A crappy, Mary Sue, Naruto OC created by UchihaPuchiha on DeviantArt. She looks exactly like Sakura and Tsunade fused together, except with light strawberry-blonde hair. Apparently, Sasuke is so in love with her that he acts OOC and protects her from everything. Sawaii also happens to have an abusive love-interest named Ren. He almost killed her in the Chuunin Test fights, but he still chases after her anyways.
UchihaPuchiha just edits pictures of Sakura or SasuSaku fanart to "draw" Sawaii. What little pictures she claims to have drawn herself are usually traced. (example: A picture of Sasuke carrying his and Sawaii's demon offspring was traced from a picture of Ichigo Kurosaki carrying Nel.)
Sawaii's name most likely comes from the word "kawaii" combined with "Sakura." (Or the creator just made it up on the spot. Either way it's Wapanese.)
UchihaPuchiha always titles her deviations with Wapanese words like: "Ohayo, minna! Minna, genki? Nani?! Baka-chan! Sugoi-desu, ne???" You can't understand any of the things she says, which just makes you want to punch her in the face more.
She has an entire Weeaboo army behind her, so beware...
Sawaii Hitomi: OMG, LIEK, SASUKE-KUUUNNNN!!!111 LETZ GO RUN AWAY FROM MAI ABUSIVE LUV INTEREST REN!!!!11
Sasuke: WTF. Somebody get this frickin' weeaboo away from me...
Karin: Challenge accepted.
