kier. Thus begins the story of a warrior named Jil, who, finding companions along the way, embarks on a quest for the fabled Blue Crystal Rod, a powerful artifact rumored to be in the highest floor of Druaga. However, other competitors, including the kingdom of Uruk itself, want the treasure, all for their own reasons.

In the decade since the world became aware of the existence of magic, the world has undergone massive upheaval. However, a boy named Tōta lives in seclusion in a rural town far removed from these changes. His ordinary life is highlighted by his magic-using female teacher and his supportive friends.

Ko Ichinomiya's family motto is "Never be indebted to anyone," but after losing his pants and falling into the Arakawa River, he quickly finds himself in debt to his savior, the cutely insane Nino who happens to live under the bridge. To repay her, he vows to help her with her desire to "experience love." Along the way he'll meet the river's other residents, including a hot-blooded kappa, a Sister in drag, and a literal rock star.

Amamizukan is an apartment complex where no boys are allowed. Tsukimi, a girl who adores jellyfish, lives there happily with her friends who all have nerdy obsessions of their own. Their peaceful lives gradually start to change when a beautiful woman helps Tsukimi out of a pinch. She stays overnight at the apartments—but it turns out "she" is really a "he".

High schooler Yūta Iridatsu has experienced “astral projection” i.e. his spirit has been separated from his body. He woke up in a mansion named Koraikan and met a cat spirit named Chiranosuke, who told him “You must find the Sacred Tome of Koraikan in order to return to your physical body.” While searching through corridors of Koraikan, Yūta bumped into underpants of its female residents, and doing so would, eh, create some big trouble for planet Earth.

Social worker Mark Lilly helps new citizens—both human and "other"—begin the process of adapting to life in the Big Apple, but his coworkers, demonic bureaucrat Twayne, drunken wizard Leonard Powers, surly law enforcement head Frank Grimes & his girlfriend, Callie, don't make it easy.

16-year-old Hayate is really down on his luck. Because his unemployed parents are good-for-nothings who waste what money they have on gambling, Hayate had to start working at a young age to help out his family. Although such experience has made him inhumanly fast and tough and skilled at things boys aren't normally skilled at, it has also left him in an awkward position, as his parents have racked up such a huge gambling debt that they have sold Hayate to the yakuza for the value of his organs. In a desperate attempt to avoid that fate, Hayate decides to become a "bad guy" and kidnap someone to be held for ransom, but his efforts to do so are mistaken as a confession of love by the girl he targets. When he helps save the (as it turns out) ultra-wealthy 13-year-old Nagi from real kidnappers, she takes him in and gives him a job as her new personal butler (and love interest) until he can pay off his debt. But Hayate is more attracted to Nagi's beautiful teenage maid Maria, and head butler Klaus is initially disapproving of a boy with such a poor look. And then there's Nagi's pet Tama, who is also a force to be reckoned with.

The surreal adventures of three anthropomorphic fast food items: Master Shake, Frylock and Meatwad, and their human nextdoor neighbor, Carl Brutananadilewski.
