Another plot could be that Ichigo's vampirism gives him unique powers that he has to learn to master. But these powers come with a price. For example, he might need to consume blood regularly, and he has moral dilemmas about where to get it. His friends might suspect something is wrong with him, and he has to figure out how to keep them in the dark while still being a part of their lives.
Perhaps Ichigo, as a vampire, discovers a hidden vampire society with its own rules and hierarchies. He has to navigate this new world while also dealing with his old enemies who now see him as a different kind of threat. He could also form alliances with other vampires who share his values.
One idea could be Ichigo struggling to control his new vampire instincts while still trying to protect his friends. He might have to hide his vampiric nature from his family, which adds a layer of secrecy and tension.
One idea could be that Ichigo has to hide his vampire nature from his friends at first. He struggles with the new instincts and powers, like enhanced speed and strength. Maybe he has to resist the urge to drink blood from his loved ones.
Well, a plot could involve Ichigo being turned into a vampire against his will. He then has to deal with the internal conflict of his human morals versus his new vampiric instincts. He might find that some of his friends are scared of him, while others are determined to help him find a way to reverse the transformation. And there could be a love interest who accepts him despite his new nature, adding a romantic sub - plot to the story.
Perhaps there's a world where vampires and Soul Reapers co - exist, and Ichigo and Orihime get caught in the middle of a power struggle between the two groups. Orihime's powers might be the key to peace, and Ichigo is determined to protect her.
Maybe fem Ichigo has a different set of powers compared to Ichigo. In the fanfiction, they could train together to combine their powers in a unique way. For example, her powers might be more focused on defense while Ichigo's are on offense, and they learn to complement each other. This could lead to some interesting character development as they overcome their differences and work towards a common goal.
One idea could be Ichigo having to face new and more powerful enemies in his resurrected form. Maybe he discovers new powers that come with this resurrection and has to learn to control them quickly to save his friends.

One idea could be Ichigo being transported to a different anime world where he meets a harem of characters from that world. For example, if he ended up in the Naruto world, he could encounter female ninja who are intrigued by his unique powers and personality. Another plot could involve a magical spell that accidentally creates a harem situation for Ichigo in his own Bleach world, with various female characters suddenly having strong feelings for him. Maybe there's a time - travel element where Ichigo goes back in time and gathers a harem of historical figures with spiritual powers.
One idea could be that Ichigo arrives in the Fairy Tail world and his powerful spiritual energy is mistaken for a new type of magic. He could join forces with Natsu and the gang to fight against a common enemy that threatens both his world and the Fairy Tail world. Another could be that Ichigo's zanpakuto has some sort of unique interaction with the Fairy Tail magic, like being able to absorb or nullify certain spells.
Maybe in this other world, Ichigo discovers a group of people who are similar to the Soul Reapers but have different powers and a unique hierarchy. He could get involved in their internal conflicts and help bring peace while also trying to find a way back to his own world.
