I know a manga where the protagonist uses sword and shield Sicon of Light does, but it's been dropped or forgotten for ages, I believe, and half the chapters were jumbled up for some reason midway so you'll need to skip a few chapters as they're copies
Alternative name is Shen Yin Wang Zuo
Great story decent storyline, arts old but... it's still a good read
Just so you know if you go by the English spelling don't try to shortcut or accidentally misspell and even if you don't just know Child of Light is a different Manga about a kid with magic, not the same thing as Sicon but it usually shows up with Sicon due to name similarities.
