I Only Summon Amazon Giantesses

In a world where Summoners command dragons, demons, spirits, and mythical beasts, the strongest people are those who possess powerful summoning abilities. When Mark, a 16-year-old late bloomer, awakens his power, everyone expects him to summon a traditional creature, or to remain as a mundane. Instead, he summons a beautiful giantess warrior, with a ranged and measured height of 20.7ft tall, weight of 1300lb, waist and hips width of 166cm, 226cm, respectively. He is immediately mocked as a joke, judged and casted as an anomaly, but the giantess isn't human. She is an Amazon—a member of an ancient and legendary race of giant warriors believed to have a strong and strange history. And she is only the first. As the Mark grows stronger, he discovers that his unique ability allows him to summon more Amazonians, each stronger and more extraordinary than the last. But the more Amazons he summons, the more he uncovers the truth about their disappearance, and somehow, he is the key to bringing them back. Now, while the world's greatest summoners raise armies of dragons and mythical beasts, Mark is unknowingly rebuilding the most feared civilization in history. --------------------------------------------- *mc gets stronger fast *progressive fantasy with lots of progression over the course of chapters *high spectacular battles with incredible skills *modern fantasy setting *every chapters takes me a while — Description from novelcodex.org
