Wow, kinda surprised DMM has so much activities in past 2-3 pages. Well that's a given since compare the 2 version, Nutaku is clearly a money hunger who never five a freebies no matter what occasion it is.
I went for step up deal when I started the game, and I think it's yen. Since it slightly cheaper than 500 NG in Nutaku. Once my part time pay come in, I may go for 5000 deal to support the game though.
