Back from Otakuthon

Ok, so I'm not actually back - I slept in my own bed on Saturday night since I live within driving distance - but still, Otakuthon is over, and I am a little sad. Exhausted, happy about my week-end, but a little melancholic.
Anyways, I'm already full of ideas for next year, and I have something to announce, but that will have to wait. For tonight, I will present pictures from my week-end (mostly taken by me). Since I don't know most of the cosplayers and cosplays, I will invite you to play "Name that Person / Character". I'll name the ones I know, you help me with the rest. Lets Begin...
1) Gwenyver and Daughter as Rosalina and Toadette.
See, it's easy!
2) Marie-Ange-the-Celt and Gwenyver as Tifa Lockhart and Aerith Gainsborough.
3) Marie-Ange-the-Celt as Aruhaniel the Drow. This is her LARP persona in Asian style clothing. Photo not by me.
4) Mageknightterra, Technobug, Tioniel and 2 cosplayers I barely know yet (forgot their names, girls help please!) and the 5 Sailor Scouts, Sailor Mercury, Sailor Venus, Sailor Moon, Sailor Jupiter and Sailor Mars.
5) Another Cosplayer I was briefly introduced to and forgot their name and Luke as a Jawa and another character from Star wars (I shouldn't be doing this when I am this tired - my brain is mush!)
6) Oh darn, she gave me her nickname and I can't remember. It had to do with Mischivious or something. Oh well, I'll find it and let you know. Obviously, she is dressed as a Geisha in an actual Kimono.
7) Dante from Devil May Cry (thank you to Ethan Kincaid for the information). Cosplayer unknown.
8) Cosplayer and Cosplay unknown. But cool wings!
9) Oh I know this one, it's from Spirited Away (2001)! It scared my daughter sillly. She still talks about the monster. Cosplayer unknown.
10) Cosplayer and Cosplay unknown. Love the mask.
11) I actually asked this girl what series her costume was from and she said none, she just choose to wear this saree which she had. Well it is lovely! Cosplayer unknown.
12) Armurita as Ashura from Tsubasa Reservoir Chronicles (Thank you Armurita for letting me know). Incredible headpiece!
13) A group photo of characters from Bleach (Thank you to TheYellowRose for that information). Cosplayers unknown.
14) I know this guy won something in the Masquerade. Wait, let me check the winner's list... Darn, no name, just the entry "Did you know surfing". So Cosplayer and Cosplay unknown.
15) Cosplayer and Cosplay unknown. I think she is just a regular Lolita, but I liked how she looked.
16) Cosplayers and Cosplay unknown.
17) Loki as... Cosplay unknown. 18) Cosplayer and Cosplay unknown. Awesome workmanship though!
Ok, now it is your turn to help me fill in the blanks!
