I don't make a more elaborate translation because my english/japanese levels would make it way too slow as there are words I don't know in one language or the other, but you should get a good idea of what that was about.
A) It's bout the "Calling Faith (Trust) in a party" from the other day.
They say that while in the future they want to make it possible for anyone in the party to call Trusts in the June version update only the leader will be able to call them while in a party.
(The 6 member limit for the party will still apply)
They are working on allowing anyone to call Trust, but it is restricted to the party leader for now because they found a problem with the system, and they would like to see how things go with this first.
The party leader will be able to call Trusts 120 seconds after they last invited someone into the party.
B) It's about some questions they received.
Q: How it will work if the party leader leaves and Trusts are out.
A: After a new party leader is selected the new leader can call Trusts back.
Q: About the new leader being able to call Trusts if there is a leader change.
A: Yes, the new leader will be able to call Trusts right away.
Q: About when or what will make Trusts will disappear
A: First if you are invited to a party and there are Trusts already out they will return.
In addition Trusts will return after a change has occurred in the party, like disbanding party, kicking a member out or Level Syncing.
And finally because of this it is recommended to first invite all the players and then fill the empty spots with Trusts. In order to ensure the party will run smoothly. (Also known as use your common sense dummy =P )

And that's about it.
