There comes a time that a manga has to end, no matter how popular or beloved it is. That's become more and more of a difficulty nowadays as certain series look like they are never going to stop and a constant stream of sequels seems all the rage now. Even Inuyasha recently received one, along with the Burn the Witch spin-off from Bleach. It's hard to leave well enough alone.

At times, a manga sequel can end up striking gold, as Dragon Ball Z was a great follow-up to Dragon Ball, and even some of the more recent follow-ups have been solid as well. That can't be said about them all, however, with many failing to live up to their predecessor.

10 Fruits Basket: Another

There's no debating how amazing the original manga was, with Fruits Basket being seen as a masterpiece to many, earning all of the accolades it gets. The story was so intricate, deep, and creative that you couldn't help getting drawn into it.

The same can't be said of Another as it feels more like an epilogue than a true spin-off, falling into the issue of being too much like it's predecessor and failing to bring anything new to the table. Everything about the manga feels like a retread, going through the motions everyone already went through in the original.

9 Saint Seiya: The Lost Canvas

Sometimes something can be a failure without managing to be actually bad. On its own, Lost Canvas is a pretty enjoyable series and one that eventually got beautifully animated. It also ended up selling fairly well. The issue is that within the sphere of Saint Seiya's story, it's an utter failure.

It completely diverges from the plot, creating a massive "what if?" series that can leave new readers confused if they mistakenly think it's canon. Going noncanonical isn't always bad, so long as it dives into a different genre as was done with Naruto's Rock Lee spin-off series.

8 Daiya No B!

It only recently received an anime adaptation, but Ace of Diamonds has long been a popular sports manga and one of the most well-known that centers on baseball. Normally sequels would try to carry on the story past the point it needed to go, unwilling to tie a bow on the series.

Daiya no B doesn't do that, and instead, it keeps all of the same characters— but instead of having them play baseball, they are all in a brass band instead. It's such an out of nowhere change that it's a wonder whom the author was hoping to appeal to. Not only would is it rehashing the same story in a new setting, but it's also in one that doesn't even mesh with the original.

7 Yu-Gi-Oh! R

Tea gets Possessed by Shadi Yu-Gi-Oh!

Did anyone ever ask for a series where Anzu (Tea) was going to be a main character and a vital part of the storyline? If so, this is the manga for them as it takes place not only in the same universe as the original but right in the middle of Battle City and the Millennium Worlds arcs.

It follows Yako Teman, a protégé of Maximillian Pegasus, as he attempts to bring his mentor back to life through the body of Anzu. The entire plotline is absurd, even by Yu-Gi-Oh standards. It's disputed if it's even canon due to the inconsistencies in the timeline and how awful the story was.

6 GTO: Paradise Lost

Great Teacher Onizuka is one of those gems that many tend to overlook, a classic example of a delinquent style character growing as a person and helping reform those around him. His motives at first were shifty, but watching him bloom as a person made for an incredible series.

A lot of that gets tossed to the wayside in the sequel, however, as it starts with him in prison, regaling the inmates with the tale of how he got there. It goes back on a lot of the progress he made throughout the series and doesn't jive with the message it conveyed.

5 Kyo Kara City Hunter

City Hunter: Shinjuku Private Eyes

City Hunter is one of those classics that never properly got its due as its run came to an end just as manga and anime were becoming more popular, not letting it ride any of that wave. It follows a Lupin The 3rd-styled character named Ryo Saeba as he runs his City Hunter business.

The manga was so successful that it even spawned two sequels in Angel Heart and Ryo Kara City Hunter. Unfortunately, Kara doesn't have any of the charms the original did and was darn right weird, even by the manga's standards. Having a fangirl of the series die and be reincarnated within the City Hunter universe was just a silly premise all around,

4 Major 2nd

An image from Major.

There are times a series and the story it was meant to tell hits its expiration date. That's what happened with Major, a series that followed Goro Honda from the beginnings of his life in kindergarten to him rising up to become a professional baseball player. It's a timeline few series adhere to, letting you truly grow right along with Goro.

A lot of that shine wears off in the 2nd, with Goro now a father and more of a background character for his son, Daigo, who isn't nearly as interesting a character as his father.

3 Kinnikuman Lady

Ultimate Muscle

Ultimate Muscle was a strange show and even odder manga. It followed Kid Muscle, the son of the first Kinnikuman prince of Planet Muscle, and shows his progress as a man. It was the one sequel series that was a worthy follow up to the original Kinnikuman.

But the same can't be said of Kinnikuman Lady, which simply reimagined the main character as a woman. It started as a webcomic but eventually got picked up by Ultra Jump. The whole series felt rather lazy, and more of a rehash of stories rather than a true sequel to the series like Ultimate Muscle did.

2 LI Yu Da Ne! (What A Nice Bath!)

Kochikame Manga

Kochikame is the longest-running manga series in the world and one that not everyone has heard of. Despite topping out at over 200 volumes, it's never been as popular in America as it was in Japan, possibly due to its 1976 start date and the content within.

It's a gag-filled anime that follows Ryo-San as he tries to capitalize on whatever the big new fad is at the time and unsurprisingly running into trouble. It's a comic that did a great job poking fun at the fads Ryo-San pursued, doing it in equally zany ways. Sadly, the sequel didn't have the same zippiness to it, feeling a little long in the tooth.

1 Boruto

Boruto shocked

When thinking about disappointments, no manga pops out right away quite as much as Boruto does. It isn't that Boruto is necessarily a bad manga— there are good things in it, and it can be enjoyed. It still sells well, so that isn't an issue, but even its biggest fans can admit that it's not as good as Naruto was.

When you have the ghost of one of shonen's big three hanging over you, there needs to be something that sets it apart, and Boruto simply doesn't have that. When the most enjoyable characters in your series are all the ones that carried over from Naruto, you know you have issues.
