   Summary

   Cross and Epic are the most legendary thieves in the whole world! But there is just one teeny tiny problem…that is actually…not…true, heh.

   But it is okay! All they need is an opportunity to show the world what they are capable of!

   And an opportunity is exactly what they got, all they need to do is invade a rich guy's mansion and steal an artifact that only existed in legends.

   What could possibly go wrong!?

   (Answer: a lot.)

   Or, follow Cross, Epic, and a very questionable new addition as they try to build a name for themselves without getting caught, killed, or completely derailing their own plan.
