Squared Bunny's Manga

Reborn girl in a fantasy world with the memories of this world hears the rumours of a 'saint' that sounds like she may be from this world as well. This leads to the fox hunting a snake in order to save a duke.
Setup much like 'The Stereotypical Life of a Reincarnated Lady', but without the filler and slow story advancement, and the 'saint' has a different agenda in this story.
Tbh. the first chapters (10 or so) made me fear a teen written story that would be over the top and cringy, but it is surprisingly well put together and executed. Not overstaying its welcome.
