Villainess Level 99: I May Be the Hidden Boss but I'm Not the Demon Lord Act 5 (Light Novel) by Satori Tanabata

As the arrival of winter brings the date of Yumiella and Patrick’s wedding ever closer, Yumiella ends up being tricked into visiting the Royal Capital in order to prepare for the big day. While accompanying Yumiella, Eleanora visits a friend from the Royal Academy and discovers that her family is on the verge of being run out of the city due to court politics. As much as Yumiella hates getting involved in these sorts of machinations—especially when they concern politics—how could she say no to her dearest friend Eleanora when she asks for help?

Though Yumiella, now well past level 99, can usually use her strength to deal with most problems, it turns out that the minister of finance is pulling all the strings behind the scenes, and he’s taken Yumiella’s interference into account as part of his plans. She might not be able to brute force her way out of this one, but Yumiella’s not one to back down from a fight, especially when it’s for Eleanora’s sake!
