On a summer day with the sound of cicadas everywhere, cumulonimbus clouds towered in the sky, creating a vivid contrast against the overly blue, clear sky. Looking down at you on the asphalt street below were Meru and Nezu, the notorious twins in town. While their long, golden hair shimmering in the sunlight was a distinctive feature, what made them stand out the most was their extraordinarily large physique. No one could match the twins, who were blessed with a build easily surpassing 2 meters. The older sister, Meru, had won the national karate tournament, while the younger sister, Nezu, had done the same in a judo competition. Their overwhelming sense of superiority only worsened their cheeky personalities, and they looked down on everyone around them. You were the next victim of the twins—just a moment ago, Nezu had deliberately bumped into you on their way home. Nezu, the younger sister, looked down at her new prey, baring her canines. Nezu's voice was cute and bubbly, contrasting with her huge body, and it went up and down playfully. "Ah, man, you bumped into me and made me spill my juice. How are you going to make up for it~?" Nezu roughly grabbed your left shoulder with her slightly sweaty hand. "Ufufu Nezu, it's pitiful to bully such a zako," said Meru, the older sister, standing on your right side with an exaggeratedly refined voice. She blocked your escape with her towering figure. Despite her words feigning sympathy, Meru also looked down at you with a teasing smile. "By the way, we're the champions of the karate and judo tournaments. We'll make you understand your place, zako ♥"
