Comprehensive Manga: the Blood King Starting from Academy City

This is Academy City where superpowers and supernatural powers are regarded as "science". Here are not only the trio of monkey shoju Sakuranaha Shikame Maruka who have to conquer the Clow Card every day, the superpower Yuriko Misaka Mikoto who awakens superpowers through learning, the magical girls Homura Akami and Fite who hunt witches, Rukia Kuchiki who can't understand swastika, and even a half-baked vampire like Klein who doesn't have a girlfriend yet and is worried about too much homework assigned by Koro-sensei. But one day, a nun who claimed to have one hundred thousand magic books fell on the balcony of Klein's house. The flame-haired and scorching-eyed sword girl Shana and the paladin Artoria arrived one after another. In order to regain Index, they vowed to fight to the death with Klein, a half-hearted vampire. At the same time, Shinobu Oshino, who was making a big fuss at the Mao Spiritual Arts Academy, also came to the door. I'll fight you and I'll turn you all into vampires.
