The original storylines of these comic series bear little resemblance to what later became famous.
1. The Promised Neverland

We Were Born serves as a precursor to The Promised Neverland. In this segment, the author introduced a gangster named Leo who rescued a girl named Rina from the clutches of her foster parents. Initially, this story seemed somewhat unrelated to the main plot, although they shared a common theme.
We Were Born was drawn to suggest that every life has meaning and every individual has the right to choose their own path. Although the storyline has been altered, fans may still sense similar emotions to those in The Promised Neverland.
2. Haikyuu

Debuting in January 2011, the one-shot chapter of Haikyuu spans 51 pages and introduces some intriguing differences compared to later releases. Instead of Hinata taking the spotlight, Kageyama now emerges as the central figure.
The one-shot portrays a completely different Hinata - a boy who doesn't love volleyball but possesses exceptional athletic abilities yet lacks enthusiasm for joining a team. Additionally, a quirky aspect of this version is that Hinata is not short.
3. Attack on Titan

The prelude to Attack on Titan is vastly distinct from what fans know of the renowned Titan conflict that unfolds later. Fundamentally, the plot still revolves around the battle between humans and Titans, with warriors capable of transforming into Titans. Perhaps the most significant difference lies in the setting.
In the prelude, humans have constructed a city within the forest instead of colossal walls. They believe that Titans cherish nature and would not destroy the greenery to harm humans. While the concept deviates slightly, the core narrative remains largely unchanged as Titans remain a looming threat to humanity.
4. Kuroko no Basket

The one-shot chapter of Kuroko no Basket was released in spring 2007. The storyline remains closely aligned with the official version, yet there are a few subtle changes. The most significant alteration in the plot pertains to Kuroko's title as the 'phantom sixth man' in the miraculous generation.
In the one-shot, Kuroko lacks the title of 'phantom' and is considered a member of the talented generation like the rest. This significantly alters the aspect of Kuroko as a phantom player.
5. Death Note

The Death Note one-shot story follows Taro Kagami, a 13-year-old boy who mistakenly regards the deadly notebook as a diary. After writing the names of some bullies in the notebook, Taro inadvertently kills a few kids who had been bullying him.
In addition to the notebook's power, this part introduces a deadly eraser capable of reviving those killed by the notebook. The story concludes with the notebook being burned, and seven years later, Ryuk and Taro hear rumors of the notebook reappearing somewhere in the world.
