[TOMT] Anime with side character who controls stone henges

Hi all! I’m trying to locate an anime I watched last year and am just having no luck. Unfortunately I’ve had some memory issues and all I can be sure of that is from this anime is a female side character from Scotland who’s power is the control of multiple stone henges that she can use to heal/shield/fly on/etc. At one point she takes too much damage from a fight (I think maybe during a fight over the ocean, she was partnered with an American an hero) and wraps herself in the henges and flies herself to Australia where another character is able to heal her. I think there was some type of monster association that was setup as the villain group. I’ve tried quite a few permutations in google with no luck. Any help is greatly appreciated!
