MTL - Shoujo Grand Summoning - ~ 1964 to fight? Hit me a punch? ...

Rex was an ordinary salaryman, resigned to a dull life of monotony in a towering megacity. But his world shatters when he’s conscripted by Nexum Dynamics, a ruthless megacorporation, and thrust into a brutal war for a barren, alien world. The planet holds unimaginable riches, but it’s also swarming with the Krhyssari, an insectoid race that dominates the surface with their hive-mind precision and relentless aggression. Amid the carnage, Rex had an extraordinary encounter with Cleo, an ancient AI, a survivor of a long-extinct civilization. Cleo isn’t just an artificial intelligence; she’s a consciousness imbued with memories of her people’s interstellar empire and equipped with advanced bio-nanotechnology. Offering Rex a new purpose and unmatched power, she transforms his fragile human body into a hybrid of living metal and flesh, making him the ultimate weapon. But Cleo is more than a tool of war. As she journeys alongside Rex, her cold, logical algorithms evolve, shaped by his humanity. Together, they form a bond that transcends the boundaries of man and machine, discovering love in the midst of chaos. As Rex and Cleo fight for survival, they uncover a shared ambition, to rise as intergalactic overlords, uniting or conquering the galaxy.

The dimension storm has come, and there are a large number of different dimension fields in the earth.

Various immortal creatures such as immortals, Buddhas, demons, angels, and elves come to the earth. And those mysterious alien spheres have turned into copies of mobile games.

Others take the risk to take risks, but I am desperately playing games.
