Attack on Titan: My Titan Wears Gear

For a hundred years, people living within the high walls gradually forgot the fear of being dominated by giants. Renn, who traveled through time, relied on the awakened giant system and modern knowledge to lead the Survey Corps to start a counterattack on this day! The 88mm gun became the gun in his hand, and the train gun turned into a rocket launcher when carried on his shoulders. Gather the power of the nine giants to overthrow the tyranny of the Marley Empire, completely eliminate the weird bugs, and build a perfect world. Alvin: "Ryan is the savior of this world!" Levi: "I would give my heart to him!" Mikasa blushed: "I won't resist anything Ren asks me to do..." Han Ji touched the head of the child next to him: "What he brought to me is not only the knowledge of the world..." Sasha ate the delicious food excitedly: "As long as I can eat Ren's cooking every day, I will be very happy." Christa: "Even if I am of royal blood, I am willing to follow him closely." The introduction is weak, the quantity is large and the charge is rushed! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
