(First, I'm not goot at speaking english)

You can hire all of them (20 characters).

Some of heroes will appear when you meet the number of rebirth requirements

Therefore, I recommend you rebirth at least 5 times (at the second world or icy world) before you try to finish the end

I think the best efficient investment of rebirth points is drop (> money > exp)

If you complete hiring all of characters and items, you will reset the rebirth points and invest the exp.
