Well, soon enough, I'll enact my plan to get the cut girls in.
I've spent the past few months, since April in fact, saving up paid V-stones to reach enough paid V-stones to be able to do 20 rolls each for all of Leifang's gachas during her anniversary. I initially thought it was three gachas, but then I remembered it was four, so I had to do some huge grinding to make sure I got there by paying quite a fee to do so during Lobelia and Nanami's Jewel events. I'm now just barely at the minimum threshold of 400,000 paid V-stones. My secret was, besides obviously getting all the past monthly ticket packages starting the first full week of April up to now, also getting any packages that were deemed absolutely necessary. Also used quite a bit of them to get Leifang's Bouquet suit (that was more unplanned on my part since I was trying to get an S-rank in her final match to no avail, but at least I managed to contribute a little bit more than initially planned which will ultimately help in the long run).
The idea is that, since Team Ninja and Koei Tecmo are businesses, and per the rule of capitalism, they need to make profits befitting a greater demand, I'm going to roll all 20 (enough to get a free suit from the VIP shop) for each of the banners. I'll also post said results on their twitter page, and after doing all of that, inform them that it would be a very good idea given the profits they undoubtedly would have gotten from that bit, that they add in the likes of Tina, Mila, Rachel, Christie, and Lisa, even inform them that all that money I paid to get it up to that point was specificially dedicated to them appearing. Since Leifang was released on the DMM version on July 5, that means I'm going to do it on Independence Day at 11 AM. Let's hope Team Ninja and KT are going to be receptive towards it. I had to pay a HUGE sum of money the past thee months, which would be equivalent to a huge fortune for them (by my estimates, I had to pay at least $2304, meaning I paid them roughly 254566 yen, that's enough to purchase two seven-tier hina dolls at the barest minimum, so that's not exactly cheap by Japanese standards.). I intend to do whatever it takes to get TN to add the cut girls in.
I also intend to get 100,000 each for Fiona, Nagisa, Kanna, Monica, and Sayuri's anniversary gachas, though unlike Leifang, I hope to get them in less than 20 rolls, 21 rolls in Monica's case so she can get that bonus SR accessory for the second paid suit as well (and even there, I'm only aiming for their second paid suits, only because those suits come with a live change episode each. Well, okay, 2nd paid suit and accompanying SR accessory in Monica's case).
There are other reasons for why I'm trying to get 100,000 paid stones or more besides those girls, such as collaborations as well as the 1st and 2nd year suits, but those are definitely the primary reason.
