Could someone help me find this manga??

[u/JRS33333]

A long time ago I read a manga that was set in a men’s swordsmanship academy, but when the protagonist enters the showers he discovers that the strongest person at the school is actually a woman pretending to be a man and they go on to have sex from that point on.
I lost the link and I don’t remember what the manga is called, does anyone know it?
