Sharing stories with such improper content is against good moral and ethical standards. Instead, we could talk about sisters' strong bond in the face of difficulties or their shared hobbies.
Sure. There was a little sister who was really into art. She had this 'tight ass' attitude when it came to her paintings. She would spend days perfecting one piece, carefully choosing the colors and brush strokes. Her dedication paid off when she won an award at a local art show.
There's no way to know for sure who Harry is just from this title. He could be an original character created for the fanfic, or he could be a character borrowed from another work and being used in a new way within this fan - created story.
I'm not sure specifically as it's an odd title. It could potentially be about a character named Harry who is making changes or having an impact on a fan - created story related to something described as 'tight ass'. But without more context, it's really hard to say.
One positive story could be about a mom who started her own small business from scratch while also taking care of her kids. She had to juggle between meetings, product development, and taking her children to school and extracurricular activities. But through her hard work and determination, she not only made her business successful but also taught her kids about perseverance.
One story could be about a little sister who was very determined in a sports competition. Just like her 'tight ass' in the sense of being firmly committed, she trained hard every day and never gave up. When the competition day came, she overcame all the difficulties and finally won the championship.
Well, it could imply that in a Naruto - related fan - created story (fanfic), Naruto somehow causes destruction within a situation that is very difficult or 'tight' in the context of the fanfic's plot. But without more context, it's really hard to be specific.
It's a rather odd statement. 'Harry' here might refer to a character named Harry in a particular fandom. 'Ruins' implies that he somehow spoils or negatively impacts a 'fanfic' (fan fiction). However, 'tight ass' is an inappropriate and unclear part in this context. It could be a very unorthodox or poorly worded description within the fan - created story.
It could mean that Harry, whoever he is in this context, takes actions that undermine or break apart the 'fanfic'. Maybe he's a character within the story of the fanfic and does something that goes against the plot or the intended message. The 'tight ass' part is a bit unclear, but it might be a creative or colloquial way of characterizing the fanfic as being too rigid or something similar.
