However, an unusual distraction presents itself one unsuspecting day in the form of Chii, a robotic young girl that has been discarded in the trash. In a world where an increasing number of people turn to these 'persocoms' for company, the bonds and limits of human relationships are tested as flesh manages to fall in love with the machine itself...
While trying to protect a wooden relic, high school student Yuuri Mito summons the Goddess Kikuramikami no Hime in the form of a sweet, affectionate child; she begins to live with him, taking the name Mashiro. Yuuri promises to marry her when she grows up, which unfortunately for him happens overnight! However, they soon have bigger things to worry about, as the relic is accidentally destroyed, unleashing the Tayutai, a human-hating race of monsters. Along with Yuuri's childhood friend Ameri, his step-sister Yumina and Mifuyu - an honour student at Flawless Girls' Academy - Yuuri and Mashiro must step up to fight the Tayutai, protect the world, and even learn about underwear!
Both of these are romance ecchi shows with similar humor. Also, Mashiro and Chii are quite similar because they lack common sense and knowledge of the world. Their love interests are both below average guys.
Chobits and Tayutama -Kiss on my Deity- are romantic shoujo types of series that have a similar echi type of humor. The main female characters have a lack of common sense that creates quite a hilarious mood in certain situations.
“Vash, the Stampede” - worth 60 billion dollars to the one who can turn him in. Bounty hunters everywhere are on the lookout for this legendary gunman, not to mention insurance agents Meryl Stryfe and Milly Thompson, who are tasked with preventing any potential damage that this Vash can cause. But with 60 billion on his head, Vash is not an easy man to find.
Even though the tone of these anime's are decidedly different both begin with a light comedic tone and then shift to a much more plot and character heavy conclusion.
Tatsuhiro Sato is a university dropout and a "hikikomori" – a person suffering from social withdrawal. To Sato’s dismay, his self-imposed exile from the world is rudely interrupted when a mysterious girl knocks on his door. She has charged herself with the task of curing Sato of his hikikimori ways! Now, as new problems ranging from hentai games to internet suicide spring up, can Sato manage to overcome his hermit-like ways, or will the imaginary N.H.K conspiracy force him to remain a hikikomori forever?
Chobits and Welcome to the NHK share very similar humour and story arcs of troubled love; all be it NHK is a far darker and "HardCore" in story and tone then Chobits.
Welcome to the NHK! and Chobits have a lot in common, everything from the sweet girl that overlooks the shortcomings of a guy who's pretty much a loser, to a lot of the comedy style. They even have similar episodes, which I would guess means NHK borrowed a lot from Chobits.
Either way, they are both sweet romantic comedies that make you feel good and gives the guy that normally goes through life alone a chance to find love.
Goro Mutsumi is a young man that never seems to catch a break; he has a hard time keeping a job, has horrible luck, and continuously finds himself in bad circumstances.

They're the reincarnated angels of his deceased pets, and they're here to turn his luck around given how well he treated them in their past lives.

One thing's for certain: Goro's life will never be the same!
