One key element is his birth in the Rukongai. Another is his strong reiatsu which led to his recruitment as a Soul Reaper. And of course, his Zanpakuto, Hyorinmaru, is a major part.
Well, Toshiro Hitsugaya comes from the Rukongai. As a young soul, he already had an air of leadership and strength about him. His journey began when he was scouted by the Soul Society to become a Soul Reaper. His training was intense as he had to not only learn to control his spiritual power but also understand his Zanpakuto, Hyorinmaru. This ice - type Zanpakuto was a reflection of his cold and focused personality. His origin story is also marked by his early experiences in the Soul Society, where he had to prove himself among the more established Soul Reapers.
A crucial moment in their love story is when Hitsugaya first realizes his feelings for Hinamori. It might be during a battle or a difficult situation where he sees her in a new light. Additionally, when Hinamori is recovering from an injury or emotional distress, and Hitsugaya stays with her, that shows the depth of their relationship. Moments where they have private conversations, no matter how brief, also contribute to their love story as they get to know each other on a deeper level.
One key moment is when they first have a deep conversation. Maybe it's about their pasts or their hopes for the future. This allows them to see each other on a more personal level. Another moment could be when Toshiro saves the reader from a powerful enemy. It shows his protectiveness and makes the reader realize how much he cares. Also, when they share a quiet moment, like watching the sunset in the Soul Society, it deepens their emotional connection.
Toshiro Hitsugaya and Momo Hinamori have a complex relationship. In the Bleach series, they have a deep bond that has elements of love. Hitsugaya has always been protective of Hinamori. He cares about her deeply, especially after she has faced many hardships. Their relationship is often one of unspoken feelings, with Hitsugaya showing his love through his actions, like always being there to protect her from danger.
Well, self - discovery is a significant theme. As he's still young, he has a lot to learn about himself and his place in the world. Fanfictions might take him on a journey where he uncovers parts of his past or future potential. Another common aspect is his role as a leader. He has to lead his division, and fanfictions could show the challenges and triumphs he experiences in that leadership role, all while dealing with the various threats that come his way in the Bleach universe.
One common theme is his sense of duty. Since he is a Soul Reaper, many fanfics explore how seriously he takes his responsibilities.
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.
One common theme is the contrast between his cold and stoic nature and the warmth of love. Writers often explore how his initially icy demeanor changes as he experiences love. Another theme is loyalty. His loyalty to his comrades in the original series is sometimes translated into loyalty towards his love interest in fanfiction.
A good Toshiro Hitsugaya crossover fanfic should first have a believable crossover concept. For example, if he crosses into a different anime world, the rules of that world need to be well - established and his integration into it should make sense. His character traits should also be maintained, like his cool - headedness and strong sense of justice.
One common theme is the exploration of new powers. When Toshiro Hitsugaya is in a different universe, he has to either adapt his existing ice - based powers or gain new ones. For example, in a crossover with a superhero universe, he might learn how to fly or have enhanced strength.
