The pilot of the Provisional Evangelion Unit-05, very little is known about Mari, and her designation amongst the other Children has yet to be revealed. She has poor eyesight and is shown to have a difficult time locating her glasses when she dropped them from the collision with Ikari Shinji while parachuting. She also seems to have a fetish for LCL, as she appreciates Shiji's "smell of LCL".
Megane Complex sent this in and tells me this is another photo from Winter Comiket 2009 that I have yet to feature. Honestly, I wouldn't even know which anime she's from if it wasn't for the contributor. Thanks again for the email!
