Hello everyone, may I ask for your assistance in looking for a specific manga?

Sadly, I don't recall the manga title, nor specific names in it... >.>

But I do remember that it has a swords and magic setting. The main characters are a young king (or prince that is ruling his country), his younger sister who wields a destructive magical power equivalent to a nuke, and their male childhood friend who is a master of the sword and leader of their personal guards.

It's been a while since I last read this manga, and I think it may even still be ongoing. I think the older brother in the story is also sickly and keeps on enthusiastically pushing for the childhood friend to marry his younger sister. It also seemed that the childhood friend/ master swordsman is the main character of the story.


Any help finding out what manga title this is would be much appreciated. Thanks!

It's GodSeeker
