Time Travel in Attack on Titan

I hope the author's heroine is Christa. Remote: Control a brainless giant, you can add more, but not more, otherwise you won't grab the coordinates, and then you can't compete with the royal family for control. You can control it exactly like you control the intelligent giant, but the body cannot move, like the Warhammer Giant, and cannot transform again within a day. The body is weak. If you control multiple giants, you will be twice as weak Combat: The body is 18 meters Giant, with thick flesh all over the body, and armor like armor (much weaker than the armored giant), melee birth color, but not sensitive, and consumes a lot Combat: The body is 18 meters tall, with thick flesh all over, and armor like armor (much weaker than the armored giant), excellent in close combat, born with sensitivity, huge consumption, and can't see things, can only listen with ears, and becomes weak for 1 day after returning to human form
