desu wa is a verbal style(?) that certain characters in Japanese media use when speaking. I have no idea how prevalent it may be in actual spoken Japanese outside of fiction. They tend to end their sentences with desu wa a lot. I am not a native speaker, but my understanding is that formal speech often ends sentences with desu (usually just shortened to des when speaking). Then, the wa part at the end basically adds some feminine flavor to the sentence (the male version is yo). That is why you only see female characters that are desu wa characters. Also, they tend to be more like an ojou-sama type character that is somewhat prim and proper, like our MC in this story.
If you are anything like me, now that you know about this, it will be impossible not to notice it when you watch anime now. They are somewhat common and the desu wa ending is really easy to pick out when listening, even if you don’t understand the language. A personal favorite desu wa character of mine is Mio from Tsukimichi if you want a concrete example to check out.
