  It seems there's a rule [that] {as these horns sprouted out, if [I] don't search for magical girls and murderize them, that can't go}.
  • i.e. I must search for magical girls and murderize them.
  • sadame
    定め
    A rule that's been stipulated. (from sadameru 定める, "to stipulate a rule.")
    This noun is qualified by a very long {relative clause}.

    To hit. To strike. (verb.)
    Emphasizes force. (auxiliary verb.)
  • korogasu
    転がす
    To make something roll over. Trip over. To throw someone down.
    (not to be confused with korosu 殺す, which means "to kill.")

  • rashii
    らしい
    It seems. I heard. (of said rule.)
