What is carved into Toko's leg? DanganRonpa: Ultra Despair Girls came out today in Europe and there's something I noticed about the 3D model of Toko Fukawa.

There's something cut into her leg. I'm not sure that picture is an official model from the game, but I have definitely seen it while playing (screenshot below):



In the other games, we mostly see her waist-up - or in an uncut skirt, so I've never noticed it before:



What has she got carved into her leg?

I've only been playing the games - is there another source that describes how it got there?
The mark seen on Genocider Syo is the Japanese Kanji 正

Wiktionary has a page on this character explaining its use as a tally mark by the Japanese. 

Genocider Syo uses the tally to count the amount of victims she has killed. There is also a small section on this on the Wikia. 

Since each one represents 5 kills, you can see she has killed quite a few!
