A harem anime or manga usually referred to a plot in which there were many male and female characters who loved each other, were ambiguous, or had sex. This plot was often called "harem" or "multi-angle love."
This kind of anime or manga works often focused on the design of harem plots through the interaction between multiple characters to strengthen the storyline and character to enhance the emotional resonance of the readers. At the same time, harem anime and manga often involved competition, misunderstanding, reconciliation, and other plots between characters, which increased the complexity and interest of the story.
Common harem anime or manga works included Harem Academy, Sailor Moon, Magical Girl Little Yuan, Tokyo Ghoul, and so on.
The Chainsaw Man anime goes quite a way into the manga, but it doesn't include everything. There are some parts that are exclusive to the manga and haven't been animated yet. So, if you're a die-hard fan, don't miss out on the manga!
It depends on personal preferences. Some people think the manga has more depth and detail, while others like the animation and voice acting in the anime.
In my opinion, both have their merits. The anime brings the story to life with dynamic action scenes, but the manga allows for more in-depth exploration of characters' thoughts and emotions.
For me, the manga is better. The art style is unique, and you can imagine the scenes exactly as you want. The anime, though well-made, sometimes doesn't capture the same raw emotion as the manga.
In general, the One Punch Man anime is very close to the manga. It successfully captures the key elements and action scenes. Some minor tweaks are made for better animation and flow, but they don't change the core of the manga story.
The 'D Gray Man' anime and manga share a common foundation. However, the anime may adapt certain parts differently to fit the visual medium. It depends on how you view the adaptation, but both have their own charm.
