When will Garo event end?

[Gunspec]

Its been implied that the armor will be available for purchase until 4.0.

Which is why I find it weird that they never announced the event will be winding up soon. They gave an announcement several weeks before Yokai Watch ended which confirmed the ending date. No word on Garo, and the most recent thread I could find on google discussing an end date was back in March. I can't believe they'd just kill a collaboration without warning. Especially because this collab was to celebrate the lead artist from Garo helping to design armors in Stormblood.
