Little is known about this unicorned-masked person. 

 

In Ancient Languages, "Kurupuru" meant "the cute one" or "the sweet one" - usually in relation to cute short girls - not to be confused with an ancient game "Kuru Kuru Kururin". Some library arcades had it defined as a brain disease.

 

The mysterious nature of this unicorn-masked person becomes even more evident when Kurupuru seems to be what Serioja has been looking for, what Liu Junjie needs in order to solve the glitch in his Supertask, what Lavinia has to capture in order to complete the mission given to her by Madam, and finally what Berbek desperately needs to bring to Ecaterina. But why is Kurupuru so essential to all these people's lives? And most importantly, what is Kurupuru ?
