This is Shiro from No Game No Life anime. This is her bikini version paper craft.
Shiro is the main female protagonist of the No Game No Life series and the calm and calculative half of the siblings.
Abandoned by her parents, Shiro is an 11-year-old genius NEET (Not in Education, Employment, or Training) hikikomori (shut-in) gamer who, along with her step-brother, Sora, form 『 』(Blank). Sora’s dad married Shiro’s mother, both having remarried, thus making Shiro and Sora step-siblings.
Now, about the paper craft. I don’t know who design and build it. So there is no instruction in how to assemble but from looking on the template it looks similar to any figurine paper craft we had before.
If you’re used to building such figurine paper craft, anime paper craft then you should be okay.
