Intimus115 is Sherry's sorcery name—it means "Everything I offer to my lost friend." She's a Decoder working for Necessarius, known for her mastery of Kabbalah Statue art. Visually striking, she has dark skin and typically wears a black Gothic Lolita dress, with messy blonde hair that Tsuchimikado once compared to a lion's mane. She draws her spells in oil pastel or chalk to summon a golem she calls Ellis.
Sherry shows up in Academy City looking to start a war. Her plan is straightforward enough—attack someone important to either Academy City or Necessarius and watch the two sides tear into each other. But during the attempt, she tells Tōma what's really driving her: she wants science and magic to stay separated, as revenge for her late friend, also named Ellis.
Twenty years before the series, Ellis was an esper caught up in a secret collaborative experiment between Academy City and part of Necessarius. They were trying to create the first magician-esper hybrid. It didn't work. The espers involved suffered horrific injuries from magical exposure, and were then executed by the Knights of England, since the whole thing violated the truce keeping science and magic apart. Sherry blames both sides equally—for what happened to Ellis, for the cover-up, for everything. She decided the only fair response was to make them hurt the way she did.
