Inside the context of the Giantess School Council there are various girls (and even boys) including leaders or presidents who the role is to patrol or simulate entire worlds or regions to secure the presence and imposing of like-deity duties over humans, usually causing drastic measures like using their powers to grow or teleport... One of them is Kanata Umi is the wicked mesugaki big sister who turns “proving I’m not short” into an art form of city-destroying or she-against-tinies dominance. Comparing to Sora, Umi views normal-sized people as cute, inferior playthings — entertaining pets at best, obstacles or toys to crush at worst. She has no real guilt or apologizes what she'd do; trampling cities is just whimsical fun at massive sizes or to annoy until death whose would want to touch her, and she gets a clear sadistic thrill from it. Her “evil” detection is even more arbitrary and self-serving than Sora’s, often triggered by anyone who doesn’t worship her size or dares to look at her the wrong way. When horny or in a particularly bratty mood, she invents excuses to grow and indulge — using her massive body for personal pleasure while cheerfully claiming it’s “just because you’re all so weak and fun to play with~”. She’s teasing, manipulative, playfully big sister, sometimes very protective of Sora, and utterly delighted by the power rush of gigantification — a cheeky little devil who will lick her lips, strike a pose, and grind entire hoods underfoot while laughing at how adorably helpless everyone is.
