This time around, it's going to be appearing in the G123 platform (?), and apparently you can pre-register in 3 ways: by following the QBLB twitter above, friending them on Line, or registering in the actual site (you only have to click on the blue button and enter your email on this last one, and you get a code for extra rewards in your mail?). Right now they're trying to reach 50k preregistrations by the end of the month, to get us a lot of rewards, so just in case, every effort you guys make will help.
What's it going to be about tho? Apparently Elina gets swallowed into another world in the middle of QB, and she and Airi set out on a journey to find Leina.
And about the gameplay? Apparently the girls will battle on their own, with the key to victory residing on their positioning, a "simple but deep strategic game". Also, you'll be able to raise their affection with items obtained through battle to unlock "(fan)service illustrations".
They also tease a kind of Mirim in one of the pics, so it's unknown if there's going to be some Rebellion involved.
More news as we find out!
Hype!!
