There could be. Try looking at dedicated anime fanfic communities. Often, these communities have rules against adult content, so the fanfics you find there are more likely to be suitable. They might have stories where Shizuka is portrayed in a heroic or interesting non - sexual way, perhaps her using her medical skills to help the group in different situations.
A possible fanfic could involve the OC being a scientist who teams up with Shizuka. They might be working on a cure for the zombie virus. Their relationship could develop as they face various challenges and close calls with the undead. This would bring out different sides of both characters.
One idea could be a fanfic where Shizuka uses her medical knowledge to create a makeshift hospital in the post - apocalyptic world. This could show her as a strong and resourceful character, and how she interacts with other survivors who come to her for help.
First, you need to develop your OC well. Give them a backstory, personality traits, and goals. For example, if your OC is a former athlete, that could influence how they handle the zombie apocalypse. Then, think about how they would interact with Shizuka. What would be their first meeting like? A tense encounter or a more friendly one?
One possible storyline could be that the OC is a new student who quickly befriends Shizuka. They end up having to rely on each other during the zombie apocalypse. For example, the OC might have some unique survival skills like being able to find hidden shelters, and Shizuka uses her medical knowledge to keep them healthy. Together, they form a strong bond and help other survivors as well.
The OC can be given special physical abilities. For example, being extremely fast or having great strength. This would help in situations like escaping from zombies or fighting off attackers. In the story, the OC could use these abilities to save Shizuka from dangerous situations, showing his or her strength.
