This guide will cover:
1) How to download Dangan Pirates (KT entag game) on iTunes app store even when you're living outside Japan. (I don't use android, so I can't help you for that platform.)
2) Some basic things to look out for in order to get the KAT-TUN cards.

This entry is intended for players who have a minimum understanding of Japanese. The whole game is in Japanese, it's going to be challenging if you can't understand the language at all. I try as much to be specific but I'm sorry my real life won't allow me to answer many questions after this entry.

And many thanks to starry_glitter for all the game tips(^-^)/

( Aye, Pirates! )
