Well, the stages above the 50th floor are technically optional (well, they all are, but the 50 first ones are the ones you) and the prize the players who get to complete the 100th floor is definitely some kind of special bonus. With swords only up to lvl. 56, you should be able to get Hakata on the 50th floor, and that's the main objective of the event (not to mention he will be useful in future events). I think it was nice of them to make easy enough for new players to get Hakata, but also challenging enough that older players will want to keep forward, if they choose to do so.

But answering your question, someone below said it ends on July 7th.
