STUDY

STUDY is the name of the group that appears in the To Aru Kagaku no Railgun S Silent Party filler arc in the anime. Led by Aritomi Haruki, their only apparent goal shown so far is to show their power in their esper-obsessed city.

Members
Aritomi Haruki (apparent leader) Nunotaba Shinobu (recently recruited)                                                                                                                   4 other members of the group that are yet to be named.

Trivia

 * They are possibly the main antagonists of the Silent Party Arc.
 * If that were the case, they'd be the first main antagonists in Railgun that weren't affiliated with the Magic Side and yet still be unaffected by Kihara Gensei's actions, which is especially possible since they have shown to have low opinion of Espers.
