When Hayate was young, Santa appeared in a dream and told him that if he worked hard, he’d be rewarded. Thus, with an unbreakable will, the unfortunate Hayate has struggled through life holding onto that belief. In the present, his parents are lazy and unemployed, forcing Hayate to work several jobs to pay the bills. As if things couldn’t get worse, Hayate’s parents then run away, leaving him with an enormous debt and loan sharks on his tail! Naturally, the best solution to find money fast is… to kidnap someone?! A girl named Nagi is the target, but due to an unfortunate miscommunication, she believes Hayate has proposed to her and falls for him hard. After Nagi paid off his debt, Hayate must now work as her butler in order to repay her; but first, he must adapt to her wacky world!
To make money, high school student Shinkurou Kurenai works for the secretive Benika as a "dispute mediator," acting to intervene in the disputes of clients – often violently. One day, Benika gives him a much different assignment: to protect Murasaki Kuhoin, a seven-year-old girl from the wealthy Kuhoin family. This turns out to be a more troublesome task than he expects, as Murasaki is spoiled, naive, and completely unaware of what life is like outside of the luxurious one she had previously. He also has no idea why Murasaki needs his protection, though he is slowly obtaining details from a well-informed classmate. Adding to his problems, Shinkurou still must continue to do his previous work for Benika and take care of his social relationships in school while protecting Murasaki, complicating his entire life. Nonetheless, as time passes, he and Murasaki grow close; however, trouble brews in the shadows as everyone - including Shinkurou - seems to be harboring secrets...
It seems a sort of absurd comparison, but I think that these two shows are similar in enough ways to find enjoyment in both if you like one. On one hand, Hayate is mainly a comedy and Kurenai mainly a drama, but the idea of taking care of a young naiive girl stands prevalently in both. Both Nagi in Hayate and Murasaki in Kurenai have that quality of naiivete in the same way and I think you can draw enough parallels between them to enjoy both shows.
Satoshi and Arumi have been friends since early childhood, but now Arumi's family is moving to Hokkaido, deeply upsetting her long-time friend. However, when Arumi's grandfather accidentally breaks the pelican statue atop his restaurant, the duo find their world turned upside down and not quite as they left it. From a fairy tale kingdom, to kung fu China, to the prehistoric age and everything in between, Arumi and Satoshi can't quite seem to figure out where they are, or better yet, how they can manage to get home to their own Abenobashi Shoutengai!
Miki is a psychotic mascot, waitress and delivery girl who works at her equally as frightening mother's ramen shop. Both survivor and instigator of years of ruthless, no-holds-barred domestic violence, Miki has a capacity for destruction usually found only in people with things like "the Impaler" added to their name. Yet, she also has a kind side to her and is often found going implausible distances out of her way to rescue both proverbial and literal lost kittens, though some malignant souls might misconstrue this as merely ditching her work...
I personally believe that if you like one of these you will like the other. Both of these anime have characters that have super ultra mega strengths and abilities that usually is only slotted for Dark Lords or Ninjas. But not in these anime, oh no, these powerful people are a Ramen Waitress (Miki) and a Butler (Hayate). Makes sense right? Also, the humor is side splitting amusing and random and very slapstick in both of these anime. If you like slapstick humor and random fun and people that have abilities that they should have, then either of these are for you!
When Kaede, a girl frustrated with her grades like any other teenager, finds a female Ninja attempting to steal her underwear, she didn't expect a friendship to be the result. And as the modern day world of ordinary high schooler Kaede collides with Ninja-in-training Shinobu, she soon comes to discover that the world of modern day Ninjas are filled with parties, picnics, and the training of the elder master Ninja yellow form changing glob: Onsokumaru!
Though Hayate the Combat Butler and Ninja Nonsense have little in common plot-wise, both titles show a love for randomness and parodying popular genres. They also tend to break the fourth wall from time to time. So, if you liked the fast-paced jokes and overall humour of one of the shows, you'll probably like the other.
As Yuuto continues to keep Haruka’s otaku nature as much of a secret as possible, chaos continues to surround them. With Yuuto’s wild, drunken housemates gatecrashing their trip to a hot springs resort, and Haruka’s sister and maid team concocting various schemes to allow the pair to spend time together, nothing is ever straightforward. While Yuuto does all in his power to make Haruka happy, including working as butler for the tyrannical Touka and pulling an all-nighter to help her finish her first doujinshi, he is unsure as to how the school beauty feels about him. Will the clueless duo finally be able to muster up the courage, and the time alone, to finally confess their feelings for each other?
These two anime are similar in the way that they both are romantical comedies featuring a boy who is being forcefully dragged in the "otaku world" by a wealthy young girl. The humor is quite different in each series but you'll surely enjoy one if you liked the other.
