Although the developers haven't confirmed Swimsuit Ciel, players were greeted players at the event sign-in reward screen alongside Swimsuit iCO. She's also featured in the event stage main screen and has her own card (more on that later).
This is pretty much what Capcom Taiwan did with SD Zero. It was a total surprise to players, followed up by an official confirmation a short time later.
Now, as opposed to previous summer events, this year's themed stage has no boss and no story. What's more, it's unlikely we'll see a third summer-themed character. It remains to be seen if the traditional daily free 10-pulls will be skipped too.
Next, via the official Japanese Twitter account, we can take a look at Swimsuit iCO design sheet. Credit to Windii for the translation!
And that's all for now. Keep you eyes peeled to Capcom Taiwan social media for Swimsuit Ciel trailer on Monday!
