Perhaps 'Attack on Titan' also fits to some extent. It has a post - apocalyptic world setting where humanity is on the verge of extinction due to Titans. The story is filled with a lot of twists, the exploration of human nature in extreme situations, and a constant battle for survival. Although it's not directly an 'errold story', there are aspects in it that can be associated with complex and dark story - telling.
One anime that might have some elements similar to what you mentioned could be 'Fullmetal Alchemist'. It has a complex and deep story with elements of mystery, moral dilemmas, and a unique world - building. However, it's not a typical 'errold story' but has some thought - provoking and darker aspects in its plot.
One common theme is often the exploration of moral ambiguity. In these types of stories, characters are often faced with difficult decisions where the line between right and wrong is not clear. For example, in 'Code Geass', the main character uses his power in ways that can be seen as both heroic and villainous depending on the perspective.
Another anime could be 'Attack on Titan'. In some intense battle scenes, characters can get caught in restraints or bindings as part of the life - or - death struggle against the Titans. It adds to the sense of danger and helplessness in the story.
Another one is 'Elfen Lied'. This anime has a very dark and tragic story. It's about a race of mutants called Diclonius, who are often persecuted. The main character, Lucy, has a brutal past filled with abuse and isolation. The story contains a lot of violence and gore, but also explores themes like discrimination, love, and the human capacity for both good and evil.
One anime that has some elements that could be related is 'Yuri on Ice'. While it's mainly a sports anime about figure skating, it has strong male - male relationships that are complex and could be explored in a BDSM - like context of power dynamics in a very mild way. But it's not a traditional BDSM - centric anime.
'Your Lie in April' is also a remarkable anime. It's about a piano prodigy, Kousei Arima, who lost his ability to hear the sound of his own piano playing after his mother's death. Then he meets Kaori Miyazono, a free - spirited violinist. Their relationship and his journey to rediscover his love for music form a beautiful and heart - wrenching story.
Well, 'Sao - Sword Art Online' has some elements of love story in it. Kirito and Asuna's relationship is quite famous among anime fans. They support each other through various challenges in the virtual world. Also, 'Fruits Basket' is a love - centric anime. Tohru Honda's interactions with the Sohma family members lead to some really touching love stories, both romantic and platonic. There's also 'Kimi ni Todoke' where the shy girl Sawako tries to find love and friendship.
Since I'm not sure exactly what 'bubble anime story' is, it's hard to recommend similar ones. But if it has something to do with a fantasy - like world, then 'Spirited Away' could be considered in a way. It has a very imaginative world full of strange creatures and situations.
There is also 'Fullmetal Alchemist: Brotherhood'. The two brothers in this anime, Edward and Alphonse, embark on a journey of self - improvement, facing numerous challenges and learning important life lessons, which can be seen as a great example of an 'anime meisei story'.
'Sailor Moon' can also be seen as an Anime Joi Story - like anime. Sailor Moon and her friends are on a continuous journey to protect the Earth from various threats. Along the way, they learn about themselves, their powers, and the importance of friendship. The series has a strong sense of progression and growth for the characters, which is characteristic of a 'joi' story.
In 'My Hero Academia', there are also characters with different body builds. Fat Gum is a hero with a large physique. His story is quite interesting as he uses his body fat in a unique way to fight villains. He also plays an important role in mentoring some of the younger heroes, adding depth to the overall story of the anime.
