A manga with a armor made by diamond... Help ?

[Tcof]

Anyone know this manga ?
Action fantasy kind, no scientific
It is like a super saiyan moment so i don't know the armor around a lot.

CYaZALEA Kiss?

@dabson no, i don't think so. It is like super saiyan, so it is one of a kind armor at the moment. No one else have it. ANd it not gold like Saint seiya?
@421cookies No, the one wearing it is male, probably that the protagonist. can't remember a lot,
I read it by a local hard copy, which mean it probably old, i guess it older than Naruto
