Mitsuhiro Tada (#4281)

Someone could check this artist aliases ?

Seems like he's also known with this name: "タダ ミツヒロ" (not actually in the database).

If it's right, could it be added?

Well, that's just his name spelled out in katakana, which is one of the phonetic alphabets. We probably don't need to add that as a variant unless he gets credited that way often, or commonly uses that instead of the kanji name.

After spending some time to re-check his credits, it's finally simple:

He's credited as "タダ ミツヒロ" for KOEI albums.
He's credited as "多田 光裕" for Konami albums.
