Personally, the person I find most like myself was Emiya Shirou of FSN. Just, alot less oblivious to my surroundings lol. But the mindset is the same. I guess im too serious about stuff to often :\
Kurogane from Tsubasa reservoir chronicles... only because i get angry really easily. I'm not really that strong :cry:
I could also be like kimihiro watanuki from XXXHolic.
See here:
"Watanuki is known for a having both a volatile and caring nature to him. Depending upon the person he talks to, his emotions tend to be overly exaggerated. With Himawari he throws himself into the air accompanied by hearts and a "Himawari-chaaaaan!!" squeal. With Domeki, he almost always expresses irritation with various facial expressions, screaming, and arm motions that reminds Himawari of an angry cat. With the exception of these two and YÅ«ko, Watanuki tends to address everyone around him with formality and kindness."
