Intimus115 is a sorceress who goes by the name "Everything I offer to my lost friend." She belongs to Necessarius and has exceptional skills in decoding. Her skin is dark, her dress is black Gothic Lolita style, and she wears unkempt blonde hair. According to Tsuchimikado, she resembles a lion's silhouette. Intimus115 specializes in creating Kabbalah Statue art using oil pastel or chalk to summon a golem called "Ellis." Sherry arrives at Academy City with the intention of attacking someone important to either Academy City or Necessarius, which she hopes will lead to war between the two factions. During her attack, Sherry reveals that she seeks revenge for Ellis, an esper from Academy City who was involved in a failed experiment 20 years ago involving Academy City and a faction of Necessarius aimed at creating the first magician-esper hybrid. The experiment resulted in major injuries to participating espers and their deaths due to Knights of England's intervention as it violated the truce between Science and Magic. Blaming both sides for Ellis' suffering and death, Sherry vowed revenge by making them suffer like she did.
