Nvm this.. i didn't read the forum messages right, i thought my thread wasn't posted. >.<
No idea what Fujiwara is talking about Otakool, Malmoth and Perle are well above the 600 credits you have. Go to the market, choose Junkz and sort by price. You'll be able to see what Junkz cards you can afford.
You didn't understand my friend, 600 credits, not clintz.
