I am looking for a manga which I read a few years ago. I think an anime was also made. The setting is very similar to Strike the Blood and some characters also look similar. Their supernatural power/abilities come from an article of clothing or other items they wear or in procession of. One of the female leads had a swim suit that made her indestructible. I think their were also ribbons attached to it which helps her fight kind of like the ghost girl's ribbons in the new manga/anime Rewrite. I vaguely remember that bikini girl and the main character also had a subtle romantic relationship. It is a harem manga and the bikini girl is the only one I remember clearly. Please name anime manga/anime that pop at the top of your head somewhat similar to the description I provided. Rewrite is what reminded me of that manga/anime and trying to remember what it is. Vampire girl in Kore wa Zombie desu ka? might be closer to the appearance of the bikini girl.

Found it after a while of searching and searching. It was C³. Anime was also made of it and that bikini girl was Ueno Kirika.
