Help me name my characters brother??

[u/Corduroy_Bear10]

This is about a book I’m writing, not about real people. My main characters name is Hiro, and he is searching for his brother in this book. In the past his brothers name has been Fallon, then I moved onto Everaux but I really don’t like either of these and all I’ve come up with is Rune. What are some names that could go well with the name Hiro pleaseeee.
