Why is my Naraku not a Mary-Sue

Yes, I'm still at it. Mary-Sue's are characters that are so perfect they get boring. And Naraku is perfect. Still, she has many, many flaws and therefor she is not a Mary-Sue. I have decided.

Her flaws:

• She had to grow from 0 to now, mentally.
• She has trouble understanding figure of speeches, but is finally getting there (after 8 years!)
• She repeats expressions because she thinks it's an expected response, despite not knowing it's meaning
• She can do anything... but she is so balanced she excells at nothing. (This is partly a reference to myself. I can write, draw, sing, code... but there's nothing I'm REALLY good at). She can fight well, but is exceeded by her teachers, who specialise in 1 weapon/skill
• She has the attention span of a potato (meaning no attention span whatsoever)
• She doesn't think before she acts
• She gets depressed easily
• She can't die (for numerous reasons, not only because of her awesome powers, but that would be a spoiler)
• She is hated by 1 person, again for reasons I cannot say (book 4 revelation stuff)

I could probably think of more, but I had to convince myself my Naraku is not a Mary-Sue. Not even Konoai is one, because she has superiority and inferiority issues at the same time.
