One Piece could be considered an anime with a very encompassing story. It has a vast world filled with diverse islands, cultures, and characters. The story follows Monkey D. Luffy and his crew on their journey to find the One Piece treasure. Along the way, they encounter various pirate crews, Marines, and other factions, and are involved in numerous political, historical, and personal storylines that span across the entire Grand Line and beyond.
One of the animes with a large amount of fanfiction is 'Harry Potter' (although it's not strictly anime but has a huge fanfiction following like many animes). However, if we are talking about pure anime, 'Naruto' probably has a very large amount of fanfiction. Fans have created countless stories based on the characters and the rich world of Naruto.
I can't answer this question because 'notebook' usually refers to the sex scenes in Japanese manga and anime rather than a specific anime. As a cultural phenomenon, the "book" was widely welcomed in Japan, but it also received some controversy and criticism. Therefore, different people might have different opinions on the question of which anime had the most scripts.
Rather than focusing on anime with sex scenes, I would recommend 'Cowboy Bebop'. It has a great story full of action, adventure, and complex characters. The plot is engaging as it follows the bounty - hunting crew of the Bebop spaceship. There are no sex scenes, but it's an anime that can really draw you in with its world - building and character development.
The anime with the most harem members could not answer because the harem type of work was not a mainstream type of anime and there was no clear upper limit to the number. Different works might have different harem settings and the works themselves might have different endings. Therefore, it was impossible to determine the number of harem members in an anime.
Another one could be 'Ghost in the Shell'. It's a classic anime with a thought - provoking story about the nature of humanity, consciousness, and technology. It has some mature undertones and scenes that are more on the serious and philosophical side rather than sexual. It's an anime that can make you think deeply about various concepts.
One such anime is 'Fullmetal Alchemist: Brotherhood'. It has a very deep and complex storyline that revolves around the concept of equivalent exchange in alchemy and the journey of two brothers to regain their bodies. It has great character development, moral dilemmas, and an overarching plot that is full of twists and turns.
One of the most popular manga-to-anime adaptations on Anime Planet is 'Attack on Titan'. It has gained a huge fan following due to its intense storyline and great animation.
I would say 'Clannad'. The love story between Tomoya and Nagisa is not just about their romantic relationship. It also involves the growth of their family, the challenges they face together, and how they support each other through difficult times. The story is full of heart - warming moments, like when they have their daughter and the family bonds are strengthened. It really shows the power of love in all its forms.
