Comprehensive Manga: Starting with Summoning a Beautiful Girl's Familiar

Qingyu, who was summoned by Louise to the familiar world of Zero, was bound to the familiar summoning system, and the counter-contract made Louise his familiar. This world has been invaded by monsters. Qingyu had to use the system to summon a powerful familiar who happened to be a beautiful girl to fight against the monsters and liberate the world. At the same time, Qingyu can gain some of his familiar's abilities as his intimacy with his familiar increases. So why in the first level, the sky monster Tias and the ocean monster Steel Tooth Shark seem a bit familiar. It seems that the electric type has a special attack on the sky and water types, right? Then the orange-haired little girl summoned... "You sacrificed the entire Holy Knights and tens of thousands of troops but failed to cause effective damage to the monster. Are you taking this kid to kill him?" I don't know, but she fired the railgun and killed him in seconds. "The monster Rios who turned more than a hundred cities into a lava hell is unrivaled..." Luo Qixi: "It's probably worth 1% of the water saint level magician's trial." "The place of extreme cold is Aksia..." Megumin: "explosion" This novel and its characters are purely fictitious.
