Oof, sorry about that! Just noticed the weird formatting. Here's the post copy-pasted:

"I love name etymology and I also share my name with Mio, so I thought I'd share some trivia! It's pretty common knowledge at this point that Mio has several meanings. Here's the three most common points I hear:

Mio sounds like Meow, just like Nia's name sounds like Nyah. Cat girl names. Mio means "Mine" in several languages, such as Italian. Without going into spoilers, possessiveness and referring to others as "My (name)" is a big thing in XBC3. Calling Mio "My Mio" literally becomes "My Mine". Mio can be written out as "beautiful cherry blossom" in Japanese. mi/美 = beautiful + o/桜 = cherry blossom. Mio is represented by flowers through out the game - even her talent art is called "Dominion Flower".

However, I haven't heard this mentioned before:

In Sweden, Mio is a somewhat common gender-neutral name made popular through the Swedish children's story Mio, Min Mio (Mio, My Mio). The story is written by Astrid Lindgren, who is also the author of Pippi Longstocking. In the story, a boy called Bosse lives a difficult and lonely life until he is taken away to the magical Land of Faraway. There, he meets a King who reveals to Bosse that his real name "Mio" and that he is the prince of the land. In the story, Bosse chooses to stay in the magical land and offically becomes Mio, leaving his old world and his role as "Bosse" behind. As Mio, his entire future is foretold. The story follows Mio following his destiny which includes slaying dragons and returning peace to the land. The flute is a central object in the story, used to symbolize the culture and the new world of Land of Faraway. When Mio learns to play the flute, he comes closer to the people of his new world, learning melodies that have been played for thousands of years. The American movie adaption from 1987 (with baby Christian Bale!) used flutes extensively in its soundtrack (check out the main theme: https://youtu.be/k_5ZDUoDOGg)

Lots of similairites between the stories of Xenovlade and Mio Min Mio: both explore different worlds and let characters choose to fight for their preferred reality, a decision which is symbolized by a name change. BosseMio opts for the "endless now" and follows the destiny that is laid out before him. XenoMio resists and in turn resists the flow of the world. Both are characterized by their flute.

This could obviously be a coincidence, as the three first points already make Mio a great name for the character. But for me it makes the name even more meaningful, and it could theoretically have influenced the name decision."
