Yep I assume using the paid currency is exactly what he did. Capitalist gives you enough green bucks to max approximately one BP fully and half of another. If you throw around $250 at Helius, you can max them all, what a deal. It still probably does not give you enough gacha rolls to unlock all animations, even if there is only 40 per girl now ; if I remember correctly, 0.4.9 had more per girl than 40, also for whatever reason the removed anims were (imo) the better looking ones.
