Shonen series are undoubtedly the most popular anime and manga demographic. The story is aimed primarily at young boys and contains many exciting battles and powerful stories. That said, shonen series come in many different flavors these days, and it's gotten to the point where many of the main shonen are actually mistaken for seinen by many. For some reason, some fans think that all “serious” anime series are actually coming of age, but that's not really the case at all. The classification of comics is based on the magazine in which the comic was serialized. Out of all the boys, quite a few have been confused about seinen at least once.

Magazine currently being serialized: Byeolchae Boy Magazine
If there's a major recent series that many fans confuse as Seinen, it's definitely attack on titan. Many fans are under the impression that: attack on titan seinen and mostly this is due to their more mature nature. Attack on Titan is a very gruesome series and features titans that eat humans. Creator Hajime Isayama does not hesitate to show these creatures eating humans.
Isayama is not afraid to kill important people in brutal ways. attack Titans also explores more political elements than the average boy. The Marley arc and everything that followed certainly made many people feel like the series was aimed at an older audience. However, what happened in the story is secondary to what magazine it was published in, and when it comes to classification, Attack on Titan was published in a separate Shonen magazine, making it Shonen.

Magazine serialization: Weekly Shonen Jump
The Promised Neverland A legendary shonen series that many believe is actually Seinen. As with any series, it comes down to how brutal the story is. The Promised Neverland started off on an intense note as it was quickly revealed that the children raised in the orphanage were actually raised as livestock to feed demonic creatures.
The story begins almost like a horror thriller, as the children try to create an escape route for themselves to survive the terrible fate of being turned into butcher meat. The story is brutal, but he's still a boy. The Promised Neverland was published in Weekly Shonen Jump and remains one of the magazine's most iconic series.

Serial magazine: Monthly Shonen Jump, Jump Square
claymore This is a series loved in the 2000s. Many people compare Claymore to the Seinen series Berserk. Although these two comics are similar, they each fall into different demographics. In fact, this is one of the reasons why some fans started referring to Claymore as “Boy Berserker.”
Most fans still don't know the boy classification. Like many other Shonen series combined with Seinen, it's because of the themes and creepiness of the source material. Claymore follows the story of Claire, a half-yoma, half-human female warrior who must fight and kill shapeshifting creatures that feed on humans. Claymore battles can be very intense and violence is clearly visible. It definitely feels like a more mature series, but it was eventually published in two shonen magazines: Monthly Shonen Jump and Jump Square.

Magazine serialization: Weekly Shonen Jump
There weren't many animated series in the 2000s that were as iconic and beloved as this one. Death Note. Death Note took the world by storm, and the dynamic between L and Light is undoubtedly legendary. That said, fans might be surprised to learn that Death Note is not a Seinen manga or anime series. Instead, it is a shonen manga from creators Tsugumi Ohba and Takeshi Obata.
It is the dark theme of Death Note that leads many people to believe that it is a seinen manga. There are many tragic and gory deaths in the Death Note series, and the series is extremely serious, leaving no time for jokes or light-heartedness. Through Death Note, Light killed many people in brutal ways. It's no surprise that many people believe the series is aimed at an older audience. This is especially true if you look at the fans. In other words, Death Note, along with One Piece, was serialized in the most iconic shonen magazine, Weekly Shonen Jump.
Chainsaw Man

Creator: Tatsuki Fujimoto

Magazine serialization: Weekly Shonen Jump, Shonen Jump +
Chainsaw Man It has confused quite a few fans when it comes to classification, but it is undoubtedly a shonen series, although some elements seem to lean more towards Seinen. Chainsaw Man follows Denji's story, and the story features demons and psychological horror. In particular, Makima, the main antagonist of Part 1, appears. Chainsaw Man is definitely more serious than the other boys. It also contains violent and extreme sexual content, which is not common in shonen manga. Once again, none of that matters because Chainsaw Man was serialized in Shueisha Weekly Shonen Jump. It was later moved to Shonen Jump+.

Magazine serialization: Weekly Shonen Jump (parts 1-6), Ulta Jump (parts 7-9)
jojo's bizarre adventure This is a bit unique when it comes to categorizing comics. Many people think that Jojo all falls into the Seinen category, but that's not exactly true. To be clear, some parts of Jojo's Bizarre Adventure fall into the Shonen category, while others fall into the Seinen category.
Currently, Jojo only has Seinen parts, starting with Part 7 after the story reset. Meanwhile, Parts 1 to 6 are all boys. This discrepancy is due to magazine switching in Jojo's Bizarre Adventure. Parts 1 to 6 of JoJo were serialized in Weekly Shonen Jump. Meanwhile, JoJo has been serialized in Seinen Magazine Ultra Jump since his debut in Part 7. JoJo has always dealt with mature themes, and the stories didn't change much even after switching to Seinen magazines. There are even humorous moments still present. After all, Cao Cao always had his happy moments, followed by cruel and serious incidents. The story behind Weather Report is one of many examples showing that Jojo has always had dark storylines, even before his transition to Seinen magazine.

D. Gray Man This is a representative manga by author Katsura Hoshino. The story began in 2004, and while it's still technically a work in progress, the rollout is slow. Many people believe it is the seinen,m series and there is definitely confusion as to why. This story has always had a darker tone. Since it's set in the 19th century, much of the animation takes a darker turn for the series. The plot is also more serious than that of an ordinary boy due to the battle between the Exorcist and the Black Order.
With this in mind, D. Gray Man is still a shonen series and was mostly serialized in Weekly Shonen Jump magazine. The series has since turned into several magazine releases, but has remained a boys' magazine for young boys to read.
