A common theme is friendship evolving into something more. Their initial respect for each other as comrades in Soul Society often develops into deeper emotional bonds in fanfictions.
One popular 'hitsugaya and rukia fanfiction' is 'A Bond Beyond Duty'. It delves into their relationship as they face a new and powerful enemy in Soul Society. The story beautifully captures their unique personalities and how they support each other during tough times.
There might be some. You can start by looking on fanfiction platforms like FanFiction.net or Archive of Our Own. Search for stories that are rated as 'General Audiences' or 'Teen' to avoid inappropriate content. Some authors might write about the idea of Hitsugaya and Rukia starting a family in a very innocent and platonic way.
You can find some really good ones that explore their backstories. Maybe a fanfiction that delves into how Hitsugaya became a captain and Rukia's early days in the Soul Reaper academy. These stories often show their growth and development, and how they became the characters we know, without any sexual implications related to pregnancy.
There's a fanfiction called 'Toshiro's Journey of Redemption'. It takes Toshiro on an emotional journey where he has to face his past mistakes. The author does a wonderful job of portraying his internal struggles.
If we think about rukia, she is a character with a complex past and a strong sense of duty. Renji, her long - time friend and ally, has his own journey of growth. In rukia renji fanfictions, they might be shown as having a connection that goes beyond the ordinary, with rukia's cool exterior melting in front of renji, and renji being able to be more vulnerable around rukia. This can be explored in various non - adult ways in fanfiction.
Naruto would probably be very curious about Rukia. He'd ask her a lot of questions about where she's from and what her powers are. Rukia, on the other hand, might be a bit guarded at first but would gradually warm up to Naruto's friendly nature.
One possible plot could be that rukia and byakuya accidentally end up taking care of a baby. They initially struggle as they are not used to this situation. Byakuya with his strict nature tries to impose order while rukia is more lenient. As they care for the baby together, they start to understand each other on a deeper level and their relationship grows stronger.
I'm not entirely sure if there is a large quantity of it, but considering the popularity of both Harry Potter and Bleach, it's very possible. Some fans enjoy creating scenarios where characters from different stories interact. For example, they might write about how Toshiro Hitsugaya would fare in the wizarding world of Harry Potter, or how Harry Potter characters would react to Toshiro's ice - based powers. However, you would need to search on specific fanfiction websites to find such works.
Another option is to follow some well - known fanfiction writers in the Bleach fandom (since Hitsugaya is from Bleach). They might have written something about Hitsugaya and Karin. You can find these writers on the aforementioned fanfiction platforms or by following Bleach - related fan groups on social media.
