Summoners Are Weak? I Summon Ultraman Tiga, So Why Are You Kneeling?!

Games descend upon the world, and Blue Star enters an era where everyone can change classes. Jiang Cheng, a wastrel from Yuncheng, awakens as an E-rank Summoner and gets mocked. His scheming girlfriend turns around and throws herself into Tang Shan's arms. Too bad for them: the class he awakened is the god-tier class, Emissary of Light. Every ten levels, he can summon an Ultraman from the Land of Light to serve as his summon. For his first summon, he calls forth the embodiment of light: Tiga. The Zeperion Ray shoots straight into a hell dungeon, shocking everyone. He speed-runs the beginner's secret realm, levels up by ten, and stumbles upon a hidden S-rank quest. He thinks he'll awaken another Ultraman to help him out, but instead he awakens Dark Lugiel??? He can summon with a wave of his hand. So who's the Summoner here, you or me? After entering the Apocalypse World, he's targeted by several major families, so he contracts a hidden boss with a wave of his hand. At a genius training camp, he buys experience stones to reach Lv. 20 and summons the talkative Ultraman Zero, who combines good looks with real strength. Zero??? Many years later. The Apocalypse World descends upon the entire globe. The young man stands alone on a mountain, raising his hand slightly. Glitter Tiga, Saga, Dark Lugiel, Noah… The invading beasts cry out, “I seriously screwed up by invading this world!!”
