I noticed that the tag "Syrinoth" is deferring to "Hiroi Kairu", which is an alias he only used for a few years and is not his actual name (he is not Japanese). As "Syrinoth" is his active alias in the fandom it seems to me that it would be more appropriate.

I've tried correcting the tagging manually on his images, but the alias set is overriding the attempted correction.

ok, hiroi_kairu -> syrinoth alias added.
