There's currently some inconsistency with the copyright and the qualifier for the characters. The character qualifier is mostly correct, though should be "saikou" and not "saiko". Not sure where "ten'i" is coming from, and am ambivalent on "suru" but looks like we tend to have it as a separate word in tags. Common practice with characters at this point is to use abbreviations for long titles, and "ansatsu kizoku" is the official one. It might be good to have an alias in place in case any are unaware of the abbreviation at first. Also putting in an alias for the official English title for those who forget or don't know the Japanese title.
