Meanwhile, Konrad's secretary Karen Bombardier gives Vivi Alberic's investigation notes on Emperor Arthur before rejoining the Corps with Alberic's sword in hand. Back at Claudia's estate, she reveals to Toru's group why she has no interest with Arthur's remains and gave hers to Chaika and tells her secret.
