Zac Lowe is a student who moonlights as a welder. One day, he receives an order that has requested a 16-foot mecha. In fact,the more sci-fi it looks, the better! Apparently, the beautiful customer who has placed this order wishes to give the mecha to her scientist grandpa as his birthday gift. She also makes sure to claim that she's super rich.Since building a 16-foot mecha is far too difficult, Zac is about to give up on the order when he accidentally awakens a Supreme God-Tier Technology System,which allows him to successfully build the huge mecha.At the scientist's birthday banquet, the mecha makes its first appearance there. Its extremely cool and polished appearance instantly attracts everyone's attention. This leaves the customer feeling very confused.Now that she thinks about it, she might have accidentally written the wrong measurements when it comes to the mecha's height…Everyone merely thinks the mecha is just a decorative model, nothing more. But when bright blue flames erupt from the mecha's thrusters, waves of hot air propelling from it instantly steamrolls the entire scene, causing the guests to topple from their seats in shock.

In my previous life, my parents doted on my frail, sickly younger sister.For her sake, they chose a hawk beastman willing to settle in a human city as her husband.Me? They cast me into the deep sea,marrying me off to a giant shark beastman.When the apocalypse came and torrential rains drowned every human city, my parents and sister were left clinging to a rotting plank, adrift on the endless ocean.I couldn't bear to watch them die. With my giant shark husband, I dragged them down into the deep sea to safety.But resentment festered. Seeing me live comfortably while my shark beastman hunted day after day, my parents grew furious that my sister's life paled in comparison to mine. In their jealousy, they laced the fish we ate with poison and killed me.Now, given another chance at life,they've decided my sister should marry the giant shark beastman instead.My biased parents believe she will finally enjoy the blessings they once denied her.But what they don't know is this: after the cataclysm, fish become scarce. And a giant shark… does not survive on scraps. He needs flesh.
