It is not faith, so what's the reason behind why you guys can't re-release this beautiful set? I tried searching it on this website http://rose.kuro-tejina.com/ and I found out that it was also obtainable through Full moon gift chest and Full moon gift chest (Special).
Its item grade type is event so please re-release that event and reward at the same time so any player, whether new or old can obtain and own the said set again. This is a good way for players who like that set but can't afford to buy due to its current market price which is NOT reasonable given the fact that it's not a faith and can re-release again.
Thank you
