Sasami is a lazy hikikomori who'd rather be playing video games and sleeping than being a productive member of society, especially with a doting brother who waits on her hand and foot. But there's more than Sasami and her family than meet the eye – in reality, they are connected to the goddess Amaterasu and mysterious 'alterations' that occasionally change and threaten the world. With the help of three sisters, Sasami slowly tackles day to day challenges and puts a stop to alterations – and monsters – when they appear.
Ayumu was murdered by a serial killer – at least, he was. For after the mysterious Eucliwood Hellscythe revives him, he changes from a human to a zombie, much to his dismay. Now, in addition to being unable to die, the boy must see to the whims of his supernatural, silent companion – but things continue to get worse from there. As once Ayumu accidentally steals a magical girl named Haruna's powers, he is tasked with the embarrassing, obnoxious task of being a magical girl – err, boy – in her stead! Then with the addition of a hostile vampire ninja to his household, can Ayumu manage to maintain his new home life, fight against attacking monsters, and track down the person who killed him all while attempting to keep what little dignity he has left in tact?
Both series feature a rather extensive mostly female cast and play parodies and otaku culture as straight parts of their worlds. The humour and fan service is quite similar at times. Sasami is rather artistically made so in the first light it might look different however it does have quite a couple of overlapping content a quarter of the way in.
Sasami is basically kore wa in a shinto setting without the harem setting sharing a lot of humour while still retaining a plot.
If you liked either of these over-the-top shows, I suspect you'd like the other. They're both about people & families with supernatural powers who really just want to live normal lives, and they both have a similar crazy atmosphere with a comedic take on existential themes.
Kamba and Shouma Takakura have taken care of their sickly younger sister Himari since their parents disappeared years ago - that is, until the day she died. But as the boys grieve by her hospital bed, Himari sits up, adorned with a strange penguin hat. Suddenly, the three of them are transported to a vibrant world where the hat, using Himari's body as a puppet, charges these brothers with a task: find the Penguin Drum and their sister's life will be saved! Now aided by some odd penguins they received in the mail, the duo must find this mysterious item or risk losing the sister they care for so much. However, they aren't the only ones with their sights on the Penguin Drum, for new enemies await them around every turn, all connected in ways they would have never imagined...
These shows have a lot in common: unusual animation styles, a host of excentric characters including brother(s) and sister(s) who are perhaps a little too close and a modern setting with world-altering fantasic powers.
Sasami-san tends towards the over the top comedy while Penguin Drum tends to be serious and dramatic but both shows are a blend of serious and funny moments.
Izumiko has lived a secluded, sheltered life in a mountain shrine since she was born. Having been raised to become the vessel of the Hime-gami, a mysterious force, the girl’s family has carefully planned and measured all aspects of her life - from the prestigious school she’s meant to attend to even her hair style. So when Izumiko is threatened by strange events, her father forces yet another obligation on her: Miyuki Sagara, a mountain monk descendant who’s fated to be her bodyguard. Unfortunately for the duo, neither is happy about the arrangement, especially Miyuki, who’s being exiled from his home city to guard a girl he considers to be useless. Can the two learn to find common ground in their search to understand the supernatural mysteries unfolding around them?
Both series focus on a young girl with the powers of a god. In Sasami-San, most of characters contain the powers of gods but in RDG, most of the characters are basically priest, monks and socerers. Both series revolve around Japanese spritual beliefs. While true that both series have a slightly confusing plot, there both highly enjoyable when you decide to watch them all the way through.
The eccentric Suzumiya Haruhi wants nothing more than to meet aliens, time travelers and espers… but she’ll have to settle for the everyday Kyon instead! Along with the mysterious Itsuki and the vacant Mikuru, the duo forms the SOS Brigade – a club whose mission is to discover the mysteries of the world. Armed with a razor sharp wit and a skill for manipulation, Haruhi will stop at nothing to have fun at all costs, even at the expense of Mikuru’s dignity!
While Haruhi is far more spastic and based on comedy, both titles feature similar main characters who are obnoxious in their own way, with special powers involved in the cast, etc. They definitely have a similar feel, drama/comedy differences aside.
