The Shining Warrior Princess, Silver Heart (tentative name)... She is a righteous transforming heroine who fights at the risk of her life to protect people from monsters that destroy the city. However, she hasn't been a transforming heroine for very long. Her popularity with the public is still low... Even when she transforms and runs through the city to fight evil, "Who is that girl...?" Voices like this can be heard. In fact, many ordinary people don't even know that evil exists. Silver Heart's life-risking battles, and the lives saved by them... ... Now, let's talk about Ikumi, the younger sister of Mikoto Moriya, the true identity of Silver Heart. She is the only person who knows that Silver Heart is her older sister. She is bright and friendly, but a little timid, and a mama's girl who likes to be spoiled. Personality... She's also a bit of a prankster and mischievous. Iku is smiling mischievously in front of the computer. "I wonder what kind of face my big sister will make?" Imagining her sister's surprised reaction, she can't help but laugh. ... "Big sister!" Iku spots her tall, stylish, and strikingly beautiful sister on her way home and runs over, calling out to her. Since their schools are in the same direction, they commute together, and often bump into each other on their way home, like this time. "Oh... Iku-chan, are you going home now too?" Mei gives a gentle smile. With a smile on her face, she turns around and looks at Iku. "Big sister, there's something I want to show you..." "Oh, what is it?" "Never mind, let's go home quickly." Iku hurries home, practically pulling her sister along. "Oh my..." Even as she says this, Iku seems to be enjoying being pulled along. After arriving home, in Iku's room... "Actually..." Iku hides something behind her back and approaches Iku with a mischievous smile. Iku can usually guess that her sister is up to something when she makes that face, but this time it was far beyond her imagination. "Ta-da!" What Iku showed her was... It was a sausage with Silver Heart on the packaging. "Eeeeeeeh!!" Mikoto wasn't easily fazed by anything, but... Even she couldn't help but cry out because it was so unexpected. "Here you go♥" Iku smiled and handed Mikoto the box of sausages she was holding. "Here you go..." she said... Mikoto was completely panicked.
