(My eyes are going funny so I'm going to stop for now at this point. I started this in the duplicate persons thread but not only is it getting rather complicated I'm still not sure if this is multiple people or just a lot of typos)

Mayu SAITO

I'm suspecting something is up here since there's credits from both the sakuga and shiage departments and an error flagged for the name. Either there are two people, or they get misspelt a lot. This will take a while so I'll save my progress a few times in case something goes awry (PC crashing, browser crashing, accidentally closing the wrong tab etc.)

So, source checking the colourist roles:
Samurai Champloo: 斎藤麻由 (仕上 eps 3, 8 - source) / 斉藤真由 (デジタルペイント ep 20 - source)
ToHeart RMM: 斉藤麻由 (source)
GUNxSWORD: (provided sources are invalid and I cannot find an alternative - believe me I've looked)
Ergo Proxy: (having problems locating a source again.. have episode 8 on retail DVD.. only has English credits which have "Mayu Saito" as a "Paint Check Assistant". OK, I had a look through my old archives and found some raw episodes on a DVD-R and it still reads.. low res divx and the artsy angle make it difficult, but looks like 斉藤真由)
Gintama: 斎藤真由 (source)
Iroha: 斉藤麻由 (source)
Code Geass R2: 斎藤麻由 (source)
Votoms Pailsen Files: 斎藤麻由 (source)

And the animator roles:

Iriya no Sora, UFO no Natsu - 斉藤真由 (source)
Eyeshield 21: 齋藤真由 (source)

Going to skip double checking the credits with alternate sources for the moment and start some analysis:

斎藤麻由 and 斉藤麻由 only appear as colourists

齋藤真由 and 齋藤麻由 only appear animators

斉藤真由 and 斎藤真由 appear as both

Have I mentioned how annoying it is when someone submits a credit for a minor staff position with a source link of the front page of the series official site (not even the staff page)?

--edit--
They've appeared twice in Kiddy GiRL-and now, under two different names and two different roles - added to the list.
