It's the season for love, so of course that's made it's way to Venus Island for the ladies from Dead or Alive Xtreme Venus Vacation. The latest event is the Melty Venus Valentine ～Sweet Room Chapter～.
As a login bonus, you will get up to 15 Chocolate of Memories, along with some upgrade stones. Giving this chocolate to your unlocked characters will get you some "amazing rewards".
There are two new swimsuits for this event; the Melty Heart and the Thank You, as well as the Purity Bow head accessory. Wearing this stuff during festivals will increase your stats, and give you bonuses. There is also some limited time furniture, including a heart-shaped sofa and a "chocolate bed", which has a chocolate bar headboard.
If you want to participate in these festivals, unfortunately Dead or Alive Xtreme Venus Vacation is still only available in certain regions via Steam, and digital download in Japan.
