I would like to know one thing about MISSIONS, when appears the character in a red square, I NEED to use him to complish the mission or not?

Becouse at TOGE mission I didn't use Yuzuki and yet I completed the mission.

no if a character is in a red square that means they are a mission character which is temporarily unlocked for that mission this doesnt necessarily mean you HAVE to use them unless the mission require you to do so.

You don't have to use them unless the mission says you need to win with them. If they're not required they're just their if you want to use them.

Edit: Ninja'd.

Yeah and you answered your own question... if you can do a mission without the mission charcter, you can complete the mission.

The mission characters just allows you to use the chatacter at that point in time.

Characters marked in squares are for the time being, unlocked. Doesn't always imply you have to use them, unless it says so in the mission description.

No, not unless in the mission requirments it says to.

They are there for you to use, but only for that mission.

yea so it optional to use that character if you want for that one mission, don't need to use him or her

you dont have to use if it is not in mission requirements
but you can of you want

yep, just some extra for a little while
