Seasonal New Game+

Iroha's event is here (by 3rd time... while Shantotto's was only 2 times). New players can play this story, but those who already played it can't (besides FATEs and Unending Journey).

That is why I suggest this: include these special events in the New Game+ system, so we can play them again. However, these would be only seasonal as well. For example: Iroha's event can be in NG+ until June 22th (at event's end).

Obviously, this would be only for these special events (Iroha, FFXV...).
