Your Warmth - Reina

Sera and Reiyu's daughter Reina, whom I'm pretty sure is now canon with this design thing. Significantly less cheerful or outgoing then her brother or dad, Reina carries a sternness about her that reminds her mother eerily of Lyevorleredi, although thankfully she's not as insufferable or racist.

She is, however, not one to put up with foolishness, and would rather pursue quieter hobbies, and walks in peaceful forests, and such.

That being said, she's still the daughter of a spellblade and a hero of legend, and her skill with the sword isn't too far behind her brother's once she hits adulthood.

Until then, go away, she's reading.
